If you don't eat meat, you can still get your iron. Tofu is a good choice. Or go for beans, like kidney, garbanzo, or white. Food from plants has non-heme iron, which means your body doesn't absorb it as well as the heme type found in meat.
Methane is a compound and therefore does not have any atomic number. It is composed of carbon with atomic number 6 and hydrogen with atomic number 1. Methane is a compound and therefore does not have any atomic number. It is composed of carbon with atomic number 6 and hydrogen with atomic number 1.
For instance, to a first approximation, 1 gram of hydrogen element (H), which has a mass number of 1 (atomic number 1), has 7023602200000000000â 6.022Ã1023 hydrogen atoms. Similarly, 12 grams of 12 C, with the mass number of 12 (atomic number 6), has the same number of carbon atoms, 7023602200000000000â 6.022Ã1023. Avogadro's number is a dimensionless quantity and has the numerical value of the Avogadro constant given in base units.
