Chlorine is a group 17 element and has the highest electronegativity among the elements given.
A covalent bond is likely to be polar when the atoms involved have different electronegativities, causing an uneven sharing of electrons. This results in one atom having a partial negative charge and the other a partial positive charge, leading to a polar covalent bond.
Protons and Electrons. Furthermore this is true of ALL atoms not "most".
unstable atoms
Most hydrogen atoms don't contain any neutrons. Deuterium atoms are hydrogen atoms with one neutron each, and tritium atoms are hydrogen atoms with two neutrons each, but most hydrogen atoms are protium atoms, with no neutrons at all. All other atoms in the universe except protium contain at least one neutron each.
negatively charged and takes up most of the atoms space Takes up most of the atoms mass and is negatively charged
Carbon and hydrogen atoms.

Solids are made of atoms. In fact, so are most things.
The halogens are most electronegative atoms in their respective periods.
Most atoms are found combined in molecular or ionic substances. Only a few, like oxygen and nitrogen in air are free from other atoms, or gold which is free from others as a solid.
