What will be change in absolute atomic mass if 1 amu is defined as 1/24 of 1 atom of c-12
A) DOUBLED
B) QUADRUPED
C) NO CHANGE
Answers
Answer:
An atomic unit of mass is defined as accurately 1/12 the mass of a carbon-12 atom. The carbon-12 atom has six neutrons and six protons in its nucleus. The atomic unit mass is symbolized as amu.
1 amu = Average of the proton rest mass and the neutron rest mass.
1 amu = (Mass of 1 126C atom)/12
1amu = (1.994 x 10-23)/12
1amu = 1.662 x 10^-24g 0r 1.662 x 10^-27kg.
Answer
1amu = 1.662 x 10^-24g 0r 1.662 x 10^-27kg.
Answer:
Atoms are the basic building blocks of all matter. Ionizing radiation can come from unstable (radioactive) atoms or it can be produced by machines. As unstable atoms decay and attempt to become stable, the nuclei release energy in the form of ionizing radiation (alpha particles, beta particles and gamma rays). The energy released is called ionizing radiation because it has enough energy to knock tightly bound electrons from the atom’s orbit. This causes the atom to become a charged ion.
