Written Answer: Covalent bonds hold atoms together in molecules and polyatomic ions where as intermolecular forces hold molecules together in a liquid or solid. Intermolecular forces are generally much weaker than covalent bonds.
Explanation/Evidence: "In contrast to intramolecular forces, such as the <u>covalent bonds that hold atoms together in molecules and polyatomic ions</u>, <u>intermolecular forces hold molecules together in a liquid or solid.</u> <u>Intermolecular forces are generally much weaker than covalent bonds."</u>
False. A group of cells is called a tissue.
J.J. Thomson discovered and identified the electron, which was the first subatomic particle to be discovered. R.A. Millikan determined the unit charge of the electron in 1909 with his oil drop experiment. Thus allowing for the calculation of the mass of the electron and the positively charged atoms. Ernest Rutherford overturned Thomson's model in 1911 with his well-known gold foil experiment in which he demonstrated that the atom has a tiny and heavy nucleus. James Chadwick discovered the Neutron in atoms.
Answer:
6 atoms total; 4 H^+ atoms, 2 O^2- atoms
Explanation:
2(H2O)
2 * 2H atoms = 4 H atoms
2 * 1 O atom = 2 O atoms
4+2 = 6 total
