Answer 14

The number of protons in the nucleus.

Question 15

What is the mass number equal to?

Answer 15

The number of protons + the number of neutrons

Question 16

Explain Nuclide Notation.
Use Magnesium as an example.

Answer 16

24 →Mass Number
Mg →Chemical Symbol
12 →Atomic Number

Question 17

In an atom what is the number of protons equal to?

Answer 17

The number of electrons.

Question 18

How do you find the electron arrangement of an atom and draw it?

Answer 18

Look on page 6 of the data booklet.
Write the chemical symbol.
Draw one circle around the symbol for each number.
On each circle draw crosses that equal the amount stated in the data booklet.

Question 19

Define the term Isotope.

Answer 19

An isotope is an atom with the same atomic number but different mass numbers.

Question 20

Define the term Relative Atomic Mass. (RAM)

Answer 20

The average mass of all the isotopes of an element.

Question 21

Where do you find RAM for an element.

Answer 21

Page 7 of the Data Booklet.

Question 22

Apply your knowledge of RAM to evaluate the relative number of each type of isotope in a sample.

Answer 22

The closer to an isotope mass number RAM is the more of that isotope there is.

Question 23

Why do atoms form ions?

Answer 23

To achieve a full outer electron shell.

Question 24

How do you calculate RAM?

Answer 24

(mass isotope A * abundance) + (mass isotope B * abundance) / 100

Question 25

What happens to an atom when forming an ion?

Answer 25

An atom loses electrons to form a full outer electron shell.
