Molecule Unit of matter that results when two or more atoms are joined by covalent bonds Ionic Bond A bond resulting from the electrostatic attraction of a cation for an anion. Brainpower Read More Nonpolar Covalent Bond A bond characterized by an even distribution of charge; electrons in the bonds are shared equally by the two atoms Polar Covalent Bond A bond resulting from unequal sharing of bonding pairs of electrons between atoms Polyatomic Ions Charged g...

HOMEWORK EXAM 1 CHEM 142 QUESTIONS AND ANSWERS GRADED A Is there an attraction between two neutral helium atoms? Explain in detail why or why not. Be sure to include any evidence you have for your claim and how this supports your reasoning. Yes; 2 helium atoms can be attracted because the electrons in the electron cloud are freely moving. This leads to one of the atoms becoming an instantaneous dipole, this will then induce a dipole on the other atom. The opposite partial charges will a...

Valence Outer shell of electrons; the number of unpaired electr...

Which subatomic particle is displaced when two or more atoms combine make a molecule? Correct Answer-Electrons What type of bond is formed when atoms share electrons? Correct Answer-Covalent What determines the number of covalent bonds an atom can create? Correct Answer-the excess or shortage of electrons in its outermost electron shell. Oxygen with 6 electrons in the outer electron shell (that needs 8 to be complete), can make how many covalent bonds? Correct Answer-2 Which of the f...
