What does the nucleus of an atom contain?
Protons and Neutrons
1 of 20
What is the mass and charge of a neutron?
Mass - 1 Charge - 0
2 of 20
A forensic scientist carries out a flame test to identify a metal. The scientist sees a lilac flame. Which metal does this indicate?
Potassium (K)
3 of 20
Why does each elemnt produce a different line spectrum?
As each element has a different electron arrangment
4 of 20
What can line spectrums be used for?
Identifying new elements
5 of 20
What feature of atoms determines the order of the periodic table?
Proton number
6 of 20
What are the rows in the periodic table known as?
Columns
7 of 20
What is significant about the properties of elements in the same group?
Having the same amount of electrons on the outer shell
8 of 20
How many electrons can the first shell of an atom hold?
Two
9 of 20
Which group are alkali mentals?
Group 1
10 of 20
As you go dow2n the group of alakali metals, do they become more of less reactive?
More reactive
11 of 20
Give details of the reaction of alakli metals with water
It fizzes and produces a 'squeaky pop'
12 of 20
How does the reactivity of the group 7 elements change as you go down the group?
Gets less reactive
13 of 20
Atoms of group 7 tend to go around in pairs. What word describes this type of molecule?
Diatomic molecules
14 of 20
Describe the appearence of chlorine at room temperature
Dense green gas
15 of 20
Describe the consequences of corrosive symbol
Attacks and destroys living tissue
16 of 20
Name three common hazard symbols
Possibilities: Oxidising, highly flammable, toxic, harmful, irritant or corrosive
17 of 20
What precautions need to be taken when working with group 7 elements? (and) Why?
They are harmful and should be handled with care because they could be corrosive or toxic
18 of 20
What is ionic bonding?
When atoms loose of gain electrons to form changed particles (called ions)
19 of 20
What kind of atoms like to do ionic bonding? (and) Why?
All the elements in group 6 & 7, as they are keen to add an extra electron to fill the outer shell up
