Atomic Chemistry

Question 1

What make up atoms?

Answer 1

Electrons, protons and neutrons

Question 2

What charges do thy all have?

Answer 2

Protons = positive charge
Neutron = no charge
Electrons = negative charge

Question 3

What is the nucleus made of?

Answer 3

Protons and neutrons (they have the same amount)

Question 4

Which rings hold how many electrons?

Answer 4

Ring 1 = 2 electrons
Ring 2 = 8 electrons
Ring 3 = 8 electrons
Ring 4 = 8 electrons

Question 5

Do protons, electrons and neutrons have a mass

Answer 5

Protons have a mass
Neutrons have a mass
Electrons have no mass

Question 6

Where are they all found?

Answer 6

Proton and neutrons in the nucleus
Electrons in the energy level

Question 7

How are elements arranged on the periodic table?

Answer 7

In terms of their mass number in ascending order. It makes it easier to find specific number

Question 8

How are elements shown on the periodic table?

Answer 8

1. Atomic number
2. Element symbol
3. Element name
4. Atomic mass/mass number

Question 9

What are the columns and rows on the periodic table called

Answer 9

Rows = periods (7)
Columns = groups (18)

Question 10

What determines the element

Answer 10

The no. of protons ( adding protons moves to the next elements)

Question 11

How do we find out the amount of protons?

Answer 11

The same as the atomic number

Question 12

How do we find out the number of neutrons?

Answer 12

Atomic mass minus the atomic number

Question 13

How do we find out the number of electrons?

Answer 13

They are equal to the number of protons

Question 14

What relation do elements in the same period have?

Answer 14

They all have the same number of energy levels

Question 15

What relation do elements in the same group have?

Answer 15

They have the same number of valence electrons (number of electrons in the outer most shell

Question 16

Give me 5 characteristics of metals

Answer 16

Lustre (shiny)
Sonorous
Good conductors of heat and electricity
Malleable
Ductile

Question 17

Give me 3 characteristics of non-metals

Answer 17

Brittle
Non-malleable nor ductile
Poor conductors of heat and electricity

Question 18

On which side of the periodic table are non-metals and metals

Answer 18

Left side up to the metalloids are metals and from the metalloids to the right are non-metals

Question 19

What are metalloids?

Answer 19

Half metals
They are brittle, not malleable nor ductile, semi conductors of heat and electricity and are all solid at room temperature

Question 20

Question 21

What are alkali metals?

Answer 21

Found in group 1
Highly reactive to water and air, stored under paraffin, soft, don’t occur freely in nature

Question 22

What are alkali earth metals?

Answer 22

Found in group 2
Alkali solutions in water, reactive, stored in the earths crust, don’t occur freely in nature

Question 23

What are transition metals?

Answer 23

38 elements, groups 3-12, typical metals, split into main and inner transitions

Question 24

What are halogens?

Answer 24

Group 17 (7 valence electron)
Non-metal, reactive, all 3 states of matter, carcinogenic, unpleasant smell

Question 25

What are noble gases?

Answer 25

Group 18 (8 valence electrons)
Rare/inert gases
