An atom of yttrium (Y) has an electron configuration of 1s2,2s2,2p6,3s2,3p6,4s2,3d1, so it has one unpaired electron in the 'd' orbital.
The correct Lewis diagram for atomic nitrogen shows one nitrogen atom with a single unpaired electron in its outer shell, surrounded by three pairs of electrons (a total of 5 valence electrons). This results in a total of five electrons being shown in the diagram.
Nothing's wrong, except that it means elements X and Y are in fact the same element, if their atoms have the same number of electrons. --------- A more clear, correct and short answer: a neutral atom of an element can be isoelectronic only with an ionized atom of another element.
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 geometry for SF6 is octahedral, with a central sulfur atom surrounded by 6 equidistant fluorine atoms situated in the following way: One on the positive x-axis, one on the negative x-axis, one on the positive y-axis, one on the negative y-axis, one on the positive z-axis, and one on the negative z-axis.
There are two different structures possible in an octahedral molecule with a formula of AX3Y3. The two structures are with each substituent atom in one plane of symmetry according to type, or having 2 in one and the other out.
Yttrium (Y) has, for the most part, 39 electrons. In its ion (atom with a charge that has lost or gained electrons) form though, it has 36 electrons.
The Yttrium atom (Y) has 39 electrons. The ion Y3+ will have lost 3 electrons, so the Y3+ ion will have 36 electrons.
The correct Lewis diagram for atomic nitrogen shows one nitrogen atom with a single unpaired electron in its outer shell, surrounded by three pairs of electrons (a total of 5 valence electrons). This results in a total of five electrons being shown in the diagram.
Ionic bonds typically form between atoms with significantly different electronegativities, usually involving a metal (like Atom X) and a nonmetal (like Atom Y). Atom X should have a low electronegativity and a tendency to lose electrons, while Atom Y should have a high electronegativity and a tendency to gain electrons. Additionally, the size difference between the two atoms, where Atom X is larger and Atom Y is smaller, can facilitate the transfer of electrons, resulting in ionic character.
The effective nuclear charge on Y is the positive charge experienced by the outermost electrons in the Y atom, taking into account shielding effects of inner electrons. It can be calculated as the nuclear charge (proton number) minus the shielding effect from inner electron shells.
It needs two more electrons to complete octet and hence its valency will be two if it is non metallic.
Yttrium atom number 39 = 39 protons.There are two isotopes:stable isotope Y89 , with relative atomic mass 89, thus (89-39) = 50 neutronsunstable isotope Y88 , with relative atomic mass 88, thus (88-39) = 49 neutrons(remember p+n=m)
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.
Protons are positive.Then you have the neutrons, which are neutral, and the negative electrons that cancel out the positive charge of the protons.Hope this helps (Y)

== == It is three, the valence electrons basically depends on the last number of the group its in; such as, group 14 the valence electrons would be 4. i hope i helped
The correct Lewis structure for carbononitridic chloride, CClN, includes a central carbon atom bonded to a nitrogen atom and a chlorine atom, with a single bond between each atom. The carbon atom has two lone pairs of electrons.
