ASSMENT WEEK 1 CHEMISTTRAY

Question 1

What is the atoms radius

Answer 1

1x10 to the -10m

Question 2

What is inside of the nucleus

Answer 2

Inside the nucleus contains protons and neutrons

Question 3

Keyfeature about the neculeas

Answer 3

It is in the middle of the atom, the nucleus has a radius of around one times 10 to the power of -14. It has a positive charge because of the protons, almost the whole mass of the atom is concentrated in the nucleus

Question 4

Key features of electrons

Answer 4

They move around the nucleus in electron shells

They’re negatively charged and tiny but they cover a lot of space

The volume of the orbits determines the size of the atom

Electrons have virtually no mass

Question 5

Particle. Relative Mass. Charge
Proton. 1. +1
Neutron. 1. -0
Electron. Very small. -1

Answer 5

G

Question 6

The number of protons equal the same amount of electrons

Answer 6

.

Question 7

In an eye on the numbers of protons Doesn’t eat food numbers of electrons. This mean it has an overall charge. For example an ion with a two minus charge has two more electrons than protons.

Answer 7

.

Question 8

23
Na. The 23 is the mass number which tell you the total amount of protons and neutrons in the atoms
11. The number 11 is atomic number which tells you how many protons there are in the atom

Answer 8

.

Question 9

Periods go side ways

Grouos go downwards

Answer 9

.
