FREE Expert Solution

We’re being asked to determine the number of electrons, protons, and neutrons in the ion 9Be+


An element can be represented as:


You can determine the identity of the element using its atomic number:

Atomic number (Z): 

represents the identity of the element
reveals the number of protons
in a neutral element:

            # of protons = # of electrons

Mass number (A)

reveals the number of protons and neutrons

            mass number = # of protons + # of neutrons


Given:           9Be+
