An atom is smallest particle of matter that take part in chemical reaction. What happens when two atoms approach one another?

ایک ایٹم مادے کا سب سے چھوٹا ذرہ ہوتا ہے جو کیمیائی رد عمل میں حصہ لیتے ہیں۔ جب دو جوہری ایک دوسرے کے پاس جاتے ہیں تو کیا ہوتا ہے؟
Answer: Attractive and repulsive forces increase.
Explanation

As two atoms come closer, attractive forces (like between electrons and nuclei) try to pull them together.

Simultaneously, repulsive forces (like between electron clouds or nuclei) also increase, balancing the interaction.
