Test: Trends in Chemical Properties - Question 1

Lithium shows diagonal relationship with which element?

Detailed Solution for Test: Trends in Chemical Properties - Question 1

Lithium shows similarity in prperties with that of Mg which is stated by the diagonal relationship in periodic table

Test: Trends in Chemical Properties - Question 2

If X is a nonmetal, its oxide X2O3 is expected to be a/an ______ oxide.​

Detailed Solution for Test: Trends in Chemical Properties - Question 2

Non metallic oxides are acidic.

Test: Trends in Chemical Properties - Question 3

Consider the following reaction 2A + 3F2 → 2AF3.

What is the formula for the reaction product if we substitute iodine for fluorine?​

Detailed Solution for Test: Trends in Chemical Properties - Question 3

We know that Fluorine has a charge of -1 which then means 'A' has to have a charge of +3. I got that from the AF3. If Iodine is substituted for Fluorine, the answer should be B. AI3 because Iodine also has a charge of -1. Although the actual answer should be 2AI3 because Iodine is also a diatomic element which would give us the reaction 2A+ 3I2 >>> 2AI3.

Test: Trends in Chemical Properties - Question 4

The nature of bonds in the compounds of carbon is mostly:

Detailed Solution for Test: Trends in Chemical Properties - Question 4

Carbon has 4 electron in its outermost shell. So it is difficult to loose electrons or gain electrons. That's why carbon forms covalent bond by sharing of electrons.

Test: Trends in Chemical Properties - Question 5

Which of these compounds is a basic oxide?​

Detailed Solution for Test: Trends in Chemical Properties - Question 5

A basic oxide is one which dissolves in water gives a base. MgO when dissolved in water gives Mg(OH)2 which is a base and others give acids

Test: Trends in Chemical Properties - Question 6

Amongst the elements of group 17, fluorine is most reactive owing to it’s:

Detailed Solution for Test: Trends in Chemical Properties - Question 6

 

Among the elements of group 17, fluorine is the most reactive owing to its electronegativity and small size of atom.Also extremely high oxidizing power and low dissociation energy of F-F bond is responsible for its reactivity.

Test: Trends in Chemical Properties - Question 7

If x denoted the number of valence electrons of a representative element then its valence is equal to:

Detailed Solution for Test: Trends in Chemical Properties - Question 7

 

Valence of representative element is usually equal to the number of valence electrons and/or equal to eight minus the number of valence electrons.

Test: Trends in Chemical Properties - Question 8

How many valence electrons does a carbon atom have?

Detailed Solution for Test: Trends in Chemical Properties - Question 8

A carbon atom has four valence electrons. The number of valence electrons of any atom of an element can be determined by the period table group in which the element is classified. There are a total of 18 groups on the period table group.

Test: Trends in Chemical Properties - Question 9

Aluminium belongs to group 13 and sulphur belongs to group 16 of the periodic table. The compound formed by aluminum and sulphur is:​

Detailed Solution for Test: Trends in Chemical Properties - Question 9

The valency of sulphur is 2 and the valency of aluminium is 3 hence by crossing method by which we were making the compounds in 9th standard we get it as Al2S3.

Test: Trends in Chemical Properties - Question 10

Which pair of elements from different groups resembles each other the most in their chemical properties?​

Detailed Solution for Test: Trends in Chemical Properties - Question 10

 

Be and Al show diagonal relationship and hence resembles each other closely.

Test: Trends in Chemical Properties - Question 11

Which element acts as strong reducing agent?

Detailed Solution for Test: Trends in Chemical Properties - Question 11

Reducing agents reduce others by oxidizing itself. Elements which lose electron become oxidize and reduce other elements by donating electron.

Test: Trends in Chemical Properties - Question 12

Oxygen exhibits +2 oxidation state in the compound:​

Detailed Solution for Test: Trends in Chemical Properties - Question 12

Reason behind it is that fluorine is more electronegative element than oxygen.

Test: Trends in Chemical Properties - Question 13

On moving down a group the number of valence electrons:

Detailed Solution for Test: Trends in Chemical Properties - Question 13

 

On moving down a group since the number of valence electrons remains the same, all elements exhibit same valence.

Test: Trends in Chemical Properties - Question 14

In Na2O oxidation state of sodium is:

Detailed Solution for Test: Trends in Chemical Properties - Question 14

In Na2O oxidation state of Na is +1.
It gains 2 electrons so, the oxidation state is +1 which is equal to one oxygen atom (2 electrons)

Test: Trends in Chemical Properties - Question 15

Among the following oxides, neutral oxide is:​

Detailed Solution for Test: Trends in Chemical Properties - Question 15

Neutral oxide. Neutral oxides are oxides which are neither acidic nor basic. In other words, oxides which neither react with acids or with bases are called neutral oxides. Some examples of neutral oxides are nitrous oxide (N2O), and carbon monoxide (CO).

Test: Trends in Chemical Properties - Question 16

Sodium forms which types of oxides?

Detailed Solution for Test: Trends in Chemical Properties - Question 16

Sodium oxide is more basic than Magnesium oxide. A binary compound of an element with oxygen, in which Oxygen atom is electronegative is called an oxide. The oxides which react with water and produce alkali and can neutralise acids forming salt and water are called basic oxides. Na2O, MgO are basic oxides.

Test: Trends in Chemical Properties - Question 17

The element which shows only negative oxidation state/s among following elements is:

Detailed Solution for Test: Trends in Chemical Properties - Question 17

 

Fluorine has highest electronegativity among all known elements, so it shows only negative oxidation states.

Test: Trends in Chemical Properties - Question 18

The valence of sodium with atomic number 11 is:

Detailed Solution for Test: Trends in Chemical Properties - Question 18

Valency is defined as the number of electrons in the outermost shell of an element . As the last shell(third shell) has one electron in it the valency of sodium(Na) is 1 or +1 as it looses that electron to form a cation and achieve noble gas configuration.

Sodium has 11 electrons: its atomic number is 11, so it has 11 protons; atoms are neutral, so this means sodium also has 11 electrons.

Test: Trends in Chemical Properties - Question 19

The maximum covalence of the first member of each group is:

Detailed Solution for Test: Trends in Chemical Properties - Question 19

First elements of each group in the p-block elements shows anomalous behaviour due to:

  • Small size
  • High electronegativity
  • Non-availability of empty d-orbitals

Due to these reasons, compounds of the first elements of each group are highly covalent and show maximum covalency of four.

Test: Trends in Chemical Properties - Question 20

Group 2 elements are:

Detailed Solution for Test: Trends in Chemical Properties - Question 20

The Group II elements are powerful reducing agents. A reducing agent is the compound that gets oxidised in the reaction and, therefore, loses electrons.

M = Mg, Ca, Sr,Ba --> I will be using 'M' as the general symbol for a Group II element in this topic.
