Question

Why can an electric current pass easily through a metal?

1-The positive nuclei metal atoms strongly attract their negative valence electrons
2-Positively charged metal ions move freely from one end of a metal to the other
3-Negatively charged electrons can move freely through a metal
4- positively charged metal ions are arranged in crystals

Answer 1

Answer:Negatively charged electrons can move freely through a metal

Answer 2

Answer: The Correct answer is 3) Negatively charged electrons can move freely through a metal

Step-by-step explanation:

The electric current can pass easily through a metal because the electrons or negatively charged ions are relatively free to move in metals. So, whenever current pass-through metals, electrons carry electricity and pass it through the metal. The movement of these electrons are the reason for conduction of current in metals.
