so I have a set of fill in the blanks for symbol, atomic number, mass number, protons, neutrons electrons and charge.
Protons: 6
Neutrons: 8
Electrons: 2
I said the atomic number was 6, the mass number was 12, and the charge was +4. The only thing I was unsure of was the symbol. I know the element is Carbon and that in the upper right hand corner it should say +4, and I know in the upper left hand corner it should say twelve, but I'm not sure about the bottom lefthand corner. What is the rule for that corner?
Thanks ~Emmyna
Bottom left corner is the atomc number, for C that is 6, the atomic number. The upper left corner is the mass number. The upper right corner is the charge and the lower right corner is the number of atoms, for example H2. By the way, the charge on carbon atoms is zero if it is not combined with anything. Any element is zero in the uncombined state. C usually has a valence of +4.
The symbol is an abbreviation of the element's name. In this case, the element is Carbon, which is commonly represented by the symbol "C". The bottom left-hand corner represents the mass number, which is the sum of protons and neutrons in the nucleus of the atom.
To determine the mass number, you can add the number of protons and neutrons together. So, if the number of protons is 6 and the number of neutrons is 8, you would simply add them to get a total mass number of 14.
Therefore, the complete filled-in information for Carbon would be:
Symbol: C
Atomic Number: 6
Mass Number: 14
Protons: 6
Neutrons: 8
Electrons: 2
Charge: +4
I hope this helps! Let me know if you have any more questions.
