It is NOT greater. It is smaller. This is because the Hydrogen ion has lost its electron from the atom and is thus smaller. The hydrogen ion is a proton.

Why is the size of an ion greater than its parent atom?
Only the anion is greater than the atom because gained an electron.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
the number of helium and hydrogen atoms is the same
Is a hydrogen atom bigger smaller or the same size as an oxygen atom?
Hydrogen atoms are the smallest known elements, and therefore smaller than oxygen atoms (according to atomic weight and atomic mass).
Why are heavy atoms are not appreciably larger than the hydrogen atom?
My theory to why heavy atoms are not appreciably larger than the hydrogen atom is supposedly because that gases can expand and so that hydrogen is a gas, it is larger though if hydrogen were compressed, it should grow appreciably smaller than heavy atoms. Also to make that test fair you would have to make the heavy atom at its gas state so that then you could see the true, fair differ in size between a hydrogen and heavy atom.
What property of oxygen makes it share electrons unequally with hydrogen atoms?
Oxygen atoms have a greater electronegativity than hydrogen atoms. Electronegativity is the ability of an atom in a molecule to attract electrons to itself.
Is the mass of a hydrogen atom 16 times greater than an oxygen atom?
No, it is inverse.
Why is the size of an ion greater than its parent atom?
Only the anion is greater than the atom because gained an electron.
Can the electron in the ground state of hydrogen absorb a photon of energy 13.6eV and greater than 13.6eV?
yes , the electron in the ground state of the hydrogen atom will absorb a photon of energy 13.6ev but not greater than 13.6 ev . because 13.6 ev is the energy which excites the hydrogen atom
Is the atomic size of magnesium atom greater than that of be?
If by Be you mean beryllium then yes.
An atom of helium has a mass about four times greater than that of an atom of hydrogen Which choice makes the correct comparison of the relative numbers of helium and hydrogen atoms in equal masses o?
the number of helium and hydrogen atoms is the same
Why the chlorine does not form hydrogen bond as the nitrogen do in spite the chlorine is more electronegative than nitrogen?
Size of Cl atom is bigger than size of N atom. Electronegativity difference is .12 which is negligible.
What kind of charge is found on the oxygen atom of polar water molecule?
In a water molecule, the oxygen atom shares electrons with two hydrogen atoms, but it does not share equally since it has a stronger attraction for electrons than the hydrogen atom does, and the electrons therefore have a greater probability of being close to the oxygen nucleus than to the hydrogen nuclei. As a result, the oxygen atom has a negative charge. The hydrogen atoms are positively charged.
Is a hydrogen atom bigger smaller or the same size as an oxygen atom?
Hydrogen atoms are the smallest known elements, and therefore smaller than oxygen atoms (according to atomic weight and atomic mass).
What makes an iron atom have a greater mass than an aliminium atom?
The amount of protons in the nucleus of an iron atom is greater than in that of an aluminum atom.
Will kilogram of hydrogen contain more atoms then kilogram of lead?
Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.Yes, because each hydrogen atom has less mass than each lead atom.

Do atoms share pairs of electrons equally?
No. They reason it is polar is because one side is slightly positive and the other slightly negative. For this to happen, there needs to be unequal sharing of electrons. One atom will have a higher electronegativity than the other, and will naturally "keep" the electrons longer. So that atom will be slightly negative for having held onto the electron, creating a polar bond.
