Which statement is not true about electrons? electrons have a negative charge. the orbit of electrons around the nucleus is like a cloud. the path an electron moves on is not very straight. the basic unit of matter is the electron.

The basic unit of matter is the electron.

Explanation:

Electrons have a negative charge.

Above statement is true because electron is a negatively charged particle and its charge is given as e = .

The orbit of electrons around the nucleus is like a cloud.

Above statement is true as electron forms a cloud around the nucleus and that cloud is known as orbit of electron.

The path an electron moves on is not very straight.

Above statement is true as Electron moves around the nucleus in closed loop and in this path centripetal force is given by electrostatic attraction force

The basic unit of matter is the electron.

Above statement is not correct as we know that basic unit of matter is not electron but it consist of electron, neutron and proton
