Which statement correctly describes the phosphate ion, ? it is composed of one phosphorus atom and four oxygen atoms covalently bonded together, and there is a –3 charge distributed over the entire ion. it is composed of one phosphorus atom and four oxygen atoms covalently bonded together, and there is a –3 charge on the phosphorus atom. it is composed of one phosphorus atom and four oxygen atoms ionically bonded together, and there is a –3 charge distributed over the entire ion. it is composed of one phosphorus atom and four oxygen atoms ionically bonded together, and there is a –3 charge on the phosphorus atom.

It is composed of one phosphorus atom and four oxygen atoms covalently bonded together, and there is a –3 charge distributed over the entire ion.

Explanation:

The formula of phosphate ion is PO₄³⁻

The formula shows a phosphorus atom surrounded by 4 oxygen atoms.

For this bond to be established, phosphorus would be covalenty bonded to the oxygen atoms.

A covalent bond arises when two atoms with similar zero or very small electronegativity difference(≤ 0.5 ) combines. The electronegativity difference between phosphorus and oxygen is less than 0.5 and the two atom would bond by sharing of their electrons.

The net charge on the resulting radical is a -3 charge which it uses to form other bond types with other atoms. The charge implies an excess of 3 electrons on the radical formed.

more info ? ? i don't understand what the question is

explanation:

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
