<h3>
Answer:</h3>
12 neutrons
<h3>
Explanation:</h3>
- A neutral atom is an atom that has no charge, which means it has no additional electrons or electrons removed from its energy levels.
- An atom is made up of sub-atomic particles neutrons and protons found in the nucleus and electrons found in the energy levels.
- The number of protons in the nucleus of a neutral atom is known as the atomic number.
- In a neutral atom, the atomic number is equal to the number of electrons as protons are equal to the number of electrons.
- The sum of protons and neutrons in the nucleus of an atom is known as the mass number of an atom.
Therefore;
Protons = Atomic number
Protons + neutrons = Mass number
Thus;
Neutrons = Mass number - protons or
= Mass number - atomic number
In this case;
Atomic number = 11
Mass number = 23
Thus;
Neutrons = mass number - atomic number
= 23 - 11
= 12 neutrons
Answer:
the pH of the solution expresses the concentration of hydrogen ion in the solution. By measuring the pH value of a solution helps us to define the acidity or basicity of the solution. If the pH value in the pH scale is greater than 7 then the solution is basic
