P3- is a(n) , so it valence electrons. Group of answ er choices anion, gained cation, gained cation, lost anion, lost

anion , gained

Explanation:

When an atom accepts an electron negative charge is created on atom and is called as anion.

When atom loses an electron positive charge is created on atom and is called as cation.

Phosphorous (P) has an atomic number of 15 which means it contains 15 electrons and there are 5 valence electrons.

For formation of , the atom of phosphorous (P) must gain three electrons in its valence shell 3p so as to complete its octet

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
