Please please please please help

Answer 1

Answer:

Atomic #: 82

Mass #: 206

Charge: 4+

# of protons: 82

# of electrons: 78

# of neutrons: 124

Explanation:

Atomic #: look at the bottom left #, it's always the atomic #.

Mass #: look at the top left # it's always the mass #.

Charge: they give you the charge which is shown on the upper right of the element.

# of protons: is the atomic #

# of electrons: also the atomic # minus 4 bc the charge is a positive 4, indicating that some electrons 'left'.

# of neutrons: 206 (mass # is protons + neutrons) minus 82 (atomic#) which is 124.
