In which orbital does an electron in a bromine atom experience the greatest effective nuclear charge?
asambeis [7]

First let us determine the electronic configuration of Bromine (Br). This is written as:

Br = [Ar] 3d10 4s2 4p5

 

Then we must recall that the greatest effective nuclear charge (also referred to as shielding) greatly increases as distance of the orbital to the nucleus also increases. So therefore the electron in the farthest shell will experience the greatest nuclear charge hence the answer is:

<span>4p orbital</span>

A compound has a molar mass of 86.0 g/mol and an empirical formula of C3H7 what is the molecular formula
zmey [24]
The formula for the molecular formula is molar mass/ empirical formula

So, the empirical formula of C3H7 is equal to C*3 + H*7 which is equal to 12*3 +  7. Then use the molecular formula = 86 / (12*3+7) = 2

Therefore, the molecular formula is 2 times the empirical formula which is C6H14.
