Unit 2 Lecture Study Guide Answers

1. Proton, neutron, and electron. The proton is found in the nucleus. The neutron is found in the nucleus. The electron is found in the outer shell.

2. The atomic number is how many protons and neutrons that the element has. The atomic mass number is determined by adding the protons and neutrons together in the nucleus.

3. An isotope is an atom of the same element but has different mass numbers. An example of an isotope is Hydrogen 1, Hydrogen 2, and Hydrogen 3 but they all have an element number of 1.

4. An ionic bond forms between two atoms with opposite electrical charges; ex: Sodium Chloride. Covalent bonds form when atoms share instead of gaining or losing electrons; ex: H-O-H. Hydrogen bonds are weak bonds between the positive and...
