What is the number of each atom in Mg3N2?
Magnesium nitride contain two nitrogen atoms and three magnesium atoms.
How many neutrons are there in nitride?
Seven from the nitrogen atom, eight from each of the three oxygen atoms, and one more from a metal or group that forms a nitrate salt, for a total of 32.
Why is it called magnesium bromide instead of magnesium dibromide?
The convention of adding number prefixes such as di- and tri- to a compound's name is generally reserved for covalent compounds (carbon dioxide, nitrogen trichloride). Magnesium bromide is an ionic compound, so a different naming convention applies.
What is the atomic number of magnesium- 28?
The atomic number of Magnesium is 12.
This element has the lowest atomic number in group 16?
Nitrogen
What is the number of each atom in Mg3N2?
Magnesium nitride contain two nitrogen atoms and three magnesium atoms.
What is the oxidation number of nitride?
Nitrogen in -3
What is the element N3-?
It is NOT an element, but the Nitride anion. (N^3-).
CaN2 what is the oxidation number of N?
The actual chemical formula for calcium nitride is Ca3N2 and not CaN2. The oxidation numbers are +2 for each calcium and -3 for each nitrogen (as it is nitride ion)
How many nitrogen atoms are in 18.8 g of barium nitride?
Barium nitride is Ba3N2 (from the rules of ionic bonding). Its molar mass is 439 grams/mole (from the periodic table), so 18.8 grams of it is 0.0428 moles (by algebraic direct proportion). Multiply this by Avogadro's number (6.02x1023; the number of particles in 1 mole) and you get 2.58x1022 formula units of barium nitride, and there are 2 nitrogen atoms per formula unit, so double it to 5.16x1022 atoms of nitrogen.
What is the number of moles present in 165 g of magnesium?
The number of moles present in 165 g of magnesium can be easily found using the molar mass of magnesium.40.3044 g/mol165 g (1 mol/40.3044 g) = 4.09 mol
How many neutrons are there in nitride?
Seven from the nitrogen atom, eight from each of the three oxygen atoms, and one more from a metal or group that forms a nitrate salt, for a total of 32.
Name the product of the combustion of magnesium?
The "standard" answer is that if you burn magnesium in air, it will oxidize. The combustion product is magnesium oxide (MgO). But we're not done. It will also combine with nitrogen (air is about 79% nitrogen) to form magnesium nitride (Mg3N2), though it prefers to form the oxide. And yes, magnesium will burn in pure nitrogen. It will also burn in carbon dioxide (CO2) releasing carbon and forming the aforementioned magnesium oxide. Magnesium finds a lot of applications. Only steel and aluminum are more common. For instance, some automotive specialty wheels are fabricated of magnesium alloys (the "mag wheels" of the 60's). Magnesium is difficult to ignite when in the form of, say, a vehicle wheel. But the shavings or the powder can be lit more easily. When they burn, they do so with a brilliant white light. And burning magnesium is difficult to extinguish. Put water on it and it can explode, and it will burn more fiercely in any case. Dry powder or sand should be used to extinguish a magnesium fire. Use the link to one of many YouTube video shorts of a magnesium fire. This one features a firefighter applying water to a burning vehicle without knowing of a certainty what is actually involved. Surprise! Another link is provided to the Wikipedia article on magnesium. Be smart here. Don't be a jackass when conducting any investigations. Think them through and do your homework. The number of "experimenters" who end up in emergency rooms throughout the year is staggering. And some don't get there in one piece. Word to the wise.
What does the charge on the magnesium ion have to do with the number of valence electrons that an atom of magnesium has?
The charge on a magnesium ion is +2. This indicates that the two valence electrons present in a magnesium atom have been donated to form one or two anions of some other element.
How many electrons in a nitrogen ion?
The atomic number of nitrogen is 7. That means that nitrogen has 7 protons per atom, each one having a +1 charge. Assuming that the atom of nitrogen is electrically neutral, there must also be 7 electrons, each of them having a -1 charge, in order for the total charge of the atom to be 0.
Why is it called magnesium bromide instead of magnesium dibromide?

What is balance equation for magnesium plus nitrogen?
Mg+ 2HNO3-->Mg(NO3)2 + H2 Products are Magnesium nitrate and Hydrogen gas.
