1. Periodic Table

Question 1

Period

Answer 1

These are the horizontal rows that show the number of shells of electrons an atom has and are numbered from 1 - 7

Question 2

Group

Answer 2

These are the vertical columns that show how many outer electrons each atom has and are numbered from 1 – 7, with a final group called Group 0 (instead of group 8)

Question 3

Metal Characteristics

Answer 3

• Electron arrangement: 1-3 outer shell electrons
• Bonding: Metallic bonding due to loss of electrons
• Electrical conductivity: Good conductor of electricity
• Type of oxide: Basic oxides
• Reaction with acids: Many react with acids

Question 4

Physical Metal Properties

Answer 4

• Usually lustrous (shiny)
• Solid at room temperature (excluding mercury)
• Malleable, can be bent and shaped
• High melting and boiling point
• Ductile

Question 5

Non - Metal Characteristics

Answer 5

• Electron arrangement: 4-7 outer shell electrons
• Bonding: Covalent bonding by sharing of outer shell electrons
• Electrical conductivity: Poor conductors of electricity
• Type of oxide: Acidic oxides (some are neutral)
• Reaction with acids: Usually do not react with acids

Question 6

Physical Non - Metal Properties

Answer 6

• Dull, non-reflective
• Different states at room temperature
• Flaky, brittle
• Low melting and boiling points

Question 7

Why are the noble gasses unreactive (inert)?

Answer 7

They have a full outer shell of electrons.

Question 8

Why do elements in the same group react similarly?

Answer 8

They have the same number of outer shell electrons.

Question 9

Noble gas properties

Answer 9

• Non-metals
• Monatomic (exist as single atoms)
• Colourless and non-flammable gases at room temperature
