Sample Questions

1multiple correct

Which of the following particles are found in the nucleus of an atom?

Show answer

Protons, Neutrons

The nucleus contains protons (positively charged) and neutrons (neutral). Electrons revolve around the nucleus in orbits. Alpha particles are not fundamental particles of atoms.

2true false

Isotopes are atoms that have the same atomic number but different mass numbers.

Show answer

True

Isotopes are atoms of the same element with the same number of protons (same atomic number) but different number of neutrons (different mass numbers).

3multiple correct

Which of the following statements about noble gases are correct?

Show answer

They have complete outermost electron shells, They are chemically inactive

Noble gases have complete outermost shells (8 electrons except helium which has 2) making them stable and chemically inactive. They don't readily form compounds.

4multiple choice

What type of bond is formed between two non-metals?

Show answer

Covalent bond

When two non-metals combine, they share electrons to achieve stable configuration, forming covalent bonds. Ionic bonds form between metals and non-metals.
