Atoms that are neutrally charged will have the same number of protons as electrons, because one proton will cancel out one electron. To achieve a net charge of 0, 12 protons must be countered with 12 electrons.

∙ 16y agoThe atomic number is simply the number of protons in an atom - so in this case it would be 12. The atom is magnesium. It's usual Atomic Mass is 24 and because a proton and a neutron both weigh 1 we know that it probably also has 12 neutons.

∙ 16y agoIf it is a neutral atom, it has 12 electrons also.

∙ 15y agoFirst of all 2 electrons would in the first shell which leaves 10. Then 8 electrons in the second shell which only 2 electrons left in the outer shell.
Wiki User
∙ 11y ago12 electrons balance the charge of the 12 protons.
Wiki User
∙ 13y agoIf you mean "atom" rather than neutron, the answer is 12.
In a neutral atom number of protons = number of electrons
Wiki User
∙ 13y agoIt will have 12 electrons; atoms have the same number of electrons as they have protons.

How many protons neutrons and electrons are there in a neutral atom of 113In (indium's-113)?
49 protons, 64 neutrons and 49 electrons.
What does the atomic number tells you?
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
How many electrons is there in boron if there is a atomic number or 5 and atomic mass of 11?
All you need is the atomic number, which gives the number of protons, in this case, 5. In any neutral atom the number of electrons is the same as the number of protons. So any neutral boron atom will have 5 electrons.
What is a charge in an atom?
An atom can either have a positive or negative charge, and a charged atom is called an ion. If an atom loses an electron to another atom, it becomes a positive ion. If an atom gains an electron, it becomes a negative ion.
How many valence electrons are in one neutral atom of hydrogen?
1
How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
If a neutral sodium atom has 11 protons how many electrons does it have?
If a neutral atom of sodium has 11 protons, it will have 11 electrons also.
What are there as many of as electrons in a neutral atom?
protons
How many electrons do atoms need to be neutral?
It depends entirely on what type of atom it is. (Neutral atom is redundant. A "non-neutral" atom is referred to as an ion) If it is an atom of carbon, for example, there are 6 electrons. Silicon, on the other hand, has 14 electrons.
An element has an atomic number of 30 how many protons and electrons are in a neutral atom of the element?
It will have 30 protons and 30 electrons if the atom is neutral.
How many protons and electrons does a neutral atom of chromium have?
24 protons and 24 electrons
How many electrons and protrons in a neutral atom of carbon?
A neutral atom of Carbon has 6 protons and 6 electrons
How many protons electrons does it have?
A "atom" which by definition is electrically neutral, has the same number of electrons as it has protons.
How many electrons and protons are in carbon?
A neutral carbon atom has 6 protons and 6 electrons.
An atom has 15 protons and 18 neutrons How many electrons does it have?
If the atom is neutral, then it will have 15 electrons to balance the 15 protons.
How many electrons does beryllium have in all?
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.
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
