PERIODIC TABLE TWO

Question 1

HOW DO ALKALI METALS REACT TO AIR?

Answer 1

alkali metals look dull and when cuts are shiny,
when in contact with air they become dull again

Question 2

WRITE A NOTE ON THE ALKALINE EARTH METALS

Answer 2

they are group 2
beryllium
magnesium
calcium
are in this group
all elements in this group have two electron sin their outer shell

Question 3

WRITE A NOTE ON THE HALAGONS

Answer 3

they are group 7
the elements in group 7 electrons in their outer shell
fluorine
chlorine
are in this group
elements in this group are trying to gain an electron because they want a full outer shell

Question 4

WRITE A NOTE ON THE NOBLE GASSES

Answer 4

the elements in group 8 are all gasses and have full outer shells of electrons
helium
neon
argon
are in this grpup

Question 5

WHAT IS IONIC BONDING/

Answer 5

lonic bonding produces a compound that is formed from a metal and a non-metal and is made up of ions. This occurs when one atom loses electrons and another atom gains electrons.

Question 6

WHAT IS COVALENT BONDING?

Answer 6

Covalent bonding produces a compound formed from non-metals in which each atom shares electrons with another atom.

Question 7

WHAT HAPPENS WHEN A METAL AND NON-METAL COMBINED?

Answer 7

When a metal and a non-metal are combined, the resultant compound is called after the name of the metal followed by the name of the non-metal, with its ending changed to '-ide'
eg.sodium+chlorine=sodium chloride
metal non-metal compound

Question 8

COMBINDING METL ATOMS NON-METALS AND OXYGEN

Answer 8

When naming compounds formed by combining a metal atom, a non-metal atom and oxygen, the name of the metal comes first, the name of the non-metal comes next and the ending is '-ate'.
This occurs only when an oxygen atom is present.
For example:
potassium+phosphorus+oxygen
potassium phosphate
