Charging by conduction (contact)

Static electricity charging by induction

Explanation:

A body can be charged when another body is made to touch it such that charges are transferred from a charged body to an uncharged body. This is known as charging by contact.

A body can also be charged by induction. In this case, a charged body is only brought near an uncharged body without really touching the uncharged body. Charges are transferred without physical contact of the bodies.

Answer from: Quest

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.

$^{m}_{4}x$ and $^{m}_4y$

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.

$^{m}_{5}x^{-}$

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be $^{9}_{5}be^{-}$ and $^{9}_{4}be$ .

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