BMST Atomic Structure and Bonding 3

Question 1

Which property measures an atom's ability to attract electrons in a bond?

Accepted Answer

Electronegativity

Answer

Electronegativity is the measure of an atom's tendency to attract bonding electrons toward itself.

Question 2

How many electrons can the d subshell hold?

Accepted Answer

10

Answer

The d subshell contains 5 orbitals, each holding 2 electrons, for a maximum of 10 electrons.

Question 3

What happens to an atom when it loses an electron?

Accepted Answer

It becomes a positive ion (cation)

Answer

Losing an electron leaves the atom with more protons than electrons, giving it a net positive charge (cation).

Question 4

Which type of bond is found in metals and involves a 'sea of electrons'?

Accepted Answer

Metallic bond

Answer

Metallic bonding involves delocalized electrons that move freely among positively charged metal ions.

Question 5

In which region of the atom are protons and neutrons located?

Accepted Answer

Nucleus

Answer

Protons and neutrons are densely packed in the nucleus at the center of the atom.
