Chemistry Chemical Bonding

Front

What happens to the electrons in an ionic compound?

Back

Electrons transfer from one atom to another.

Front

What type of atoms are bonded in a covalent compound?

Back

Covalent compounds are formed by the bonding of two nonmetals.

Front

What is the formula for potassium and oxygen?

Back

The formula is K₂O.

Front

What is the electrical conductivity of a covalent compound?

Back

Covalent compounds generally have poor electrical conductivity.

Front

What is the chemical formula for dihydrogen monosulfide?

Back

The formula is H₂S.

Front

Define ionic bond.

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

Front

Define covalent bond.

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

What is the difference between ionic and covalent compounds in terms of melting points?

Back

Ionic compounds typically have high melting points, while covalent compounds usually have lower melting points.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.
