MgBr2: It's formed of Magnesium Mg, and dibromide Br2. And since Magnesium is a metal and Dibromide a no-metal, it's more appropriate while naming the substance to remove the "di" from "dibromide". Following the rules for naming compounds, the prefixes "mono", "di", etc... should only be used between 2 nonmetals.
So, the name for MgBr2 is Magnesium Bromide.
Hope this Helps! :)
As you go down the table, more electron shells are added to make the radius larger, but as you go to the right, the protons' attraction increases so the radius actually shrinks. <span>Therefore, according to the trend, Cl has a larger radius because it is lower in the table.</span>
Answer: CL has a larger Atomic Radius.
A molecular formula consists of the chemical symbols for the constituent elements followed by numeric subscripts describing the number of atoms of each element present in the molecule. The empirical formula represents the simplest whole-integer ratio of atoms in a compound.
<span>The overall reaction is as follows:
H2O2 + 2ClO2 => 2ClO2- + O2 + 2H+
Half cell reactions:
</span><span>ClO2 + e- => ClO2-
</span><span>H2O2 => O2 + 2H+ + 2e- </span>
A theory must be supported by many different experiments.
