What happens if a positively charged rod is brought near a neutrally charged balloon?

A. Nothing will happen until the two objects touch.
B. Electrons in the balloon move closer to the rod.
C. Electrons in the rod move closer to the balloon.
D. Protons in the balloon move closer to the rod.

Explanation:

Electrons are negatively charged particles that surround the nucleus of an atom (when they are not flowing).

Protons are positvely charged particles in the nucleus of the atoms.

Since electrons are the most external particles they are more easily removed and can flow. Protons do not.

A positively charged rod has defficieny of electrons: less electrons than protons.

When a positively charged rod is brought near the surface of a neutrally charged ballon, the positive charge will attract the electrons on the surface of the ballon and will cause them to move closer to the rod. This phenomenun is named charge induction.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
