Bonds between metals and nonmetals tend to be ionic, but bonds between nonmetal atoms tend to be covalent.

explain why this is true, using your understanding of electronegativity and ionization energy for these groups of elements.

Bond type depends on differences in electronegativity.

Metals and nonmetals tend to have large differences in electronegativity.

Nonmetals tend to have smaller differences in electronegativity.

Ionic bonds form between atoms that have large electronegativity differences.

Covalent bonds form between atoms with small electronegativity differences.

warm front forms when a moist, warm air mass slides up and over a cold air mass. as the warm air mass rises, it condenses into a broad area of clouds. a warm front brings gentle rain or light snow, followed by warmer, milder weather.
