Generally high melting & boiling points

• Ionic compounds

• Covalent compounds

In ionic bonds, electrons are ​ (a)   rather than being shared. When writing ​ a Lewis dot structure for an ionic compound, the elements' symbols are shown in a ​ (b)   with their charge and the electrons that make the ion stable. In a covalent bond, the valence electrons are ​ (c)   . When writing a Lewis dot structure for a covalent compound, the elements' symbols are written down, and the ​ (d)   electrons surround each symbol. At least one ​ (e)   of electrons are shared between the two elements.

What kind of bond forms between metals and nonmetals?

(a)  

• Ionic bonds

• Covalent bonds

• Hydrogen bonds

• Molecular bonds

Atoms of ​ (a)   elements most easily achieve a stable energy level by losing electrons from their outer level.

​ (b)   generally gain stability by gaining an electron.

Compounds that result when metals and nonmetals bond ionically with each other are called ​ (c)   compounds.

• metallic

• Nonmetals

• ionic

When a nonmetal gains electrons, it becomes a(n) (a)   .

• anion

• cation

• Isotope

• element

An atom that has gained or lost an electron is called a(n) (a)   .

• ion

• particle

• atom
