CuSO4, also known as copper(II) sulfate, is an inorganic compound made by combining a copper ion with a charge of positive two and a sulfate anion with a charge of negative two. CuSO4 is used as a fungicide, pesticide an... More »

One Lewis dot structure for a sulfate ion is an S connected by two pairs of dots to two O's, each of which is surrounded by two pairs of dots. The S is connected by one pair of dots to two additional O's. More »

The charge of a strontium ion is +2. The charge of an ion is determined by the amount of electrons compared to the number of protons, so a charge of +2 indicates that the ion has two more protons than electrons. More »

The most common magnesium ion has a +2 charge, which means it has lost two of its original 12 electrons, leaving it with a total of 10 electrons. The atomic number of magnesium is 12, which means that in its stable state... More »
