Students build a model of a lithium atom with different colored marbles. Lithium Model Information Number of Marbles Blue (protons) 3 Green (neutrons) 4 Red (electrons) 3 Based on the chart, which marbles should the students place in the nucleus of their lithium atom model?(8th grade science)

Blue and Green marbles

Explanation:

We have been given that:

       Number of Marbles:

  Blue(Protons)  = 3

  Green(Neutrons)  = 4

   Red (Electrons)  = 3

The marble that should be placed in the nucleus of a lithium atom  = ?

Solution:

The nucleus of an atom is made up of protons and neutrons.

Protons are the positively charged particles in an atom.

Neutrons do not carry any charges.

  So;

The marble in the nucleus are the Blue and Green marbles.
