Z=20; 1s22s22p63s23p6 express your answer as an ion

The ion formed is

Explanation:

An ion is formed when an atom looses or gains electron.

We are given:

Atomic number of element Z = 20

The electronic configuration of neutral atom =

The electronic configuration of the ion =

As, the given element is loosing 2 electrons. So, it will form a positive ion having charge of +2.

Hence, the ion formed is

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

your answer would be “dry”
