Year 10: Trends in the periodic table

The group an element is in indicates

• how many electron shells it has

• how many valance electrons it has

• nothing interesting

• that Mendeleev was smart cookie

The period an element is in indicates

• how many electron shells it has

• how many valance electrons it has

• nothing interesting

• that Mendeleev was smart cookie

Atomic radius refers to..

• the distance from the nucleus to its outermost shell

• the distance from one side of the atom to the other

• the distance between two bonded atoms

• the distance between electrons in the same shell

The atomic radius increases as you

• go down the periods in a group

• go up the periods in group

The atomic radius decreases as you go from the

• left side of the periodic table to the right

• right side of the periodic table to the left

The elements with the largest atomic radius would be in the

• top left corner of the periodic table

• top right corner of the periodic table

• bottom left corner of the periodic table

• bottom right corner of the periodic table

The atomic radius changes in elements of the same group because

• they have different numbers of electron shells

• they all have different numbers of valance elenctrons

• they have increased number of neutrons

• the electrons become less negative

The atomic radius changes in elements of the same period because

• they have increasing numbers of protons

• they all have different numbers of electron shells

• they have increased number of electrons

• the proton become more positive

A redox reaction involve...

• an exchange of electrons

• a change from solid to liquid

• gaining or losing protons

• valance shells bonding together

Metals typically want to

• gain electrons

• lose electrons
