Anitride ion has 7 protons, 8 neutrons, and 10 electrons. what is the overall charge on this ion?

The overall charge on this ion is -3.

Solution:

Protons : These are the subatomic species which carries positive charge.

Electrons: These are the subatomic species which carries negative charge.

Neutrons: These are the subatomic species which doesn't carry any charge.

The net charge on the ion will be = (number protons)(charge carried by the protons.) + (total number of electrons)(charge carried by the electrons)

Numbers of proton = 7

Numbers of electrons = 10

So, net charge on the nitride ion =

it's c. elements are placed in rows based on how may valencies electrons have.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
