Which of the following best describes how an atomic property is used in the treatment of cancer? A
A stable atom that absorbs gamma rays is used in radiation therapy to treat cancer.

B
A stable atom that emits gamma rays is used in radiation therapy to treat cancer.

C
An unstable atom that absorbs gamma rays is used in radiation therapy to treat cancer.

D
An unstable atom that emits gamma rays is used in radiation therapy to treat cancer.

the atomic number of magnesium is 12. its nucleus must contain 12 protons and no electrons. the atomic number of an atom is determined by the number of protons.

magnesium is an electrolyte injection commonly used to treat low magnesium levels in your blood. it is also used to prevent or control seizures in women with preeclampsia or eclampsia.

the earth is thought to have been formed about 4.6 billion years ago by collisions from a cloud of hydrogen, helium, rock, ice and other materials. these were pulled together by gravity to form objects in and around earth like- asteroids and small early planets called planetesimals.

so, the best possible answer to this question will be option d- to harden materials to form different parts of earth’s layers

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers

hope it ,
