16
Q

Chemical element

A

Described as a quantity of matter composed of 1 type of atom

17
Q

Atoms

A

Smallest units of matter that retain the properties of the element
- they are composed of subatomic particles
Protons, neutrons, and electrons

18
Q

Protons

A

Positively charged

19
Q

Neutrons

A

Neutral, no charge

20
Q

Electrons

A

Negatively charged

21
Q

Molecules

A

Two or more atoms, with incomplete outer electron shells can be joined by bonds to create a stable molecule

22
Q

Compound

A

Two or more different atoms are joined

23
Q

Covalent bonds

A

Involve sharing of electrons to form an outer electron ( valence) shell

24
Q

Ionic Bond

A

Involve one or more atoms donating electrons to other atoms to form stable outer electron shells for all atoms involved in the bond

25
Q

Ions

A

Result when an atoms of a compound joined by ionic bonds give up or Gail electrons & become positively or negatively charged

26
Q

Chemical reactions

A

Are making and breaking bonds between atoms to store or release energy

This is the basis of all living processes

27
Q

Metabolism

A

The sum of all the biochemical reactions in the body ; anabolic reactions and dehydration synthesis

28
Q

Anabolic reactions

A

Or synthesis reactions require energy to combine simple substances( monomers) into complex ( polymers) they use energy to form bonds

29
Q

Dehydration synthesis

A

Is An example of an anabolic reactions
- here the polymers are built by joining together with the removal of a molecule of water.

  • using ATP energy process
  • occurs in our cells to build proteins, glycogen, and lipids
