In the Modern Periodic Table, if an element with atomic number ‘X’ is an inert gas, then an element with atomic number (X-1) will be placed in:a)Group 16b)Group 17c)Group 15d)Group 18Correct answer is option 'B'. Can you explain this answer?

Question

In the Modern Periodic Table, if an element with atomic number &#8216;X&#8217; is an inert gas, then an element with atomic number (X-1) will be placed in:&#8203;a)Group 16b)Group 17c)Group 15d)Group 18Correct answer is option 'B'. Can you explain this answer?

Answer

All the Noble gases are placed in the group 18 and all elements are placed in the order of increasing atomic number. Therefore, the elements of atomic number before the Noble gas is placed in the before group of the period of Nobel gas which is group 17.

Answer

The inert gases are placed in the group 18 hence the group 17 will be correct option.

Answer

Actually inert gas processes group 18 in Modern Periodic Table with an electronic configuration of fully filled valence shell.

So One Less than group 18 is group 17 and hence the correct answer!!

Group 17 is known as Halogen group containing the following atoms :

The halogen elements are fluorine (F), chlorine (Cl),
bromine(Br), iodine (I), astatine (At), andtennessine (Ts)

Answer

Incorrect answer given......

Answer

All the Nobel gases are placed in group 18 and all elements are placed in the order of increasing atomic number. therefore, and the element of atomic number before the Nobel gas is placed in the before group of the period of Nobel gas which is group 17.

Answer

The element X is an inert gas. Therefore it will be placed in the group 18 elements. The another element with atomic no. of x-1 will be a halogen(since element x is an inert gas, it's valence shell would have 8 electrons, so the preceding element will have 8-1, i.e., 7 electrons) Since halogen are placed in group 17 hence that element will also be placed in group 17

Answer

The element with Atomic Number (X-1) will be placed only in GROUP 17 and not 18.

Answer

Inert gas belong from group 18 so X-1 means x loose 1 electron than it will come under group 17 so 17 is correct ans

Answer

Group 17<div><br /></div>

Answer

On subtracting 1 from the atomic number of inert gas .....tere are only 7 valence electron left in last shell so it's group is 17

Answer

This is because in a period elements are arranged in increasing order of their atomic no.
Since inert gases are in group 18 therefore an element with atomic no. x-1 will be placed in group 17 (Halogens)

Answer

Inert gases r placed in 18th group in modern periodic table...so (x-1) will be placed in 17th group

Answer

17

Answer

Incorrect answer

Answer

Yeah, I just gave the test. It's impossible to have the answer Group 18 as inert gases lie on this group only. .

Answer

Correct ans is group 17. x is inert gas,so for example ne is V111 A group . ne atomic no 10.
x -1 =10-1 =9 so the 9 atomic no belongs to V11 A group..it is nothing but group 17

Answer

B is correct.

Answer

All inert gas is situated if 18 group of modern periodic table which is x and x-1 which means 18 -1=17

Answer

Answer should be option B) group 17

Answer

X=18
(x-1)=17
so answer is 17 group

Answer

It's possible because x-1 does not remains inert gas . let us take example of argon(18) it is inert gas but if we subtract one electron from it it will become chlorine (17) hence it lies in 17th group only  so the answer is correct

Answer

Incorrect answer given.              It's correct answer is B.      because inert gas is placed in group 18 .so, answer must be group 17.

Answer

Correct answer is group 17 and not group 18..
the answer said is just impossible

Answer

If the elements X is inert then it is placed in group 18 so an element with atomic number (X-1) should be of group 17.

Answer

Correct answer is B as given an atomic number is subtracted from atomic number of Noble gas so the element should belong to 17 group

Answer

Yes, option B is correct as in question X is an inert gase so it is in 18 group so X-1 is in group 17.
