Yes. Fusion gives off energy, and according to Einstein's equation E=mc^2, with less energy comes less mass.

What do atoms of elements in the same group of periodic table have in common?
The atoms of the elements in the same group have the same number of valence electrons. This means that they react with other elements in a similar way. For example group 1. All the atoms in group 1 react with water and oxygen, so they have to be kept in paraffin-oil. Another example is group 18. They don't react with anything. The atoms of the same row have the same electron shells.
Why do atoms with the same number of valence of electrons have similar chemical properties?
Because atoms with the same number of valence electrons react in similar ways with other elements.
When two atoms of the same nonmetal react they often form a.?
They often form a diatomic molecule.
When 2 atoms of the same nonmetal element react they form what?
You think probable to diatomic molecules but these are not formed by a reaction.
Why are all atoms of the same type different?
The atoms may be slightly different in shape or size etc. however if they are all of the same type they will all behave and react in the same way. Eg. Two atoms of Frankium may be different in the ways I have described but their chemical properties, behaviour and reactivity are the same.
When sodium chloride and hydrochloric acid react then why sodium hydroxide do not formed?
The reaction is: NaOH + HCl = NaCl + H2O HCl and NaCl cannot react, the anion is the same.
Is the number of mole remain same if you add distilled water?
Yes, the number of moles will remain the same as long as the chemical does not react with water.
Does Na plus react with water the same way as neutral Na?
No. Salt (NaCl) dissolves in water and the (Na) in it does not react with the water as would metallic sodium.

Why two samples of the same pure substance react the same way?
Because they are composed of the very same atoms. There is no difference between their composition, and hence there can be no difference in the way they react. Atoms of the same element have no personalities or individuality; they will always behave the same (given all other conditions are also equal).
Why do atoms with the same number of valence of electrons have similar chemical properties?
Because atoms with the same number of valence electrons react in similar ways with other elements.
Why do certain atoms react with other atoms?
since not all atoms have same no.of electronic configuration they try to attain an octet sharing electrons each other
When two atoms of the same nonmetal react they often form a.?
They often form a diatomic molecule.
When two atoms of the same nonmetal react the often form an?
Diatom via a covalent bond
Does the equation 2 Na plus Cl equals 2 NaCl have the same number of atoms on both sides?
No. There are 2 Na atoms being added to 1 Cl atom.
Does the size of atoms increase remain the same or decrease from the top to the bottom of a group of elements?
yes
Is Forming a mixture a chemical change?
No. The components of the mixture remain the same. They do not react chemically with one another.
