Lesson 3 - True or False

When two atoms of the same or different elements approach each other, the energy of the combination of the atoms becomes less than the sum of the energies of the two separated atoms at a small distance.

• True

• False

Two atoms have combined, or a bond is formed between the two atoms that is called a physical bond.

• True

• False

According to the Kossel's Theory, sodium wants to gain one more electron to reach argon's electron configuration.

• True

• False

In case of O₂, an oxygen atom donates 2 electrons for another atom to form a bond.

• False

• True

The shared pair of electrons contributes towards the stability of both the atoms and is said to be responsible for "bonding" between the two atoms.

• True

• False

The covalent bonds are called non-polar bonds which are normally formed by two same atoms.

• False

• True

If the shared electron pair comes from one atom to make the bond, it is called a coordinate covalence.

• True

• False

If the shared electron pair is extracted more by an atom that bond is called non-polar pair.

• True

• False

In a Lewis representation, the electrons shown to be involved in the bond formation are called bonding electrons; the pair of electrons is called "bond pair".

• True

• False

The pairs of electrons not involved in the bonding process are called "lone pairs".

• False

• True
