Question

Define the following terms with one example each


1. Isotopes
2. Isobars
3. Isotones
4. Isosteres

Answer 1

Answer:

ISOTOPES------

Isotopes are the atoms which have same atomic number but different atomic masses.

EXAMPLE---------

chlorine has two isotopes both have same atomic number but different atomic masses

mass of first one is 35 and second is 37.

ISOBARS-------

Isobars are the atoms of different elements having same atomic mass but different atomic number.

EXAMPLE---------

Argon

and Calcium

both have same atomic mass as 40 but atomic number of argon is 18 and Calcium is 20.

ISOTONES------

isotones are the atoms of different element which have

same number of neutrons but different atomic number..

EXAMPLE--------

carbon and nitrogen have same number of neutron that is 8

but atomic number of nitrogen is 7 and atomic number of carbon is 6.

ISOSTERES-----

isosteres are the molecules which have same number of atoms with equal

number of Valence Electrons

EXAMPLE-------

N2O and CO2

both have 16 atoms and same number of Valence Electrons
