What charge would an ion have if it had more electrons than protong?
max2010maxim [7]

Answer:

D. It would have a net negative charge

Explanation:

In an atom, there are electrons, protons and neutrons collectively called SUBATOMIC PARTICLES. The charge of an atom is determined by the number of electrons and protons in that atom. A neutral or uncharged atom possess the same number of electrons and protons.

The charge can thus be calculated as follows:

Charge of atom = no. of protons - no. of electrons.

Hence, when the number of electrons in an atom is higher than that of the protons, it means that the atom has gained negatively charged electrons, making that atom have a net negative charge. For example, In an atom that contains 10 protons and 11 electrons, the charge of that atom will be (10 - 11) = -1. The net charge of that atom will be -1, which is NEGATIVE.

Let’s assume that you put a balloon into the freezer. Initially,the balloon had 3.0liters of gas at a pressure of 400kPa and was
EastWind [94]
Here, we should use combined gas law which can be derived from combined gas law, “PV=nRT”. Rearranging, we can get PV/T=nR. Then we can set the two states in the problem together to get

P1V1/T1 = P2V2/T2

Then just plug in and solve algebraically.

Hope this helps
