The number of electrons and protons in a neutral atoms must always what?
#of electrons and # of protons is EQUAL in a neutral atom
What must be equal in a neutral atom?
Protons and electrons must be equal in a neutral atom because protons and electrons have equal but opposite charges.
If a neutral atom has 8 protons it must have how many electrons?
The atom must have 8 electrons to make it have a neutral charge
How many protons and electrons must an element have to be neutral?
zero
What must always be the same in a neutral atom?
To have a neutral atom, the atom must have the same amount of protons, neutrons, and electrons inside of it.
What must be equal for an atom to have a neutral charge?
I think that for an atom to have a neutral charge, it must have the same amount of protons and neutrons. Otherwise its a ion. Check it up on Google just to be sure. Hope I could help :)
What must be true about its number of electrons for an atom to be neutral?
The atom must have equal number of proton and electron to neutral.
If an atom has 19 protons and 20 neutrons how many electrons would it have?
Electrons carry a negative charge and protons carry a positive charge. Therefore, if an atom is to be neutral it must have equal numbers of protons and neutrons. Consequently, if an atom has 19 protons and is neutral it must have 19 electrons.
What must a neutral atom with four protons contain?
A neutral atom must contain an equal number of electrons because it is a neutral atom.
What does the number of protons in a atom equal?
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.
In an atom the number of electrons must be the same as the number of?
protons, because the protons are positive and the electrons are negative so to have a neutral atom the protons and electrons must be balanced
How many electrons in a neutral atom of Xenon?
The atomic number of Xenon is 54. This means the atom contains 54 protons. In order to form a neutral atom, the positive charge from the protons and the negative charge from the electrons must cancel out. In order to be neutral the atom must have 54 electrons.
