What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

Are atoms of nonmetals among the largest atoms?
Atoms of nonmetals tend to be smaller than atoms of metals in the same period.
Are ions of alkali metals larger or smaller than ions of alkaline metals from the same period?
larger
What do all the atoms in the same period have in common?
All member of the same period share the same number of energy levels. The energy levels range from one up to seven.
Why don't atoms simply get larger as you read across the periodic table?
because the no. of shells in the atoms across the periodic table remains the same

What do atoms of the same period have in common?
They all have the same number of energy levels. That's about it.
Could it be that atoms be getting 'larger' but we don't notice because its all the same ratio to us since you heard the universe is expanding?
I am sure that atoms are getting larger. But i know that people do keep record of each atoms that comes.

What is the element in the fourth period whose atoms have the same number of electrons in their highest energy levels that tins atoms do?
bromine, i think

Are ions of alkali metals larger or smaller than ions of alkaline earth metals from the same period?

Are ions of alkali metals larger or smaller than ions or alkaline earth metals from the same period?
larger
Does the electron cloud determine the size of the atom?
More or less, but all atoms are about the same size as each other. You would think that heavy atoms, with many electrons, would be much larger, but they aren’t. The reason is that large atoms have large nuclei with many protons. These exert a strong force on theelectrons, pulling them in closer. So even though there are more electrons in large atoms, they arepulled in closer, leaving the overall size of the heavy atoms the same as for light ones.
