There is a charge of +4 on an atom of beryllium.

There is a charge of −4on an atom of beryllium.

There are four neutrons in the nucleus.

There are four protons in the nucleus.

the product of the pressure and volume is also constant

that tool would be a compass

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".

the answer is barium and copper bromide
