Question

The flow of electrical current is possible because electrons are

A) able to move from one atom to another; the atom that loses an electron becomes positively charged and the atom that gains an electron becomes negatively charged.
B) charged particles that move freely between all atoms; when an atom looses an electron it becomes negatively charged.
C) negatively charged and can move between atoms; the atom that looses an electron becomes negatively charged and the atom that gains an electron becomes positively charged.
D) positively charged particles that when transferred between different atoms create ions that are positively charged.

Answer 1

A) Is the answer because electron is negative and so when an atome loses one, he became positive.

Answer 2

The flow of electrical current is possible because electrons are A) able to move from one atom to another; the atom that loses an electron becomes positively charged and the atom that gains an electron becomes negatively charged.

What is electric current ?

The flow of electric charge is called electric current

When an atom lose an electron there occur a positive charge on the atom as electrons are negatively charged particles ,and when lost leave the atom by making it positively charged

hence , option b) and c) are completely wrong

correct answer is A) able to move from one atom to another; the atom that loses an electron becomes positively charged and the atom that gains an electron becomes negatively charged.

since , only free electrons can conduct electricity hence they are able to move from one atom to another, after loosing electron an atom takes up a positive charge since electron is negatively charged particle
