What is Magnesium's charge when it has a complete set of valence electrons?
The overall charge of any atom is 0. This is because the overall charge is number of protons - number of electrons. For every atom the number of electrons is equal to the number of protons so it is 0.
What is the valency number of magnesium?
Valency is not a word... but if you want to know the number of valence electrons that Magnesium has, it is 2. Magnesium's atomic number is 12.
How many valence electrons does a neutral magnesium atom have?
If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
Is the effective nuclear charge equivalent to the number of valence electrons in an atom?
No, the effective nuclear charge is not equivalent to the number of valence electrons in an atom. The effective nuclear charge is the net positive charge experienced by an electron in a multi-electron atom, taking into account the shielding effect of inner electrons. Valence electrons are the electrons in the outermost energy level of an atom that are involved in bonding.
Magnesium protons and electrons?
A magnesium atom has 12 protons, 12 electrons, and 12 neutrons. Protons carry a positive charge, electrons a negative charge, and neutrons have no charge. The number of protons determines the element (in this case, magnesium), while the number of electrons balances the positive charge of the protons to maintain a neutral atom.

How many valence electrons does a neutral magnesium atom have?
If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
Do helium has the same number of electrons in the outer shell as in magnesium?
Yes, helium only has two electrons which makes up its valence electrons (also known as an outer shell) and magnesium also has two valence electrons.
Which has the greater number of valence electrons Ca or Mg?
Both are in the same group; accordingly, they have the same number of valence electrons (2).
Which elements have the same number of valence electrons as beryllium?
For example calcium and magnesium.
What is different in number of shells in magnesium and sulphur?
There are no difference in the number of shells in magnesium and sulphur. Both elements contain 3 shells. However, the total number of electrons in the shells are different. Magnesium has 12 electrons in its shells whereas sulphur has 16 electrons in its shell. In addition, the electrons in the valence shell (outermost shell) are also different. Magnesium has 2 electrons in its valence shell whereas sulphur has 6 electrons in its valence shell.

How many valence electrons are in an ion of manganese that has 5 charge?
5, because the charge indicates the number in the valence orbital (outer shell).
What element has two valence electons?
Here at Afuelscience.com we use this method...the number of valence electrons is the number of s and p electrons in the outermost shell (highest n). The number of valence electrons can also be determined by counting across the period, skipping the transition metals, until the element is reached. It is also the group number. If there is more than one atom, the number of valence electrons is the sum of all the atoms in the molecule or polyatomic ion. For ions, add the value of a negative charge and subtract the value of a positive charge. >> Example 1 How many valence electrons are in the following? # N # H2S # CO32- # NH4+ Solution: # Nitrogen is in group 5A. It has five valence electrons. # Hydrogen has one valence electron, and sulfur has six. The total for the molecule is 2(1) + 6 = 8. # Carbon has four valence electrons; oxygen has six; then two for the charge. 4 + 3(6) + 2 = 24. # Nitrogen has five valence electrons; hydrogen has one, minus one for the charge. 5 + 4(1) - 1 = 8.
What pair what has the same number of valence electrons magnesium and potassium lithium and calcium argon and xenon phosphorus and tellurium?
Argon and Xenon have the same number of valence electrons, both are noble gases (group 18 that have 8 electrons).
