S2- the sulfide ion
I have no idea what you mean by "mole atom". There isn't a specific symbol for a mole of something. If you simply mean "how would you write '1 mole of sulfur' using standard chemical symbols and abbreviations", it would be 1 mol S. Sulfur doesn't actually just come as "S", it's usually S8, but people typically don't worry about that. (It also comes in long chains and ... when hot enough to be gaseous ... S2).
Br- ion will have 8 valence electrons. So to write the Lewis structure, write the symbol Br, with 8 dots around it. Each dot will correspond to one electron.
the number of protons stay the same in every element (i think). So the number of protons is the atomic number. Therefore, this is tungsten (W). The electrons and nuetrons are the only thing that change.
Polonium is a Group 16 element in the p-block of the periodic table. It has a valence shell of 6s26p4, so it has six valence electrons like all of the elements of Group 16 (16-10=6 valence electrons). To write the Lewis dot diagram for polonium, write the symbol for polonium, Po. Then place one electron on each side of the symbol, then place another electron on two sides. You should have two electrons on two sides of the symbol, and one electron on two sides of the symbol. The total number of electrons should be six.
Symbol equations for reactions are written using chemical formulae.
. . : Ar : . . Write Ar, the symbol for argon and then write four electron pairs (or eight electrons) around the symbol.
The term "scientific notation" is used for a method to write very large (or very small) number.The chemical symbol for sulphur is "S".
find the difference between the number of electrons and protons, and then find whether protons(+) or electrons(-) are more abundant. if the difference was 2, for example, and there were (2) more protons than electrons, the charge would be written as: chemical symbol 2+

The chemical symbol of sulfur in equations is S. However, the real chemical formula is S8, so basically 8 atoms of sulfur react to become one molecule. S8 has a crown shape with three spikes on top and two spikes on the bottom. It is too much a bother to write S8 and balance it so we write S in equations.
Br- ion will have 8 valence electrons. So to write the Lewis structure, write the symbol Br, with 8 dots around it. Each dot will correspond to one electron.
You should have the symbol on your keyboard; >

Ag is the nuclear symbol for silver.
show two wrong ways to write the symbol of calcium
aluminums symbol is Al. Bromines symbol is Br. Because bromine is the nonmetal the ending changes to -ide- which makes it bromide. Aluminum has 3 valence electrons and bromine has -1. that makes the formula..... Al^3 Br =) hope it helped
The isotope carbon-12 can be represented as 12C where the '12' is written in superscript. If you want to just represent carbon not as a isotope but as an element, you can just write its chemical symbol C. Carbon-12 has 6 protons, 6 electrons and 6 neutrons.
