Q

What is a native metal?

A

17
Q

How do you work out the number of neutrons in an atom?

A

You take away the mass number (at the top) by the Atomic number (at the bottom).

18
Q

How do you work out the number of protons and electrons in an atom?

A

After working out the number of neutrons, the remainder is the number of protons/electrons

19
Q

How do you work out the electric configuration?

A

It is the number of electrons closest to the nucleus on the diagram and the number of electrons furthest from the nucleus on the diagram, e,g, 2,1.

20
Q

What is decomposition?

A
