Name three types of particle in an oxygen atom. State the mass and charge of each particle

These three particles can be found in all atoms: PROTON_1_+1, NEUTRON_1_0, ELECTRON_1/2000_ -1

1 of 5

The element boron has 5 protons. How many electrons does a boron atom have in its outer shell?

A boron atom would have 5 electrons. This means it has an electron configuration of 2,3. Therefore it has 3 ELECTRONS IN ITS OUTER SHELL

2 of 5

Describe how to work out the electron configuration of a of an atom given its atomic number.

The atomic number tell us how many protons there are which means we know how many electrons are in it. Then you have to remember how many electrons can fit in each shell (2,8,8,8). You can now work out the electron configuration of any given element.

3 of 5

Work out the electron configuration of potassium using the information below.

the electron configuration of potassium is...... 2,8,8,1

4 of 5

What do the mass number and atomic number represent?

MASS NUMBER - the number of protons and neutrons in an element. ATOMIC NUMBER- the number of protons found in an element.
