Question

this is the bohr model of an atom or ion. using the periodic table, complete the sentences. this bohr model represents an of the element. it has a mass number of and a charge of

Explanation:

Step1: Count protons

Count the number of protons (yellow - + particles). There are 6 protons. The atomic number (number of protons) determines the element. Looking at the periodic table, an element with 6 protons is carbon.

Step2: Count neutrons

Count the number of neutrons (grey particles). There are 6 neutrons. The mass number is the sum of protons and neutrons. So mass number = 6 (protons)+ 6 (neutrons)=12.

Step3: Count electrons

Count the number of electrons (blue - particles). There are 4 electrons. The charge of an atom or ion is given by the number of protons - number of electrons. Charge = 6 (protons)-4 (electrons) = + 2. Since the number of electrons is less than the number of protons, it is a cation.

Answer:

This Bohr model represents a cation of the element carbon. It has a mass number of 12 and a charge of + 2.
