The number of atoms in one mole of any substance is measured by Avogadro's number. The value of Avogadro's number is 6.023 x 10 ^23. It is named after scientist Avogadro who proposed this number. 12 grams of carbon-12 represents 1 mole of carbon-12. For this reason, the number of atoms present in 1 mole of any substance is 6.023 x 10 ^23. Therefore, the number of atoms present in 1 mole carbon-12 is 6.023 x 10^23.
(Answer) This unit is the number of atoms in 12 grams of carbon-12 and known as Avogadro's number.
Answer:
I Would bc it's the better opportunity
Se2- has 34 protons and 36 electrons so it gets a 2- charge.
Oil, we are using it too fast for it to regenerate.
A large unstable nucleus becomes tinier and emits an alpha
particle during Alpha decay. 4/2He or the alpha particle that consists of two
protons and two neutrons can be discharged from the nucleus during the disintegration
of radioactive decay. It has a charge of
positive 2.
