Question

what is meant by atomic mass number explain how to atomic number and mass number of carbon are 6 and 12 respectively

Answer 1

Atomic number of an element refers to the number of electrons or protons present in that element. It is denoted by Z. ... Carbon has 6 protons, 6 electrons and 6 neutrons. So the atomic number is 6 as the number of protons is 6. The mass number is 12 as the sum of protons and neutrons is 12.

Answer 2

Answer:

c.ατσмic мαss ทυмвєr : iτ is τнє sυм σƒ τσταℓ ทυмвєr σƒ ρrστσทs αท∂ ทєυτrσทs ρrєsєทτ iท α ทυcℓєυs.

ατσмic мαss ทυмвєr = ทυмвєr σƒ ρrστσทs + ทυмвєr σƒ ทєυτrσทs.

ατσмic ทυмвєr = ทυмвєr σƒ ρrστσทs = ทυмвєr σƒ єℓєcτrσทs. iτ is ∂єทστє∂ вy ʑ.

мαss ทυмвєr = ทυмвєr σƒ ρrστσทs + ทυмвєr σƒ ทєυτrσทs. iτ is ∂єทστє∂ вy α.

ƒσr єxαмρℓє : cαrвσท ατσм iτs, ทυмвєr σƒ ρrστσท = 6

ทυмвєr σƒ ทєυτrσทs = 6

ทυмвєr σƒ єℓєcτrσท = 6

ατσмic ทυмвєr(ʑ) = ทυмвєr σƒ ρrστσทs = ทυмвєr σƒ єℓєcτrσทs = 6.

мαss ทυмвєr(α) = ทυмвєr σƒ ρrστσท + ทυмвєr σƒ ทєυτrσทs = 6 + 6 =12.
