1) ____________is anything that occupies space and has mass.

Page 3: Atoms and Reactions Test 1a Biology Benjamin McMullin

2) _______________ are particles in an atom that are positively charged, composed of two Up Quarks and one Down Quark, and have a mass = 1 amu.

3) What does “amu” stand for? _______________.

Page 4: Atoms and Reactions Test 1a Biology Benjamin McMullin

4) Electrons are located in, and rapidly travel through, the ______________ around the nucleus (in energy levels), created by the movement of the electrons.

Page 5: Atoms and Reactions Test 1a Biology Benjamin McMullin

5) The smallest combined unit of atoms with covalent bonds is called a _______________ . 

Page 6: Atoms and Reactions Test 1a Biology Benjamin McMullin

6) The number of _____________ in the nucleus of an atom is what determines what element it belongs to.

Page 7: Atoms and Reactions Test 1a Biology Benjamin McMullin

7) The total number of protons and neutrons in an atom is called its _____________ . 

Page 8: Atoms and Reactions Test 1a Biology Benjamin McMullin

8) ________________ are particles in an atom that is negatively charged, a fundamental particle, and have a mass = 0.000548579909 amu.

Page 9: Atoms and Reactions Test 1a Biology Benjamin McMullin

9) _____________ is when the nucleus of atom throws out particles (either alpha or beta) because the atom decays.  

Page 10: Atoms and Reactions Test 1a Biology Benjamin McMullin

10) ____________ are particles in an atom that has no charge, composed of one Up Quark and two Down Quarks, and have a mass = 1 amu.

Page 11: Atoms and Reactions Test 1a Biology Benjamin McMullin

11) An atom’s Atomic Number is determined by the number of _______________ it has.

Page 12: Atoms and Reactions Test 1a Biology Benjamin McMullin

12) The number of electrons in the outermost electron shell of an atom are called _______________ electrons and determines the chemical properties of that atom.

17) Many molecules (only covalently bonded) have the protons within the molecule scattered unevenly around the molecule’s shape. This unevenness of the positive charges in the molecule causes the electrons to be shared unevenly also, with the electrons spending more of their time around the greater number of protons and less around the other areas of the molecule. 

This unevenness of the sharing of electrons and their negative charge creates molecules with poles – slightly positive and slightly negative, hence are called ________________ molecules.

18) Elements can combine chemically to form ______________.

Page 16: Atoms and Reactions Test 1a Biology Benjamin McMullin

19) Chemical bonds can hold atoms together in two different ways: _____________ bonds and _____________ bonds

Page 17: Atoms and Reactions Test 1a Biology Benjamin McMullin

20) When an atom loses or gains electrons, it becomes electrically charged and becomes an _____________ .  

Page 18: Atoms and Reactions Test 1a Biology Benjamin McMullin

21) _______________ bonding occurs when pairs of electrons are shared by atoms. 

Page 19: Atoms and Reactions Test 1a Biology Benjamin McMullin

22) Atoms have Protons (and Neutrons) in the area of the atom called the _____________.  

Page 20: Atoms and Reactions Test 1a Biology Benjamin McMullin

23) If a hydrogen atom is at the positive end of a polar bond, it is called a ______________ bond.

24) A ______________ is a liquid consisting of two or more substances evenly mixed. 25) The dissolving agent (the larger amount of substance) is called the _______________. 

26) The dissolved substance (the smaller amount of substance) is called the _______________.
