Question

Hydrogen has one proton in it's nucleus but exists as three isotopes.

One isotope has no neutrons. One has one neutron, and one has two neutrons.
How would they be identified using isotope notation?

PLEASE HELP!

Answer 1

The isotope with no neutrons is H1.

The isotope with 1 neutron is H2.

The isotope with 2 neutrons is H3.

Step-by-step explanation:

Just did the assignment.

The answer is the same as the one above, just without all the fancy stuff.

You know, more simple, more like a student would write!

Answer 2

The Isotope Notation occur by adding the Superscript showing Mass Number and Subscript showing Atomic Number to the Left of the Element Symbol.

Example,

ᵇₐX

Where;
b = Mass Number
a = Atomic Number
X = Symbol
For Hydrogen Isotopes:

1) Protium: 1 Proton , 0 Neutron

¹₁H

2) Deuterium: 1 Proton , 1 Neutron

²₁H

3) Tritium: 1 Proton , 2 Neutron

³₁H
