Isotope

300

When nonmetals combine with metals, ___ bonds form.

What is ionic?

300

300

What are positively charged ions called? What type of elements form cations (metals or nonmetals) when bonded?

Cations, Metals

400

An element that gains or loses electrons becoming charged.

Ion

400
The type of bonding that occurs when there are positively-charged ions in a sea of electrons.
What is metallic bonding?
400

What are the most common elements on the periodic table (metal, nonmentals, metalloids)?

What is the difference between a polar and a nonpolar molecule?

A polar molecule has an uneven distribution of electrons, meaning one side of the molecule is slightly positive and the other side is slightly negative

 A nonpolar molecule has an even distribution of electrons, with no distinct positive or negative poles
