The answer is Strontium.
Strontium is a metal element. atomic number of it is 38.
It represents the element with the atomic number of 38 Strontium
You can tell how many protons an element has from its atomic number. So the atomic number of Strontium is 38..so it has 38 protons.
Strontium is group 2 element and is the second element in period 5 with an atomic number of 38
All atoms of the specified data contain 38 protons, 38 electrons (assuming they are not ions), and 50 neutrons. They are atoms of the element Strontium.
The atomic number of am element is determined by its number of either electrons or protons, hence here, it is 18. Therefore the element must be argon which the isotope has mass number 38, as there are 18 protons and 20 neutrons.
The element is potassium. Atomic mass is 38.
Alkaline earth metals
The atomic number is the count of how many protons an atom has in its nucleus (and therefor also the count of how many electrons the neutral atom possesses). The atomic number us unique for each element and positions the element in the periodic table. The element with atomic number 39 is Yttrium (Y).
The atomic number of strontium (Sr) is 38.The atomic weight of Sr is 87.62 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
The element with 38 electrons is Strontium (Sr). Strontium is an Alkaline Earth Metal in Period 5 of the Periodic Table. Strontium has 38 electrons, 5 electron shells and 2 electrons in the outer shell.
