Which other elements contain the same number of atomic shells as sodium written as the chemical symbols?
The elements of period 3 has same number of shells as sodium. These elements are Mg, Al , Si, P , S, Cl and Ar.
What metal has an atomic number 12?
Mg- Magnesium
How many electrons and protons are present in Mg 2?
ans 12 atomic no. of Mg is 12 and in Mg2+ there is a lose of only 2 electrons so no. of protons shall be unchanged.
What does the number 24.305 represent for magnesium?
That is the average atomic mass for Mg.
How do you find number of electrons in periodic table or how do you calculate the number of electrons?
A neutral atom has the same number of electrons as it does protons. The atomic numbers on the periodic table for each element are the number of protons. So, look up the element on the periodic table, note its atomic number, and you will then know the number of protons and electrons in a neutral atom of that element. For example, magnesium (Mg) has atomic number 12. So a neutral Mg atom would have 12 protons and 12 electrons.

Is mg an atomic element?
Yes, Mg is Magnesium, it is number 12 on the periodic table
What is the atomic number of 12?
An atomic mass of 12 means carbon, and its atomic number is 6.
How many electrons and protons are present in Mg 2?
ans 12 atomic no. of Mg is 12 and in Mg2+ there is a lose of only 2 electrons so no. of protons shall be unchanged.

What the atomic mass and the mass number of Mg?
The atomic number of magnesium is 12 and the mass number is 24.305 use the Periodic Table it gives you all the info you need :D
How do you calculate the number of moles in 4.637 grams in Mg?
For this you need the atomic mass of Mg. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.4.637 grams Mg / (24.3 grams) = .191 moles Mg
What is the mass in grams of 1.501023 atoms Mg?
This can be found using one of the most important constants for chemistry: Avogadro's number. According to wikipedia, the standard atomic weight of magnesium is 24.3050 grams per mole. Using Avogadro's number, we know there's 6.0221415 × 1023 atoms per mole, so if you divide the standard atomic weight of magnesium by Avogadro's number, you can get number of grams per atom of magnesium (i.e. the mass of a single magnesium atom in grams). (24.3050 g/mole) / (6.0221415 x 1023 atoms/mole) = 4.03564 g/atom
In the periodic table which atom has a mass of 24?
Magnesium (Mg) is the nearest with a mass of 24.3050
