Q

Proton equal the number of ____________ in an atom.

A

ELECTRONS!

*Protons equal the same number as electrons

2
Q

Define isotopes

A

Atoms of the same element that have the same number of protons but different numbers of neutrons

3
Q

Define ionic bond

A

The bonding that involves a transfer of electrons

Q

Elements are made up of one type of _________.

A

Atom

Define metalloid

A

An element that conducts electric current better than a nonmetal but as well as a metal. (In the middle of nonmetals and metals)

7
Q

What is the valence number if a atom?

A

The number of electrons of the outermost energy level

8
Q

What makes an atom neutral?

A

When both protons and electrons are the same number (equal)

9
Q

Define molecule. Give an example.

A

When a group of atoms are bonded together.

An example would be water.

Q

Elements in the same family or group have the same ___________ ____________

A

Bonding Electrons

15
Q

Define covalent bond.

A

Bonding in which electrons are shared.

16
Q

Why don’t electrons leave the atom?

A

Because electrons are negative and protons are positive - they go together
