Once formed how are coordinates covalent bonds different for other covalent bonds?

Explanation:

Coordinate covalent bonds differs from other types of covalent bonds in that the two atoms bonds in such a way that one member of the bonding pair supplies both electrons to be shared. In normal covalent bonds, both atoms supplies the electrons to be shared.

This type of bond is used to join two covalent compounds together. They can also be used in joining protons to neutral covalent molecules together.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
