Answer 1

True

Question 2

What are the three particles in an atom

Answer 2

Protons, electrons and neutrons

Question 3

What is the mass of an electron

Answer 3

0 a.m.u

Question 4

What is the charge of an electron

Answer 4

Negative

Question 5

What is the mass of a proton

Answer 5

1 a.m.u.

Question 6

What is the charge of a proton

Answer 6

Positive

Question 7

What is the mass of a neutron

Answer 7

1 a.m.u.

Question 8

What is the charge of a neutron

Answer 8

Neutral

Question 9

What location are the electrons in the atom

Answer 9

The shells around the atom

Question 10

What is the location of the protons in the atom

Answer 10

The nucleus

Question 11

What part of the atom are the neutrons located

Answer 11

The nucleus

Question 12

Why is the atom neutral

Answer 12

Because the number of protons = number of electrons

Question 13

What is the charge of the nucleus

Answer 13

Positive because there are only protons and neutrons in the nucleus and the protons are positive and the neutrons are neutral

Question 14

How do you figure out the number of protons

Answer 14

Atomic number = number of protons

Question 15

How do you figure out the number of electrons

Answer 15

Number of protons = number of electrons

Question 16

How do you figure out the mass number

Answer 16

Number of protons + number of neutrons

Question 17

How do you figure out the number of neutrons

Answer 17

Mass number - atomic number

Question 18

In nuclide notation What does the top number mean

Answer 18

Mass number

Question 19

In nuclide notation what does the bottom number mean

Answer 19

Atomic number

Question 20

RAM=

Answer 20

RAM= (%abundance of isotope 1 x mass) + (%abundance of isotope 2 x mass)
