Fill out the Table- Some parts are filled in for you

What changed when you added 1 more electron to the H atom model?

Element Symbol

Net Charge

Mass Number

Atomic Number= Is the identity of an element. If you change this, then you cange what the atom is.

Mass Number = Represents the mass of the atom. It comes from the particles that are located in the dense nucleus in the center of the atom.

An atom becomes charged or an ion forms when an atom is no longer neutral because the number of protons does not equal the number of electrons.

Move the choice to each category that makes the statement true

Electrons
Protons
Neutrons

Atomic Number is the number of __________.
Mass Number is the number of protons + _______________.
An ion (charge) forms when __________ are added or removed from the atom.

Draw or take a screen shot picture from phet simulation to answer.

Why is atom 9 a positive cation? Were electrons gained or lost in order to form the ion?

gained electrons

lost electrons

How would you build a negative ion (anion) for atom 12? Would you need to lose or gain electrons?

lose electrons

gain electrons
