3.2 atoms into irons

Question 1

How do elements react to form compounds?

Answer 1

Elements react together to form compounds by gaining or losing electrons or by sharing electrons

Question 2

The elements in group one react with the atoms of what group?

Answer 2

Group 7

Question 3

As the atoms from group one and group 7 react what happens to the electrons?

Answer 3

As they react, atoms of group one elements can each lose one electron to gain the stable electron structure of a noble gas. This electron can then be given to an atom from group 7, which an also achieve the stable electronic structure of a noble gas.

Question 4

What is covalent bonding?

Answer 4

The attraction between two atoms that share one or more pairs of electrons

Question 5

What is ionic bonding?

Answer 5

The electric static force of attraction between positively and negatively charged ions

Question 6

What is an ion?

Answer 6

An ion is a charged particle produced by the loss or gain of electrons
