Question

if you change the number of electrons... mass #: stays constant changes charge: stays constant changes atom name (identity): stays constant changes questions) ation, and you must use critical thinkin wards! hallenge 2 element name: element symbol: mass number:

Explanation:

Step1: Recall mass - number definition

Mass number is the sum of protons and neutrons. Changing electrons doesn't affect protons and neutrons. So mass number stays constant.

Step2: Recall charge concept

Electrons are negatively - charged. Adding or removing electrons changes the net charge of the atom. So charge changes.

Step3: Recall atomic identity concept

The identity of an atom is determined by the number of protons (atomic number). Changing electrons doesn't change the number of protons. So atom name (identity) stays constant.

Answer:

Mass #: Stays Constant
Charge: Changes
Atom Name (Identity): Stays Constant
