What has 53 protons and 74 neutrons?
The most common, stable form of iodine has an atomic number of 53 (protons) and an atomic weight of 127 (53 protons plus 74 neutrons). Because its nucleus has the « correct » number of neutrons, it is stable and is not radioactive.
Why does magnesium have 12 electrons?
The electrons like to be in separate shells/orbitals. Shell number one can only hold 2 electrons, shell two can hold 8, and for the first eighteen elements shell three can hold a maximum of eight electrons. … That means there are 12 electrons in a magnesium atom.
What has 11 protons and neutrons?
Since sodium has 11 protons, the number of neutrons must be 23 – 11 = 12 neutrons.
What has an atomic mass of 12?

What has 7 electrons 7 protons and 10 neutrons?
The answer is very simple, it’s Carbon. Know that, and element is iidentified by its atomic number, which is equal to the number of proton it has. Since the no of proton in this case is 6 the atomic number is also 6 and we know that 6 is the atomic number of Carbon.
What is the charge of an atom with 20 protons and 18 electrons?
For example, a neutral calcium atom, with 20 protons and 20 electrons, readily loses two electrons. This results in a cation with 20 protons, 18 electrons, and a 2+ charge. It has the same number of electrons as atoms of the preceding noble gas, argon, and is symbolized Ca2+.
