mass number = number of protons + number of neutrons. 47 = 20 + neutrons, so neutrons equal 27.
Iodine has 53 protons, while silver has 47 protons.
A particle with 47 protons and a +1 charge is a silver ion, specifically silver-47 or Ag+1.

Several can. Perhaps you meant to ask which has 20 protons, in which case the answer is calcium. (Calcium is also one of the elements that can have 20 neutrons, but it's not the only one.)
isotope of silver
The atomic number of silver is 47. So there are 47 protons
Calcium has 20 Protons. You can determine the amount of Protons in an Element by checking the top number of an element. This is called the Atomic number. Calcium has 20 protons
A silver atom has 47 protons. This is because the atomic number of silver is 47, which represents the number of protons in a silver atom.
Calcium has 20 protons and Chlorine has 17, so 20+17= 37 protons.
An atom's atomic number tells us how many protons it has. If we reference a periodic table, we see that calcium's atomic number is 20. Thus, calcium has 20 protons.
Iodine has 53 protons, while silver has 47 protons.
An atom of calcium-48 has 20 protons and 28 neutrons, while an atom of calcium-47 has 20 protons and 27 neutrons. The difference in neutron numbers is responsible for the difference in atomic mass between the two isotopes, but they both have the same number of protons and are therefore still calcium atoms.
carbon has : 36000 protons 124000 electrons 348850 calcium

20.
it has 47 protons because the atomic number is the same thing as the number of protons
Calcium (element number 20) has 20 protons and 20 electrons.
