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.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
