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.
What element has a atomic mass of 39.9?
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).
How many structures are possible for a octahedral molecule with a formula of AX4Y2?
Two are possible. One has the two Y's next to each other, and the other has them on opposite sides of the central atom.

How many elements are there in CH4?
No, its formula shows that is a compound of hydrogen (H) and carbon (C).
How many electrons are in the element with the symbol Y?
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.
Atom X has 9 protons 10 neutrons and 9 electrons Atom Y has 9 protons 9 neutrons and 9 electrons what best describes how Atom X and Atom Y are related?
The relationship is that Y is the negative ion and X is the neutral atome of the same element. Particle X and particle Y are both atoms, and are of the same element as the number of protons (atomic number) is 9. With the same number of neutrons they are both the same isotope. Particle X is electrically neutral so is a neutral atom, particle Y has a single negative charge and is an anion. Inspecting the periodic table for aelement atomic number 9 the element is fluorine, the isotope is fluorine-19 (the only naturally occuring isotope of fluorine), X is a fluorine atom, Y is a fluoride ion.
If an atom Y contains 6 electrons in the outer shell what will be its valency?
It needs two more electrons to complete octet and hence its valency will be two if it is non metallic.
The particle of an atom with a positive charge?
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)
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.

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.
What is the effective nuclear charge on Y?
Y=39 with 36 inner electrons shielding the 3 valence electrons producing a Zeff of +3
How many protons electrons and neutrons are in an atom of Y?
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)
What is the charge of an ion having Y protons and Y electrons?
It has zero charge.
What is the Lewis structure for HCO2?
"The formate ion (HCO2-) has a carbon atom as the central atom, with a H atom single bonded to the left, an O atom single bonded to the right with two pair of electrons around it, and one double bonded O atom to the top also with two pair of electrons around it. The O atom to the right has an H atom (*) single bonded to it as well."That would make it H2CO2 which is formic acid, with one protolysable H+ (marked * above) leaving the formate anion HCO2-.HCO2-has the Molecular Geometry Trigonal Planar (meaning it is written in a flat (=planar) Y-shape and has 120 degree bond angles).It has the Carbon as the central atom, Oxygen to the right and to the bottom with the Hydrogen to the left. The ion has 18 electrons (remember the ion is negatively charged), which means we will have two single bonds, five lone electron pairs, and one double bond.One Oxygen atom will have a single bond with three lone electron pairs and containing the negative charge of the ion (this takes 1*2 bonding electrons plus 3x2 lone pair electrons). The other doubel bonded Oxygen will have the double bond (taking 2x2 electrons) with two lone electron pairs (2x2 lone pair electrons).The central C atom will have also one singel bonded H atom (1x2 singele bonding electrons).Switching which Oxygen atom contains the double bond will give you its resonance structures.
Is NH3 Ammonia a strong acid?
bcz it has lone pair of electrons on nitrogen atom tht is y it can donate an electron pair so it is lewis base
