Students are completing a table about a particular subatomic particle that helps make up an atom.

A 3-column table with 2 rows. The first row has entries Mass (a m u), location, charge. The second row has entries 1/2,000, nothing, has a charge.

What best explains how they should complete the table?

with “Inside the nucleus,” because the particle is a proton
with “Inside the nucleus,” because the particle is a neutron
with “Outside of the nucleus,” because the particle is a proton
with “Outside of the nucleus,” because the particle is an electron

with “Outside of the nucleus,” because the particle is an electron

Explanation:

The table is best completed with “Outside of the nucleus,” because the particle is an electron.

The particle being described is an electron.

Electrons are negatively charged particles with a mass that is about of protons and neutrons

Mass(a.m.u)                         location                              charge

                             outside of the nucleus                   negative charge

Electrons orbits round the nucleus in distinct energy levels.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

particle   p is an electron and particle q is a neutron
