eg- 1H1, 2H1, 3H1,etc

species having same atomic mass but different atomic numbers is called isobars.

eg- 40Ar18,40Kr19 etc

Answer 2

$\huge{\boxed{\sf{ANSWER-}}}$

$\huge{\boxed{\sf{ISOTOPES-}}}$

=) SUCH ATOMS OF SAME ELEMENT WHICH HAVE SAME ATOMIC NUMBER BUT DIFFERENT MASS NUMBER ARE CALLED ISOTOPES.✔✔

$EX:\:\:\:\:\:\:\:PROTIUM(H)\:\:\:\:\: DEUTERIUM(H)$

$\:\:\:\:\:\:Z:\:\:\:\:1\:\:\:\:\:\:\:\:\:\:\:\:1$ ( SAME)

$\:\:\:\:\:\:A:\:\:\:\:1\:\:\:\:\:\:\:\:\:\:\:\:\:2$

$\huge{\boxed{\sf{THEY\:ARE\:ISOTOPES-}}}$

$\huge{\boxed{\sf{ISOBARS-}}}$

=) SUCH ATOMS OF DIFFERENT ELEMENT WHICH HAVE SAME MASS NUMBER BUT DIFFERENT ATOMIC NUMBER ARE CALLED ISOBARS.✔✔

$EX:\:\:\:\:Ar\:\:\:\:\:K\:\:\:\:\:\:Ca\\Z:\:\:\:\:\:\:18\:\:\:\:\:\:19\:\:\:\:\:\:20\\A:\:\:\:\:\:\:40\:\:\:\:\:\:40\:\:\:\:\:\:40(SAME)$

$\huge{\boxed{\sf{THEY\:ARE \:ISOBARS-}}}$
