What is the symbol of the first element to have an electron in the 4d sublevel in its ground state?
The symbol of the first element to have an electron in the 4d sublevel in its ground state is Yttrium, symbolized as Y, with the electron configuration [Kr] 4d^1 5s^2.
What is wrong with the statement ''the atoms of element X are isoelectronic with the atoms of element Y?
The statement is incorrect because isoelectronic means having the same number of electrons, but atoms of different elements have different numbers of protons and electrons. Elements X and Y can have the same number of electrons in their ions, but not in their neutral atoms.
If the chemical symbol is Yb what is the element?
The element yttrium has the symbol Y. This element and the element ytterbium (Yb) are both named for a quarry town in Sweden (Ytterby).
What is yttruim?
Yttrium is a chemical element with symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare earth element".
What element has 3 valence electrons in the 4d sublevel?
The element with 3 valence electrons in the 4d sublevel is Yttrium (Y). It is located in group 3 of the periodic table and has an atomic number of 39. In its electron configuration, Yttrium has the outer configuration of [Kr] 4d¹ 5s², contributing three valence electrons from the 4d and 5s orbitals.
Which element has the symbol y?
The element that has the symbol U is Uranium. Uranium has the atomic number 92 and is part of the unofficial Neodymium family. It has 92 electrons in 7 shells and is radioactive. Uranium is used as a nuclear fuel.
What is the symbal for yetrium?
There is no widely recognized symbol for yttrium. Yttrium is a chemical element with the symbol Y and atomic number 39.

What is wrong with the statement ''the atoms of element X are isoelectronic with the atoms of element Y?
The statement is incorrect because isoelectronic means having the same number of electrons, but atoms of different elements have different numbers of protons and electrons. Elements X and Y can have the same number of electrons in their ions, but not in their neutral atoms.
What element has 39 protons and 50 neutrons?
Yttrium has 39 protons and 50 neutrons.It is represented by symbol Y.It belongs to group 3 of transition metals.
Is Yttirum an element?
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.
Is there a science word that starts with a y?
Yttrium is a science word. It is a chemical element with the symbol Y and the atomic number 39.
If the chemical symbol is Yb what is the element?
The element yttrium has the symbol Y. This element and the element ytterbium (Yb) are both named for a quarry town in Sweden (Ytterby).
What is wrong with the statement the atoms of element x are isoelectronic with the atoms of element y?
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.
If an imaginary compound has a formula of X4Y3 then how many electrons are in the outer shell of each element?
If a compound has the formula X4Y3, then that means that 4 atoms of imaginary element X are combined with 3 atoms of imaginary element Y. The overall charge of the compound is neutral, and so the charges of the 4 X's and the charges on the 3 Y's must cancel out. We need to find the charge on each atom in the compound to figure out the number of electrons in the outer shell. Once we figure out the charge, finding the number of electrons is easy.So what must the charge on each atom be for this to work out? X is written first, and so it is going to be a positive ion, which means that Y is a negative ion. If you try some different combinations of +1 or +2 ions with -1 or -2 ions, you'll find it doesn't work out right -- there is always a net charge on the final compound when you combine them in a 4 to 3 ratio. The only way it works out is this:If X has a charge of +3 and Y has a charge of -4.Now if X has a charge of +3, it must have lost 3 electrons, which means that it has 3 electrons more than a stable octet. That means X has 3 valence electrons (3 + 0 = 3).If Y has a charge of -4, it has gained 4 electrons, which means that it has 4 electrons less than a stable octet. That means that Y has 4 valence electrons (8 - 4 = 4).See the Related Questions to the left for more information about counting electrons and the octet rule in chemistry.
How many unpaired electrons the atom Y has?
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.
What is yttruim?
Yttrium is a chemical element with symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare earth element".
