It has 85 electrons, because an element always has the same number of electrons and protons

If element X has 85 protons, then it has 85 electrons. 
No matter what element it is, there will ALWAYS be the same amount of protons as there are electrons. 

By the way, thanks for asking this question. I just learned this yesterday, so it gave me a way to show what I learned.

Define the following terms:
Marrrta [24]

Answer:

a)An endothermic reaction is any chemical reaction that absorbs heat from its environment. The absorbed energy provides the activation energy for the reaction to occur eg Melting of ice, Evaporating liquid water

   b)An Exothermic reaction is a chemical reaction that involves the release of energy in the form of heat or light.eg a spark, flame, or flash), electricity , a battery), or sound , explosion heard when burning hydrogen).

c)By definition an exothermic reaction produces heat as part of it’s process. The heat generated just by being alive is an exothermic process as well. And as such we become aware of when we feel “too cold” or “too hot” and try to either adjust to the conditions we are in, or minimize them, if possible. It is not merely odd, but contrary to intelligent living, that we choose to increase our discomfort and also risk our health by intentionally increasing not only the exothermic reactions we use but also maximize them to our own detriment. In short, the increased use of inefficient exothermic reactions while inexpensive in current evaluations of financial cost are extremely expensive in terms of it’s effect upon living things, including ourselves. It is as though we are choosing our homes to not only be next to a furnace, but as close as possible to the process.
