Chemistry Staar Review test II 2nd p

What particle is located in the nucleus and has a positive charge?

• Protons

• Electrons

• Neutrons

The atomic number tells us how many protons an element has.

• True

• False

How would you calculate the amount of neutrons an element has?

• Number of neutrons = atomic mass – atomic number (# protons)

• Number of neutrons = atomic mass + atomic number (# protons)

• Number of neutrons = atomic symbol – atomic number (# protons)

• Number of neutrons = atomic mass x atomic number (# protons)

What particle is found OUTSIDE of the nucleus?

• Protons

• Electrons

• Neutrons

Where do you look on a periodic table for an elements symbol?

• The letters (normally the first letter is capitalized and the second is lower case)

• The number at the top of each square

• The number at the bottom of each square

• You cannot find that information out
