what happens to an atom during heating?

Question

in magnesium or iron or aluminium or copper

Answer 1

the atoms start moving faster so theyre energy encreases and the links between them brake up

Answer 2

The electrons surrounding the nucleus move in discrete jumps farther away from the centre as the atom absorbs energy. These are called quantum leaps, the tiniest movement imaginable although the phrase is used by many people to imply a massive jump. It is those tiny movements that cause some materials to expand when heated. I think that's the case but I might have misunderstood the physics.

Answer 3

well they are all solids so the atoms in these elements are packed together closely and are slightly vibarating so when you heat them, they vibarate more and bounce off each other creating more space between them which makes them into a liquid and then with further heating the atoms vibarate even more and eventually turn into a gas..

for the elements you have said - magnesium, iron and copper- they would all take alot of energy to seperate them as they are metals and have strong structures....

i think..lol this is what i remember from chemistry..hope its right as ive just sat a prelim!
lol hope this helps...

Answer 4

If an atom were heated, the electrons will gain energy and move on to a higher energy level.
e.g. Mg --> Mg2+ + 2e-
e.g. Fe --> Fe3+ + 3e-
e.g. Al --> Al3+ + 3e-
e.g. Cu --> Cu2+ + 2e-

If the solid metal mentioned above were heated, they would melt as the atoms gain kinetic energy and move further apart.

Answer 5

The atoms vibrate more vigorously. The electrons do not move faster; they cannot.

Answer 6

It gets excited!
