Number of electrons on outside shell

Question 10

What does the period number tell us?

Answer 10

Number of shells

Question 11

What do we know about atoms of the same element?

Answer 11

They all have the same number protons, and so same atomic number

Question 12

How many electrons does a full outer shell have?

Answer 12

8

Question 13

How many electrons does a full inner shell have?

Answer 13

2

Question 14

What do electrons do to give an atom a full outer shell?

Answer 14

Electrons move between atoms to give each other full shells

Question 15

What does it mean for an atom to be a neutral atom?

Answer 15

It has the same number of neutrons and electrons

Question 16

What are ions?

Answer 16

Atoms with a positive or negative charge due to electrons moving around

Question 17

What are atoms that have lost electrons called?

Answer 17

Cations

Question 18

What charge will atoms that have lost electrons have? What are they called?

Answer 18

Positive charges, Cations

Question 19

What are atoms that have Gained electrons called?

Answer 19

Anions

Question 20

What charge will atoms that have Gained electrons have? What are they called?

Answer 20

Negative charges, anions

Question 21

What type of ions do metals always form?

Answer 21

Cations

Question 22

What type of ions do non metals always form?

Answer 22

An anion

Question 23

What are the ending of non metals, that tell us that it’s an ion?

Answer 23

Ide

Question 24

Draw a lithium atom

Answer 24

2 electrons inner shell

1 electron outer shell

Question 25

Draw a lithium ion

Answer 25

[ two inner shell electrons. +1. ]

Question 26

What is the formula for calcium bromide? Why?

Answer 26

Calcium - ca = +2
Bromide - Br = -1

= Ca^2+ Br^-1 = CaBr{little2} = 0

2 and 1 both fit into 2
Not -2 because it already has a positive charge, and Bromine 2 has an overall charge of -2

Question 27

When a metal and a non metal form an ionic bond what does the ending of the non metal change to?

Answer 27

ide, telling us it’s an ion

Question 28

What are two metals that form an ion called?

Answer 28

Polyatomic ions

Question 29

What do the numbers in CO{little3}^2- tell us?

Answer 29

2 = it has a negative charge of two. Has gained two electrons

3=3lots of oxygen are bonded to one carbon
