Iron/Atomic number
In February, we have selected iron, the most abundant element on Earth, with chemical symbol Fe (from the Latin word “ferrum”) and atomic number 26. A neutral iron atom contains 26 protons and 30 neutrons plus 26 electrons in four different shells around the nucleus.
How many neutrons does strontium 87 have?
50 neutrons
Strontium has 38 protons while 84Sr, 86Sr, 87Sr and 88Sr have 46, 48, 49, and 50 neutrons, respectively. Although 87Sr occurs naturally in 7.00 % of strontium atoms, it is also produced by radioactive decay from 87Rb (37 protons and 50 neutrons).

What happens to element 87 on the periodic table?
The result of this is that a neutron in the nucleus turns into a proton. When element 87 in the periodic table (francium) does this, the extra proton means that it becomes element 88 (radium).
Are there 87 protons and 136 neutrons in an atom?
So there are 87 protons and 136 neutrons. The 87 electrons are split up between seven energy levels. But they are not split evenly. There are two electrons on the first, eight on the second, 18 on the third, 32 on the fourth, 18 on the fifth, eight on the sixth, and only one on the seventh.
How many electrons and protons are in francium?
Francium’s symbol is Fr. The atomic number, which is how many electrons and protons there are, is 87 each. The atomic mass is 223. 223 is the sum of protons and neutrons.
How many protons, neutrons and electrons does rhodium have?
Rhodium has 45 protons, 58 neutrons and 45 electrons: 46: Palladium has 46 protons, 60 neutrons and 46 electrons: 47: Silver has 47 protons, 61 neutrons and 47 electrons: 48: Cadmium has 48 protons, 64 neutrons and 48 electrons: 49: Indium has 49 protons, 66 neutrons and 49 electrons: 50: Tin has 50 protons, 69 neutrons and 50 electrons: 51
