Section One= Properties And Structures

Question 1

Physical reactions

Answer 1

No new substances formed

Mostly the same properties

Question 2

Signs of chemical reaction

Answer 2

New substance
Bubbles of gas
Colour change 
Temperature change
Electricity produced
Light or sound produced

Question 3

Isotopes

Answer 3

Atoms of same element
Different mass number
(Number of neutrons)

Question 4

Prefixes

Answer 4

Four=tetra
Five=penta
Six=hexa

Question 5

Mass spectroscopy

Answer 5

Find mass of atoms and molecules
Converts them into ions, so they can move about
And be manipulated by external electric and magnetic fields

Question 6

Essential functions of a mass spectrometer

Answer 6

1. Small sample is ionised into cations by loss of electrons
2. Ions sorted and separated according to mass and charge
3. Separated ions measured, results displayed on charts

Question 7

Chemical reaction

Answer 7

New substance produced

Different properties
