this is the bohr model of an atom or ion. using the periodic table, complete the sentences. this bohr model…

Explanation:

Step1: Count protons

Count the number of yellow - colored protons in the nucleus. There are 12 protons. The atomic number (Z) is equal to the number of protons. Looking at the periodic table, the element with atomic number 12 is magnesium (Mg).

Step2: Determine mass number

The mass number (A) is the sum of protons and neutrons. Count the number of grey - colored neutrons and yellow - colored protons in the nucleus. There are 12 protons and 12 neutrons, so $A=12 + 12=24$.

Step3: Determine charge

Count the number of electrons (blue dots). There are 10 electrons. The charge of an ion is given by the difference between the number of protons and electrons. Charge $=12-10 = + 2$. Since the number of protons is greater than the number of electrons, it is a cation.

Answer:

This Bohr model represents a cation of the element magnesium. It has a mass number of 24 and a charge of + 2.
