Answer 4

Positive

Question 5

What charge is an Electron?

Answer 5

Negative

Question 6

What charge is a Neutron

Answer 6

Negative

Question 7

What is the number of Protons in an atom called?

Answer 7

Atomic number

Question 8

How are the elements in the periodic table arranged ?

Answer 8

By atomic number

Question 9

What is the number of Protons and Neutrons called?

Answer 9

Mass number

Question 10

True or False Atoms carry an equal number protons and electrons

Answer 10

True

Question 11

True or False You can find the number of protons and electrons in an atom by looking up it atomic number in the periodic table

Answer 11

True

Question 12

What is an ion?

Answer 12

A charged atom or group of atoms

Question 13

What causes an ion to take a negative charge?

Answer 13

The gain of one or more electrons

Question 14

What causes an ion to take a positive charge>

Answer 14

The loss of one or more electrons

Question 15

If you are given the mass number an the atomic number how can you work out the number neutrons protons and electrons?

Answer 15

Step 1 the atomic number tells you the number of protons, the number of electrons will also be the same.
Step 2 Use this equation to work out the number of neutrons :
Number of neutron = mass number - atomic number

Question 16

What is the relative charge of a proton?

Answer 16

+1

Question 17

What is the relative charge of an electron?

Answer 17

-1

Question 18

What is the relative charge of a neutron?

Answer 18

No charge they are neutral

Question 19

What is the mass number?

Answer 19

Number of protons plus neutrons

Question 20

What is the atomic number?

Answer 20

Number of protons which is the same as the number of electrons

Question 21

What is the relative mass of protons neutrons and electrons?

Answer 21

Proton = 1
Neutron = 1
Electron = very small it would take almost 2000 electrons to get the same mass number as proton and neutrons.

Question 22

How are Electrons arranged in an atom?

Answer 22

In shells

Question 23

How many electrons can be held in each shell?

Answer 23

In the inner shell it can hold just 2
In the second layer it can hold 8 electrons
Any layers after this can be filled up to 8 but the layers before this need to be full

Question 24

What is electronic structure?

Answer 24

It is a way of recording the numbers of each successive energy level. Beryllium has an atomic structure of 4 so its electronic structure would be 2.2

Question 25

How does electronic structure relate to the periodic table?

Answer 25

Atoms that are in the same group of the periodic table will have the same number of electrons on the outer shell For example group 2 elements all have 2 in their outer shell

Question 26

How does electronic relate to reactivity?

Answer 26

Elements in the periodic table are also ordered in reactivity. Atoms in the same group react in a similar way because they have the same number of electrons in the outer shell
