How many atoms of each element are in this compound? MgBr2

What is your problem here? The subscripts (or what passes for subscripts) tell you how many atoms are there.

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

To determine the number of atoms of each element in the compound MgBr2, we need to understand the chemical formula and use the rules of stoichiometry.

In the chemical formula MgBr2, "Mg" represents magnesium and "Br" represents bromine. The number 2 after "Br" indicates that there are 2 bromine atoms present in the compound.

Therefore, the correct answer is:

D. 1 magnesium atom and 2 bromine atoms
