what is neutral atom?

the charge on a proton is equal in magnitude and opposite in sign to the charge on a electron.

Therefore if an atom has the same number of electrons as it has protons, it is neutral. Otherwise it is called an "ion".

The charge of this atom is: a. 0, this is a neutral atom b. -3 c. -1 d. +1 e. +3

A neutral atom is an atom that has an equal number of protons and electrons. In other words, the positive charge from the protons is balanced by the negative charge from the electrons, resulting in a net charge of zero. This is why a neutral atom is not negatively or positively charged.

To determine if an atom is neutral, you need to know the atomic number and the number of electrons. The atomic number is the number of protons, which can be found on the periodic table. The number of electrons is usually the same as the number of protons in a neutral atom.

For example, consider the element hydrogen. Its atomic number is 1, which means it has 1 proton. A neutral hydrogen atom will also have 1 electron, since the positive charge of the proton is balanced by the negative charge of the electron.

In summary, a neutral atom is one that has an equal number of protons and electrons, resulting in a net charge of zero.
