chemistry ch 8

In covalent compounds, atoms become chemically stable by sharing their valence electrons

• true

• false

noble gases are generally non-reactive because they already have a complete valence shell

• true

• false

a diatomic molecule is one that is made of only 2 different elements

• true

• false

hybrid orbitals result from the mixing of atomic orbitals to hold lone electron pairs and single electrons for bonding

• true

• false

electron affinity is the likelihood of an atom to accept an electron

• true

• false

electron affinity and electronegativity are opposite of one another

• true

• false

an oxyacid is composed of a hydrogen atom bonded to a polyatomic anion

• true

• false

all noble gases have the same valence electron configuration

• true

• false

a sigma bond is formed between two atoms when valence atomic orbital of one atom overlaps with other atoms

• true

• false

all of the bond lengths in a compound having resonating structures are identical

• true

• false
