g Suppose that a power supply is connected across two resistors R1 and R2 that are connected in series. The power supply voltage E, the voltage across the second resistor V2, and the first resistance R1 are all known, but R2 is not known. Find an expression for R2 in terms of E,R1,andV2

11 electrons.

Explanation:

Atoms in their neural state, that is, uncharged or non ionized state, always have the same number of protons and electrons.

When they ionized, they will either gain or lose electron or electrons which will eventually make them either positively charged or negatively charged.

Given that an electrically neutral atom has 11 protons. It will definitely has 11 electrons orbiting around it’s nucleus
