An element with an atomic number of 15 can make up how many covalent bonds with hydrogen?

I'm stuck =/





Is it 0,1,2,3 or 4?An element with an atomic number of 15 can make up how many covalent bonds with hydrogen?
It is 3. One might think it should be 5, but PH5 is unstable, spitting out H2 to give PH3.An element with an atomic number of 15 can make up how many covalent bonds with hydrogen?
3
an Element with atomic number 15 has electronic configuration 2, 8, 5 (s p d f, forms). It needs 3 electrons on 'd' orbital to get the stable form. It means it needs three electrons which means it can bond with 3 hydrogen





your answer is 3





I hope it helped.. Thank You
