An atom does not have to have equal numbers of protons and neutrons.
The numbers of protons and the numbers of electrons balance; they are equal.
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
Atoms that are neutral must have equal numbers of protons and electrons. This is because protons have a positive charge and electrons have a negative charge. Thus, for the charge to be neutral, the numbers of these particles must be equal.
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
A neutral atom of beryllium has 4 electrons. In a neutral atom, the numbers of electrons and protons are equal. An element's atomic number is the number of protons.
no
Equal numbers of protons and electrons.
An atom is neutral if the numbers of protons and electrons are equal it's neutral.
In a neutral atom, protons and electrons are always equal.
In any neutral atom, the numbers of protons and electrons are equal.
A neutral atom has equal numbers of elecrons and protons.
The numbers of protons and the numbers of electrons balance; they are equal.
An atom must have the same number of electrons and protons to have a neutral charge.
Assuming you mean the charge of an atom with equal numbers of protons and electrons, the charge of the atom would be zero/neutral.
The number of protons is equal to atomic number; in a neutral atom the number of electrons is also equal to the numbers of protons.
Atoms that are neutral must have equal numbers of protons and electrons. This is because protons have a positive charge and electrons have a negative charge. Thus, for the charge to be neutral, the numbers of these particles must be equal.
The negative charge of the electrons equals the positive charge of the protons in a neutral atom. In other words, the numbers of electrons and protons are equal.
