How are mixtures different from compounds in terms of their separability and composition?

Detailed Solution for Test: Elements, Compounds and Mixtures & Structure of Atom - Question 1
Mixtures differ from compounds primarily in their separability. Mixtures can be easily separated using physical methods like filtration or evaporation, as the components do not form chemical bonds with each other. On the other hand, compounds are chemically bonded entities that require chemical processes to break down into their individual elements. This distinction in separability is crucial in understanding the difference between mixtures and compounds.

What characteristic defines a mixture in terms of its composition and structure?

Detailed Solution for Test: Elements, Compounds and Mixtures & Structure of Atom - Question 2
A mixture is defined by the absence of chemical bonding between the substances it comprises. This means that in a mixture, the components retain their individual properties and can be separated using physical methods like filtration or evaporation. This characteristic distinguishes mixtures from compounds, where the elements are chemically bonded together to form a new substance.

What is the primary function of protons and neutrons in an atom?

Detailed Solution for Test: Elements, Compounds and Mixtures & Structure of Atom - Question 3
Protons and neutrons are located in the nucleus of an atom and contribute most of the mass to the atom. While protons carry a positive charge and neutrons are neutral, their main function is to provide mass and stability to the atom. This mass is essential in determining the overall properties of the element.

Which subatomic particle contributes the least to the overall mass of an atom?
Detailed Solution for Test: Elements, Compounds and Mixtures & Structure of Atom - Question 4
Electrons contribute the least to the overall mass of an atom. Although electrons play a crucial role in chemical reactions and the formation of bonds between atoms, their individual mass is extremely small compared to that of protons and neutrons. The majority of an atom's mass is concentrated in the nucleus, where protons and neutrons reside, while electrons mainly contribute to the atom's charge and reactivity.

Which subatomic particles constitute the particles of an atom?
Detailed Solution for Test: Elements, Compounds and Mixtures & Structure of Atom - Question 5
Protons, neutrons, and electrons are the three main subatomic particles that constitute an atom. Protons and neutrons are located in the nucleus of the atom, while electrons orbit around the nucleus in various energy levels.

What is the relative atomic mass of hydrogen?
Detailed Solution for Test: Elements, Compounds and Mixtures & Structure of Atom - Question 6
Hydrogen possesses a relative atomic mass of 1. This means that 12 hydrogen atoms would equate in mass to a single carbon atom. Hydrogen is the lightest and simplest element in the periodic table.

What does the atomic number (proton number) of an atom represent?
Detailed Solution for Test: Elements, Compounds and Mixtures & Structure of Atom - Question 7
The atomic number (proton number) of an atom represents the number of protons present in the nucleus of the atom. This number is crucial as it determines the element's identity and its place on the Periodic Table. Each element has a unique atomic number, which corresponds to the number of protons in its nucleus.

How can you find the number of neutrons in an atom?
Detailed Solution for Test: Elements, Compounds and Mixtures & Structure of Atom - Question 8
To find the number of neutrons in an atom, you need to subtract the atomic number (proton number) from the mass number (nucleon number). Neutrons, along with protons, make up the nucleus of an atom. This difference between the mass number and the atomic number gives us the number of neutrons in the atom.

What does the mass number of an atom represent?
Detailed Solution for Test: Elements, Compounds and Mixtures & Structure of Atom - Question 9
The mass number (nucleon number) of an atom represents the total sum of protons and neutrons present in the nucleus of the atom. It is denoted by the symbol 'A' in atomic notation. This number helps us calculate the atomic mass of the atom and differentiate one isotope of an element from another based on the number of neutrons present.

How is the number of electrons in a neutral atom related to the number of protons?
Detailed Solution for Test: Elements, Compounds and Mixtures & Structure of Atom - Question 10
In a neutral atom, the number of electrons is equal to the number of protons. This equilibrium of positive protons in the nucleus and negative electrons orbiting the nucleus ensures the overall charge of the atom is neutral. This balance of positive and negative charges maintains the stability of the atom.
