How many neutrons are in the element in group 3 period 13?
The element in group 3, period 13 of the periodic table is aluminum (Al). Aluminum has an atomic number of 13, which means it has 13 protons. The most common isotope of aluminum has a mass number of 27, so it has 27 - 13 = 14 neutrons.
Do Elements in a group have the same number of neutrons?
No, none of two elements in any group have the same number of neutrons. But there are such elements across a period, and they are known as isotones. Some examples are; carbon-12 and nitrogen-13 oxygen-18 and fluorine-19 phosphorus-31 and sulfur-32
