4 Isotopes are atoms of the same element with the same number of
protons and
(0.5 Points)
O a different number of neutrons.
a different number of electrons
a different number of molecules
the same number of neutrons
​

Achange in the number of neutrons in an atom will change an blank . when the number of protons changes in an atom, a new element will form.

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
