By 'y' I hope your talking about Yttrium and not a variable. The atomic number is 39, so the number of protons is 39. Always remember that the atomic number is the same as the number of protons.

The number of protons in the nucleus of an atom is equal to its atomic number. Can you please provide the atomic number or symbol of atom Y so I can give you the specific answer?
Atom X and Atom Y are isotopes of the same element, as they have the same number of protons but a different number of neutrons. This difference in neutrons results in different atomic masses for each atom while they both belong to the same element.
An atom with 39 protons is the element Yttrium (Y) on the periodic table. It has the atomic number 39, which represents the number of protons in its nucleus. Yttrium is a transition metal with various industrial applications due to its unique properties.
An atom with 17 protons and 20 neutrons would be chlorine-37, which has a total atomic mass of 37 (17 protons + 20 neutrons).
Yes, Yttrium is an element as it has only one type of atom in it: Yttrium atoms. Yttrium (Y) has 39 electrons in total in one atom and, if it is a neutral atom, 39 protons. Yttrium is one of three elements named after an important scientific area of dicovery: Ytter.
For every 15 X atoms in the compound X3Y, there would be 3 Y atoms. This is because the ratio of X to Y in the formula is 3:1, so for every 3 X atoms, there is 1 Y atom.
