state whether Y is metal or non metal
Answers
Answer:
If X and Y are two kinds of atoms, there can be possibilities of covalent and ionic compounds.
The ionic compounds mainly formed between an electropositive element and electronegative element. In other words which can lose electron and gain electrons.
Covalent compounds are formed mainly between non-metals which can share electrons with themselves.
X4 will be a covalent compound. Hence it will probably be a non metal. Example of X4 can be taken as of a P4 molecule.
Y2 will also be a covalent compound formed by the sharing of electrons. Like H2 or Cl2 etc. These are mostly non-metals.
XY4 will be a covalent compound. Example for XY4 compound is XeF4.
X+2(Y-1)2 will be an ionic compound in which X will probably be a metal of 2nd group and Y will be a non metal of 17th group.
X+Y- will be an ionic compound in which X is a metal of the 1st group and Y will be a non-metal of 17th group.
Answer:
Y is a metal that is Yttrium..
Explanation:
Because if we go towards left of the periodic table then we will find that most of the elements are metal and they can loose electrons easily
