He discovered the atom while standing on a beach talking. Although, he thought the atom was like a ping pong ball.
Neutrons are neutral Electron are negative and protons are positive
Answer: Calcium sulfide is a chemical compound having formula CaS. While Calcium sulfide is inorganic compound g fomlaCaSO4.
Explanation:
calcium sulfide is use in preparation of hydrogen sulfide, luminous pain and as a depilatory in cosmetics while calcium sulfate is used as desiccant. calcium sulfides is white material crystallizes in cubes like rock salt while calcium sulfate has three different crystalized forms known as hemihydrate (CaSO4⋅12H2O) , anhydrate (CaSO4) and as gypsum (CaSO4⋅2H2O). hope this explanation will be helpful for you
Polar liquids have both negative and positive ends.
Calcium, which is in Period 2 and has 2 valence electrons, has an ion of Ca 2+
This is because it can give up the two electrons to get a full outer shell.
Nitrogen, on the other hand, has 5 valence electrons. To get a full outer shell, it can either gain 3 electrons or lose 5. Since it is easier to gain 3, Nitrogen usually gains 3 electrons to form a N3- ion.
Even though it is rare, it is possible for Nitrogen to form a positive ion, which is N5+
