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.
An element with 74 protons is tungsten. Because there are only 68 electrons, this creates a net charge of 6+. The chemical symbol is the W with a 6+ superscript.
The symbol would be Am6+
Its Am+6 for the element americium

This is wolfram (W): W(6+).

Here is the isotopic notation for carbon 14. From looking at the isotopic notation, you can find the number of protons, neutrons and electrons in an atom. Protons- The atomic number is 6, so there are 6 protons Electrons- If the atom is neutral the number of protons equals the number of electrons, so there are also 6 electrons Neutrons- The mass number equals the number of protons + neutrons, and 14-6 leaves 8 neutrons 14 C 6
If there are more electrons than protons, then the ion charge is negative. If there are more protons than elections, then the ion charge is positive.
Neutrons need not be considered here. There are 3 more electrons, the negatively charged subatomic particle, than there are protons, which are positively charged. So; 3(-) is the charge on the atom.
This is not an equation but the chemical symbol of the cation: Ba2+.
Chemical Symbol.
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 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.

The chemical symbol of helium is He; the chemical symbol of magnesium is Mg.

. . : Ar : . . Write Ar, the symbol for argon and then write four electron pairs (or eight electrons) around the symbol.
If there are more electrons than protons, then the ion charge is negative. If there are more protons than elections, then the ion charge is positive.
Neutrons need not be considered here. There are 3 more electrons, the negatively charged subatomic particle, than there are protons, which are positively charged. So; 3(-) is the charge on the atom.

Symbol equations for reactions are written using chemical formulae.
Assuming that the questioner intended to write "Cr" instead of "cr", the isotopes indicated are those of the element chromium, whose atomic symbol is "Cr" and whose atomic number is 24. The atomic number is defined as the number of protons in a nucleus of each atom, and the atomic mass number, which precedes the atomic symbol, is defined as the number of protons and neutrons combined. In order to maintain electrical neutrality as is required for any atom, the number of electrons must be the same as the number of protons. From the definition of mass number, it follows that the number of neutrons is equal to the atomic mass number minus the atomic number. Therefore, each isotope named in the question has 24 protons and 24 electrons, but the isotope with mass number 58 has 32 neutrons and the isotope with mass number 63 has 32 neutrons has 39 neutrons.
