How many atoms of each element are in this compound? MgBr2
A. 2 magnesium atoms and 2 bromine atoms
B. 2 magnesium atom and 2 bromine atoms
C. 2 magnesium atoms and 1 bromine atom
D. 1 magnesium atom and 2 bromine atoms
Its D..!!...the 2 after the Br means its attached to that element..so read as 2 X Br....there is nothing after the Mg...so that means there ais only one
So therefore its D...
To determine the number of atoms of each element in the compound MgBr2, we need to analyze the chemical formula.
In the compound MgBr2, "Mg" represents magnesium and "Br" represents bromine.
The subscript number after each element represents the number of atoms of that element in the compound.
Therefore, the correct answer is:
D. 1 magnesium atom and 2 bromine atoms
