Electrons have a charge that is equal in size to, but the __(4)__ of, the charge of a protons. __(5)__ have no charge. __(6)__ and __(7)__ are found in the nucleus, but electrons are found in the space outside the __(8)__. ALL BAGS ON FLOOR PLEASE!!!
Bell Work – 10/31 – pg. 110 All bags on floor please!!! Atoms of different elements have different numbers of __(1)__. The sulfur shown in the figure is assigned atomic number __(2)__ because a sulfur atom has 16 __(3)__. You can use atomic numbers to refer to elements, like names and symbols because each element has a unique __(4)__. Each positive charge in an atom is __(5)__ by a __(6)__ because atoms are __(7)__. Please date bell work!
Bell Work – 11/1 – pg. 109 All bags on floor please!!! Protons, __(1)__, and __(3)__ can be distinguished by mass, __(3)__, and location in an __(4)__. Protons and neutrons have almost the same __(5)__. Electrons have a charge that is equal in size to, but the opposite of, the charge of a __(6)__. Please date bell work!
Bell Work – 11/2 & 11/3 - (Use Back Cover) All bags on floor please!!! Identify the symbol, and amount of protons, neutrons, and electrons for the following atoms: • Neon Mass Number = 20 • Aluminum Mass Number = 27 • Potassium Mass Number = 40 Please date bell work!

Bell Work – 11/9 & 11/10 – Pg. 115 ALL BAGS ON FLOOR PLEASE!!! An __(1)__ can move from one energy level to another when the atom __(2)__ energy. An electron may move up two energy levels if it gains the right amount of __(3)__. An electron in a higher energy level may move down if it __(4)__ the right amount of __(5)__. The size of the jump between __(6)__ determine the amount of __(7)__ gained or lost.
Bell Work – 11/11 – Pg. 116 ALL BAGS ON FLOOR PLEASE!!! Scientists must deal with the __(1)__ when trying to predict the locations and motions of __(2)__ in atoms. An __(3)__ cloud is a visual model of the most likely locations for electrons in an atom. The cloud is __(4)__ at those locations where the probability of finding an electron is __(5)__. Scientists use the electron cloud model to describe the __(6)__ locations of __(7)__ around the nucleus.
Bell Work – 11/14 – Pg. 110 ALL BAGS ON FLOOR PLEASE!!! The __(1)__ number tells you the number of __(2)__ in the atom’s nucleus.
