how many atoms and element are there in MgCI2 magnesium chloride
Answers
Answer:
Magnesium chloride, also known as MgCl2, is an ionic compound composed of two elements, magnesium and chlorine. It consists of a magnesium cation denoted by Mg2+ and 2 chlorine anions denoted by Cl–. This makes up a total of three atoms: one magnesium atom and two chlorine atoms. The formula for magnesium chloride is MgCl2, and its molar mass is 95.211 g/mol.
Magnesium is a Group 2 element of the periodic table and has an atomic number of 12. It has two electrons in its outermost energy level and is most stable with a full octet of electrons. Chlorine is a Group 7 element of the periodic table and has an atomic number of 17. It has seven electrons in its outermost energy level and is most stable with a full octet of electrons.
The combination of the two elements in MgCl2 forms an ionic bond, where the magnesium atom donates two electrons to the chlorine atoms. These electrons are then shared between the two chlorine atoms, giving them a total of eight electrons in their outermost energy level, making them stable. The magnesium atom is left with two electrons in its outermost energy level and is also stable.
To conclude, magnesium chloride or MgCl2 is composed of one magnesium atom and two chlorine atoms, making a total of three atoms. The two elements are bonded together through an ionic bond.

Answer:
There are a total of three atoms, in one molecule of MgCl2, which are one Mg atom and two Cl atoms.
Explanation:
In one molecule of magnesium chloride (MgCl2), there are one magnesium (Mg) atom and two chlorine (Cl) atoms.
Mg is a met allic element with an atomic number of 12, which means that it has 12 protons and 12 electrons. Its elec tron configuration is 1s2 2s2 2p6 3s2, which means it has two electrons in its outermost energy level.
Chlorine (Cl), on the ot her hand, is a non-metallic element with an atomic number of 17, which means it has 17 protons and 17 electrons. Its electron configuration is 1s2 2s2 2p6 3s2 3p5, which means it has seven electrons in its outer most energy level.
Therefore, in one molecule of MgCl2, there is one Mg atom and two Cl atoms, making a total of three atoms. These atoms combine to form an ionic compound, where the Mg atom loses two electrons to become a cation with a charge of +2, and the two Cl atoms each gain one electron to become anions with a charge of -1. The resulting compound has the chemical formula MgCl2 and is electrically neutral.
