Answer 4

Up

Question 5

As you go down group 1 the melting point increases/decreases

Answer 5

Decreases

Question 6

As you go down group 7 the melting point increases/decreases

Answer 6

Increases

Question 7

How are the properties of the transition metals different to the properties of the alkali metals?

Answer 7

Higher melting points
More dense
Stronger and harder
Less reactive

Question 8

What properties are specific to the transition metals?

Answer 8

Elements can have different charges
Form coloured compounds
Can be used as catalysts

Question 9

How is the modern periodic table organised?

Answer 9

Atomic number
Group number corresponds to electrons in outer shell
Period number corresponds to number of shells

Question 10

Why was Mendeleev’s periodic table more accepted than Newland’s?

Answer 10

He left spaces for undiscovered elements

Question 11

How did the discovery of gallium help scientists to accept Mendeleev’s table more?

Answer 11

He left a space for it

The properties he predicted were close to its properties
