Back

nitrogen trioxide

Front

Why is an ionic bond likely to form between a metal and a nonmetal?

Back

An ionic bond forms between oppositely charged ions; metals and nonmetals are likely to be oppositely charged.

Front

What type of bond involves the sharing of electrons?

Back

covalent bonds

Front

What type of bond involves the transfer of electrons?

Back

ionic bonds

Front

Define ionic bond.

Back

An ionic bond is a type of chemical bond that occurs when one atom transfers electrons to another atom, resulting in the formation of oppositely charged ions.

Front

Define covalent bond.

Back

A covalent bond is a type of chemical bond that involves the sharing of electron pairs between atoms.

Front

What are the characteristics of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are soluble in water, and conduct electricity when dissolved in water.

Front

What are the characteristics of covalent compounds?

Back

Covalent compounds usually have lower melting and boiling points compared to ionic compounds, may not be soluble in water, and do not conduct electricity.

Front

What is the significance of electronegativity in bond formation?

Back

Electronegativity determines how strongly an atom attracts electrons; it influences whether a bond will be ionic or covalent.
