Isotopes RAM Balancing Nuclear Equations

The letter ‘Z ‘represents, while using notations to write elements to represent the number of protons, neutrons and electrons is/are

A beta particle is a/an

If the relative atomic mass of Br is 78.9183 what is its mass number

The number of neutrons in Pu-238 is

Determine the number of protons, neutrons, and electrons in the following isotopes:

atomic number 9, mass number 18, charge of 1−

When balancing nuclear reaction the following reasoning is used.

1. Both the reactants and products the mass number should be same
2. Both the reactants and products should have the same atomic number

The number of neutrons in U-239 is

Bromine has two isotopes, Br-79 and Br-81, whose relative atomic are masses 78.9183 u and 80.9163 u and abundances are 50.69% and 49.31% Calculate the relative average atomic mass of Br based on these experimental results.

An alpha particle is a/an

The letter ‘A ‘represents while using notations to write elements to represent the number of protons, neutrons and electrons is/are
