100

What is the key word for covalent bonds.

Sharing

100

What is the action of a covalent bond?

give and take of electrons

200

What is the electric charge of a proton?

Positive

200

The atomic number of an atom is equal to the number of _____________ in the nucleus.

Protons

200

Where is the first energy level located?

Closest to the nucleus

200

What two things must atoms have for a covalent bond to occur?

Strong attraction, unfilled outer energy levels

200

When an atom loses or gains an electron, it is called an ___________ 

Ion

300

What is the electric charge of an electron?

Negative

300

Atoms of the same element with different numbers of neutrons are called _____________ of that element.

Isotopes

300

What is the number of electrons that can go in the first two energy levels. Separate them into their energy levels

2, 8

300

What is the attraction that brings covalent bonds together?

The attraction between valence electrons of one atom to the nucleus or the protons of another atom. 

300

A ______________ is a positive ion, and a ____________ is an negative ion. 

Cation, anion

400

What is the electric charge of a neutron?

It has no charge, or neutral. 

400

Are the elements in columns or rows are similar with their reactions?

Columns

400

Atoms in the same column on the periodic table have the same number of _____________________________. 

valence electrons

400

Atoms will covalently bond until when? 

Their outer energy levels are full

400

Why do atoms in an ionic bond stay together?

Because gaining and losing an electron gives them a positive and negative charge. 
500

What is the place where the protons and neutrons are found? Where are the electrons found?

Nucleus, Energy levels

500

The atomic mass of an element is the__________________________________________________

average mass of the different isotopes of the element

500

What two things do the valence electrons tell us?

How many electrons are in the outer level, how reactive the element will be. 
500
