It has a lower ionization energy than iodine

Question 5

Atomic radius grows down a group mainly because:

Accepted Answer

a new electron shell is added

Answer

mass increases

Answer

the nucleus gains extra protons that push electrons out

Answer

neutron count sets the size

Question 6

Compared with sodium, magnesium’s first ionization energy is:

Accepted Answer

higher

Answer

lower

Answer

about the same

Answer

exactly twice as large

Question 7

Accepted Answer

proton count

Answer

neutron count

Answer

mass number

Answer

atomic mass to all digits

Question 8

Helium is drawn with the noble gases because:

Accepted Answer

its 1s² shell is closed, so the chemistry is inert

Answer

it has two valence electrons, like beryllium

Answer

IUPAC lists it as a metal

Answer

it forms He²⁺ the way Be forms Be²⁺

Question 9
