name the elementwhich has the following numbers of particles:

Question

a.26 electrons,29 neutrons,26 protons
b.53 protons,74neutrons
c.2electrons(neutral atom)
d.20 protons
e.86electrons,125neutrons,82protons(charged atom)
f.0 neutrons

Answer 1

a. Look on the periodic table. 26 protons and 26 electrons tells you the element is #26.
b. 53 protons; element #53.
c. 2 electrons(neutral) so that means 2 protons, also. Element #2.
d. 20 protons. Element #20.
e. 0 neutrons. There is only 1 element with no neutrons. It has a mass of 1.

Answer 2

53 protons, 74 neutrons =Iodine.
2 electrons [ neutral atom] =Helium.
20 protons =calcium.
86 electrons, 125 neutrons, 82 protons [charged atom =lead
0 neutrons =Hydrogen
26 electrons, 29 neutrons, 26 protons =Iron
