Answer 3

-1

Question 4

What is the relative mass of a proton?

Answer 4

1

Question 5

Question 7

What is the modern periodic table ordered in?

Answer 7

Atomic number

Question 8

What are columns on the periodic table known as?

Answer 8

Groups

Question 9

What are rows on the periodic table known as?

Answer 9

Periods

Question 10

What is atomic mass?

Answer 10

The total relative mass of the nucleus of an atom

Question 11

What is the nucleus of an atom?

Answer 11

It is in the centre of the atom and is made up of protons and neutrons. It contains most of the atom’s mass.

Question 12

What does the atomic number tell you?

Answer 12

The atomic number is equal to the number of protons as well as the number of electrons

Question 13

How are electrons arranged?

Answer 13

In shells that surround and orbit the nucleus.

Question 14

What is the maximum number of electrons in an atoms first shell?

Answer 14

2

Question 15

What is the maximum number of electrons in an atoms second shell?

Answer 15

8

Question 16

What is the maximum number of electrons in an atoms third shell?

Answer 16

8

Question 17

What does the group number tell you about the electronic configuration of an atom?

Answer 17

The amount of electrons in its outer shell

Question 18

What does the period number tell you about an atoms electronic configuration?

Answer 18

How many shells of electrons that element has

Question 19

What did Dimitri Mendeleev create?

Answer 19

The first periodic table

Question 20

How did Mendeleev order the elements?

Answer 20

In order of atomic mass

Question 21

What side of the periodic table would you find metals?

Answer 21

Left

Question 22

What side of the periodic table would you find non metals?

Answer 22

Right

Question 23

Where did Mendeleev put elements with similar properties?

Answer 23

In the same row

Question 24

Which group contains the alkali metals?

Answer 24

Group 1

Question 25

Where are atoms with similar properties on the periodic table?

Answer 25

The same group

Question 26

How do you find the number of neutrons in an atom?

Answer 26

Atomic mass - number of protons/atomic number

Question 27

What is the total relative charge of an atom?

Answer 27

0

Question 28

What is the total relative charge of the nucleus of an atom?

Answer 28

+1

Question 29

Name 3 key scientists linked with atomic structure

Answer 29

John Dalton, JJ Thompson, Ernest Rutherford

Question 30

Give two differences between Dalton’s model of the atom and today’s model of the atom

Answer 30

- Dalton believed atoms **couldn’t be broken up into smaller particles**, now we know they’re made up of protons, neutrons and electrons - Dalton believed **all atoms in the same element were the same**, now we know isotopes of the same element have different numbers of neutrons

Question 31

Where is most of the mass concentrated in an atom?

Answer 31

The nucleus

Question 32

Compare the size of the nucleus to the overall size of the atom

Answer 32

It is **very small** compared to the overall size of the atom

Question 33

What did Mendeleev do with undiscovered elements in his periodic table?

Answer 33

He left gaps for where they would be for when they were discovered in the future
