Question 7

What do atoms take place in chemical reactions to achieve?

Answer 7

A full outer shell of electrons

Question 8

Why does an atom want to achieve a full outer shell of eletrons?

Answer 8

To become stable (like a noble gas)

Question 9

When an atoms gains electrons, does the charge increase or decrease?

Answer 9

Decreases as there will be more electrons than protons and electrons have a negative charge

Question 9

When an atoms loses electrons, does the charge increase or decrease?

Answer 9

Increases as there will be more protons than electrons and protons have a positive charge

Question 10

How will elements in groups 1, 2 and 3 achieve a full outer shell?

Answer 10

By losing electrons (a positive charge)

Question 11

How will elements in group 5, 6 and 7 achieve a full outer shell?

Answer 11

By gaining electrons (a negative charge)

Question 12

How do metals achieve a full outer shell?

Answer 12

Losing electrons

Question 13

What is the name for a positively charged ion?

Answer 13

A Cation (cat-ion)

Question 14

How do you draw an ion?

Answer 14

Draw the ion with all of the shells that it has full. If it is groups 1, 2 or 3 it will lose one shell. Draw all the shells to be as full as they can due to electron configuration. Draw a square bracket around the whole ion and write the charge in the top right corner (on the outside)
