How do you work out the protons and electrons for an element?

Answer 10

By using the atomic number (bottom left number)

Question 11

How do you work out the number of neutrons for an element?

Answer 11

Mass number minus the atomic number

Top and number minus the bottom hand number

Question 20

What did Mendeleev do to the known elements in 1869?

Answer 20

He arranged them according to their properties to make a table of elements

Question 21

Why did Mendeleev leave gaps in the table of elements?

Question 22

Where are the metals and non-metals on the periodic table?

Answer 22

Metals (Left⬅️)

Non-Metals (Right➡️)

Question 23

What are the periods of the periodic table?

Answer 23

Rows on the table where elements in order of increasing atomic number

Question 24

What are the groups of the periodic table?

Answer 24

Columns, elements in the same group have similar properties due to them having the same number of electrons in the outer shell
