Water Molecule |
a molecule made out of two hydrogen atoms and one oxygen; the smallest unit that is still water |
|
|
|
Water Molecule |
Molecule: two atoms that bond together (to fill shells to max) Water Molecule: one oxygen atom and two hydrogen atoms |
H2O |
|
|
Cohesion |
atoms/molecules sticking (attracting) to other atoms/molecules of their own kind |
unite, connect, substance, molecular |
|
|
Hydrogen Bond |
a weak chemical bond that shares electrons between positively charged hydrogen ions and negatively charged ions |
hydrogen, chemical bond, electronegative |
|
|
Positive Charge/Negative Charge |
There are two types of electric charges: positive and negative. Like charges repel and unlike attract. An object is negatively charged if it has an excess of electrons and is positively charged if it has excess protons or uncharged if it has a balance of subatomic particles |
positive, negative, charges, elections/protons |
|
|
Oxygen Atom |
the oxygen atom has 8 protons and electrons, and is a not very reactive gas |
atmosphere, breathe, O, atomic number 8 |
|
|
Hydrogen Atom |
the hydrogen atom has 1 proton and electron, and is a highly reactive gas |
only element that can exist without neutrons |
