Atomic Structure And The Periodic Table

Question 1

What are the name of group 0

Answer 1

Noble gases

Question 2

What are the name of group 1

Answer 2

Alkali metals

Question 3

Name of group 7

Answer 3

Halogens

Question 4

Name of 2 and 3 group

Answer 4

Transition metal

Question 5

Noble gases properties

Answer 5

Boiling point increases down the group

They are unreactive because have a full outer shell

Question 6

Alkali metals properties

Answer 6

• Boiling point decreases as go down group as outer electron becomes further away for nucleus more easy to lose
• stored in oil
• low density
• soft

Question 7

Halogen properties

Answer 7

• reactivity decreases down the group
• ## melt and boiling points increase down the group

Question 8

Transition metal properties

Answer 8

• form coloured compounds
• can be used as catalysts
• easily bent
• good conductors

Question 9

Which group when reacted with water produces a metal hydroxide and hydrogen gas

Answer 9

Alkali metals

Question 10

What’s different about halogens than the other groups

Answer 10

Molecules made up of pairs of atoms

Question 11

Explain new lands periodic table

Answer 11

Only 63 elements

In order of atomic weight

Question 12

Explain dimitri Mendeleevs periodic table

Answer 12

Left gaps for undiscovered elements
Placed in groups with similar properties
Used periodic table to predict existence of other elements
In order of increasing atomic number and in order of atomic mass

Question 13

What is the radius of a typical atom

Answer 13

1 x 10^-10

Question 14

What is fractional distillation

Answer 14

Used to separate mixtures which contain components with SIMILAR BOILING POINTS (opposite is simple distillation)
