The big bang produced all of the hydrogen that exists in our universe in a matter of minutes. overtime, protons began to fuse with the hydrogen atoms. which of the following best explains what adding protons does to an atom?

the atom will form a compound.

the atom will be the same element with a different mass.

the atom will be the same element with a different net charge.

the atom will become a new element.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."

it is the most commonly accepted one
