Heat given off by burning coal is Potential Energy and Laser Light is Kinetic Energy.
Answer:
Atoms of elements at the top of a group on the periodic table are smaller than the atoms of elements at the bottom of the group. ... The valence electrons of the larger atoms are farther from the nucleus and are easier to remove, so the metals near the bottom are more reactive than those at the top.
C2H3O2–(aq) + H+(aq) → HC2H3O2(aq)
You need to know the neutrons because the atomic mass is made up of the number of protons and neutrons
