Explanation / Answer

Ths sun source of energy is nuclear fission

FALSE

EXPALNATION

The Sun ---------ENERGY generates its energy by nuclear fusion

LEAd is required to shiled human against alpha particles

FALSE

EXPALNATION

An isotope often called nuclide in chemistry

true

A chain eaction sustain itself by decreasing the amount of neutrons

true

a standard solution is a solution whose concentration is accurately known

true

c-13----dating

FALSE

14
C), a radioactive isotope of carbon------ Radiocarbon dating

Ionization happens …..with gamma radiation
