Question

One isotope of carbon has 6 protons and 8 neutrons. Which is the correct reference for this isotope?

carbon-2
carbon-6

carbon-8

carbon-14

Answer 1

carbon 14 bcz isotope is represented by the atomic mass.which is the sum of protons and neutrons

Answer 2

well i hope,, u r right ,, i need alot of effort now exams are ahead and don't ask about chem......so difficult

Answer 3

What arrangement is represented in the periodic table?

a repeating pattern of outer electrons
random order for atomic mass
a reverse sequence for the number of neutrons
repeating patterns of isotopes

Answer 4

Going down any standard column of the table gives the number of valence electrons, to a point. Hydrogen, Lithium, etc column has 1 outer electron. Helium and noble gases typically have 8, but Helium has 2, which satisfies a complete "shell" of outer electrons for the first tier. souce yahoo answers, i knew it but i needed a suitable logic

Answer 5

so first one is correct

Answer 6

thats what i thought thanks
