A scientist discovers that an atom with a mass number of 14 contains eight electrons.
According to the scenario, what is the atom's atomic number?

8
14
please help
To determine the atom's atomic number based on the given information, we need to understand the relationship between the number of electrons and the atomic number.
The atomic number of an atom is the number of protons it contains. Since the atom is electrically neutral, the number of protons (which equals the atomic number) is equal to the number of electrons.
In the scenario, it is stated that the atom contains eight electrons. Therefore, we can conclude that the atom's atomic number is also 8.
So, from the given options, the correct answer is "8".
To determine the atom's atomic number, we need to understand the relationship between the mass number and the number of electrons.
The mass number of an atom is the total number of protons and neutrons in its nucleus. In a neutral atom, the number of electrons is equal to the number of protons, known as the atomic number.
In this case, it is given that the atom has a mass number of 14 and eight electrons. Since the atom is neutral, the number of protons (which is the same as the atomic number) will also be eight.
Therefore, the atom's atomic number is 8.
Among the given options, the correct answer is "8."
The atomic number of ANY element is the number of protons in the nucleus. ANY NEUTRAL atom (and I assume this one is neutral) contains the same number of electrons as protons. And how many electrons are there?
As a side note,
mass number = #protons + # neutrons.
If mass number is 14 and atomic number is ???, then how many neutrons are there?
