12 protons, 12 neutrons, 10 electrons
This is a magnesium Ion. There are 12 protons from the magnesium atom.

Also to know is, what is the atomic number of an atom that has 10 protons 12 neutrons and 10 electrons?

neon

Beside above, what is the relationship between an atom that has 12 protons 12 neutrons and 12 electrons? Magnesium, in its elemental form, has 12 protons and 12 electrons. The neutrons are a different matter. Magesium's average atomic mass is 24.305 atomic mass units, but no magnesium atom has exactly this mass.

Keeping this in consideration, what is the mass number of an atom with 12 protons and 12 neutrons?

Name Magnesium
Atomic Mass 24.305 atomic mass units
Number of Protons 12
Number of Neutrons 12
Number of Electrons 12

What is the charge of an atom with 12 protons and 10 electrons?

If it has 12 protons that means it has 12 units of positive charge and 10 electrons which means 10 units of negative charge. Therefore, net charge = +12+(-10) = +2 ( 2 units of positive charge). Since it has 12 protons that means its atomic number is 12 and we know the element with atomic number 12 is Magnesium (Mg).

Antimony

### What is atomic mass number?

The mass number (symbol A, from the German word Atomgewicht [atomic weight]), also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. The mass number is different for each different isotope of a chemical element.

### How do you determine the number of electrons in an atom?

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

### How many electrons are in an element?

Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons. Electrons are arranged around atoms in a special way.

phosphorus

### What is the smallest subatomic particle?

Quarks represent the smallest known subatomic particles. These building blocks of matter are considered the new elementary particles, replacing protons, neutrons and electrons as the fundamental particles of the universe.

### What is the charge of 10 electrons?

And if there are 10 electrons, there is an electronic charge of −1.602×10−18⋅C .

### What element has 2 electrons neutral atoms?

Of course, since neutral atoms have to have one electron for every proton, an element's atomic number also tells you how many electrons are in a neutral atom of that element. For example, hydrogen has an atomic number of 1.

### What is the charge of an atom?

An atom consists of a positively charged nucleus surrounded by one or more negatively charged particles called electrons. The number of protons found in the nucleus equals the number of electrons that surround it, giving the atom a neutral charge (neutrons have zero charge).

argon

### How many valence electrons are in magnesium?

Answer and Explanation: Magnesium has 2 valence electrons. For the main group elements (not transition metals), the group number tells us the number of valence electrons in

### What is the center of an atom called?

An atom a fundamental piece of matter. An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. The protons and the neutrons make up the center of the atom called the nucleus and the electrons fly around above the nucleus in a small cloud.

### How many neutrons are in the nucleus of an atom with an atomic number of 25?

16. What is the mass number of an atom with 3 protons, 4 neutrons, and 3 electrons? 17. How many neutrons are in the nucleus of an atom that has an atomic mass of 36 and an atomic number of 25?

10 electrons

### What is the charge of a proton?

Proton Charge
While a proton has a charge of +1, or 1e, an electron has a charge of -1, or -e, and a neutron has no charge, or 0e. 1 elementary charge is equal to: 1.602 x 10^-19 coulombs.
