how does adding heat impact the speed and arrangement of molecules in an ice cube?
molecules speed up and molecules can move and slide past each other.
molecules slow down, causing their bonds to break. they can now move all about.
causes some molecules to disappear, making the ice cube fall apart.
which particle has a positive charge?
electron
neutron
proton
for each element on the periodic table, the atomic mass tells you
the total number of protons and electrons
the total number of protons and neutrons
the total number of electrons and neutrons
as you go from left to right on a row on the periodic table, the number of protons of each element
decreases
increases
when atoms share electrons, they form.
a covalent bond
an ionic bond
