The scientist thought that the atom was the smallest particle in the universe is John Dalton. He established the atomic theory which consists of five; elements are made of extremely small particles called atoms, atoms of different element have different sizes, mass and physic – chemical properties, atoms cannot be divided further, destroyed or created, atoms can combine to form compounds and in chemical reaction, atoms can be combined, separated or rearranged.

What causes attraction and repulsion between atoms?

Jobisdone [24]

Answer:

Repulsive forces exist only when atoms are very close to each other. (3/14) "They [the atoms] will approach until both nuclei will simply shove each other because both of them are positive." The balance between the attraction and repulsion forces determines how close the atoms can get. The relationships between the magnitude and direction of repulsive and attractive forces. A stable state of a bond is when attractive forces balance repulsion forces. “A stable state between two atoms is when they attract each other with a force that equals the force that they repel each other.”

babunello [35]

Answer:

It will feel hot.

Explanation:

The part of the metal that has been sitting in the sun will heat up, and because metal is a good conductor, the part sitting in the sun will heat up the part sitting in the dark.

We say metal is a good conductor because it has high thermal conductivity, which mean heat will flow from the hot section of the bar to the cold section of the bat.
