Ionic and Covalent Bonds

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a nonmetal.

Front

What is a covalent bond?

Back

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

Front

How do you name ionic compounds?

Back

When naming ionic compounds, the metal is named first followed by the nonmetal, which is named with an '-ide' suffix.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are the outermost electrons of an atom and are crucial in determining how an atom can bond with others to achieve stability.

Front

What happens when an atom gains an electron?

Back

When an atom gains an electron, it becomes a negative ion (anion).

Front

What is the formula for zinc fluoride?

Back

The formula for zinc fluoride is ZnF₂.

Front

How many valence electrons does oxygen have?

Back

Oxygen has 6 valence electrons.

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.

Front

What type of bond is formed between two nonmetals?

Back

A covalent bond is formed between two nonmetals.

Front

What is a positive ion?

Back

A positive ion, or cation, is formed when an atom loses one or more electrons.
