What is the plum pudding model of the atom?

A ball of positive charge with negative electrons distributed into it

What did the gold foil experiment prove?

That atoms have a dense nucleus with a positive charge

What is the atomic number of an atom?

The number of protons in an atom

What are groups in the periodic table?

The columns, numbered 1, 2, 3, 4, 5, 6, 7, 0

What links the group number of an atom and the electron distribution?

How many electrons in the outer shell

Why did Mendeleev put some elements in groups?

Because they had similar chemical properties

Why did Mendeleev leave gaps in his periodic table?

For elements that had not been discovered yet

Where are the non-metals located on the periodic table?

Top right of the periodic table

An atom which has lost or gained an electron

What charged ion will a group 3 metal form?

3+ (three electrons in the outer energy level)

Name the force of attraction between ions in an ionic compound.

Electrostatic (force of attraction between positive and negative ions)

What charge will an ion of fluorine take?

1- (7 electrons in the outer shell, needs to gain one)

If something has lost electrons, what charge will it have?

Positive (because they have lost a negative!)

Why do atoms transfer electrons in ionic bonding?

So that they can have full outer shells

Explain in terms of electrons what occurs when lithium bonds with chlorine.

One electron transferred from lithium to chlorine

Explain in terms of electrons what occurs when magnesium bonds with oxygen.

Two electrons transferred from magnesium to oxygen

What charge will an ion of oxygen take?

2- (6 electrons in outer shell so needs to gain two)

Explain in terms of electrons what occurs when beryllium bonds with oxygen.

Two electrons transferred from beryllium to oxygen

What happens in terms of electrons when magnesium bonds with chlorine?

One electron is transferred from magnesium to two different chlorine atoms

Why do sodium ions and chlorine ions form an ionic bond?

There is an electrostatic force of attraction between oppositely charged ions

Why don't sulphur ions and oxygen ions form ionic bonds with each other?

Both have negative charges so would repel

A crystalline structure made of alternating positive and negative ions held together by electrostatic forces of attraction
