Explanation:

Step1: Count Protons

Protons are the positive - charged particles in the nucleus. From the diagram, we can see that there are 5 protons (the + - charged particles in the nucleus).

Step2: Count Neutrons

Neutrons are the neutral - charged particles in the nucleus. From the diagram, we can see that there are 4 neutrons (the non - charged particles in the nucleus).

Step3: Count Electrons

Electrons are the negative - charged particles in the electron cloud. From the diagram, we can see that there are 5 electrons (the - - charged particles in the electron cloud).

Step4: Calculate Atomic Mass

Atomic mass is approximately the sum of protons and neutrons. So, atomic mass = protons + neutrons = 5+4 = 9.

Step5: Determine Atomic Number

Atomic number is equal to the number of protons. So, atomic number = 5.

Step6: Identify Element Symbol and Name

The element with atomic number 5 is Boron, and its symbol is B.

Step7: Determine Ion and Charge

Since the number of protons (5) is equal to the number of electrons (5), the ion is 'no' (neutral atom) and the charge is 0.

Answer:

Protons: 5; Neutrons: 4; Electrons: 5; Atomic Mass: 9; Atomic Number: 5; Element Symbol: B; Element Name: Boron; Ion: no; Charge: 0
