Covalent

________ and ionic bonds are the strong attractions that hold atoms together within compounds.

Binary compounds

________ are written with the cation first and then named by changing the ending of the second element to "ide "(always put the metal first)

Hydrogens

________ attached to polyatomic ions create compounds that are oxyacids when dissolved in water.

Binary ionic compounds

________ are composed of only 2 elements (eg.

Electronegativity

________ is a measure of the attraction of atoms for shared electrons.

Nonmetals

________ tend to react by gaining electrons so they become more reactive up a group, and also more reactive across a period.

Bohr Rutherford

________ diagrams and /or Lewis dot symbols are used to show the number of subatomic particles in atoms and help to understand bondingIons:

Ions

________ form when electrons are added /removed to produce a complete outer shell.

Multiple charges

________ are possible with atoms that possess a more complex (complicated) electron configuration (the way that the electrons are arranged) Isotopes:

anion

When a(n) ________ (negative) forms, the radius increases because extra electrons repel each other.

nucleus of some isotopes

The ________ is unstable and will decay.
