The number of protons is equal ti the number of electrons. Yttrium is the element. It is in the d block.
Yttrium has 39 protons and 50 neutrons.It is represented by symbol Y.It belongs to group 3 of transition metals.

The element Yttrium(Y) contains collectively, protons, neutrons and electrons. Its atomic no. is 39. This tells us that it contains 39 protons, 39 electrons and its commomest isotope contains 50 neutrons. giving it an atomic mass of '89' (39+50). At room STP is is a metal and solid. Discovered by Gadolin in Ytterby in Sweden in 1794,.
The element tin has 50 protons.
The element with 50 protons on the periodic table is tin, which has the atomic number 50.
It is the Element Tin
The element is krypton as it has 36 protons and the isotope is 36Kr86.
The atomic number of an element tells us that atom's number of protons. If the atom is neutral, its number of protons is going to equal its number of electrons. Thus, we need only find the element with the atomic number of 39, which is yttrium.
The element tin, with symbol Sn and atomic number 50, typically has 50 protons. Considering protons + neutrons = atomic mass number, if there were 50 protons and 69 neutrons, the total would be 50 + 69 = 119, which is not the atomic mass of tin (approximately 119).
In potassium-39 (K-39), there are 19 protons (since it's the element potassium), 20 neutrons (subtracting the element's atomic number from its atomic mass), and 19 electrons (since atoms are electrically neutral).
protons over 50
The atomic mass of an element is the sum of protons and neutrons in its nucleus. Gallium has an atomic number of 31, which means it has 31 protons. If it has 39 neutrons, then its atomic mass would be 31 (protons) + 39 (neutrons) = 70.
