According to the report of US Environmental Protection
Agency, majority of large dose radiation exposure comes from natural background
radiation sources particularly the radioactive gases radon and thoron. This two
gases form when naturally occurring elements decay. However in the case of
man-made sources, the largest dose comes from medical x-rays.
The answer to this one is brittleness ! ;)
Answer:
Z=26, A = 56, charge +3.
Explanation:
The atomic number is represented by Z. Is equal to the total number of protons that the atom has. Z=26.
The atomic mass is represented by A. The number results from the total sum of protons and neutrons of an atom. Both particles have a weight of 1 uma, are in the nucleus and give the mass to the atom.
Mass number (A) = atomic number (Z) + number of neutrons (N)
A = 26 + 30
A = 56
The net charge of the atom can be calculated by subtracting the negative charges from the positive ones. The positive charges come from the protons and the negative ones from the electrons.
26-23=3
This iron ion has a positive charge +3.
