Proton (P+)
Neutron (No)
Electron (E-)

Question 4

What do we use to measure the masseuse of the sub atomic particles?

Answer 4

AMU. (Atomic Mass Unit)

Question 5

Where are protons found?

Answer 5

They are found in the nucleus of an atom

True or False….

All protons in the universe are identical

Answer 6

True.

Question 7

what AMU is 1 proton equal to?

Bonus: 1 gram of mass is equal to how many protons?

Answer 7

Answer 13

1 AMU

Question 14

What are electrons?

Answer 14

Negative charged particles that fly around the nucleus at high speeds.

Question 15

Answer 15

0 AMU

1/036 AMU

Question 16

How are electrons arranged?

Answer 16

Electrons are arranged in energy levels or energy shells

Question 17

How many electrons can the first energy level hold?

Answer 17

The first energy level can hold a maximum of 2 electrons

Question 18

How many electrons can every energy level after the first one hold?

Answer 18

Every shell after the first one can hold a maximum of 8 electrons

Question 19

What are the chemical properties of an element determined by

Answer 19

The chemical properties of an element are determined by the electrons in its outer most shell. These are the valence electrons in the valence shell
