4The nucleus is made up of two atomic sub particles.
5The nucleus is made up of two atomic sub particles. ++Nucleus++a positively (+)chargedProton
6The nucleus is made up of two atomic sub particles. +++Nucleus+a positively (+) a particle with NOcharged charge (0) called aProton Neutron.
7The electron cloud is made up of one atomic sub particle.
8The electron cloud is made up of one atomic sub particle. a negatively (-) charged Electron--++-++-
9This is a Bohr model of the Beryllium atom. --++-++-
10This atom has a charge that is in equilibrium This atom has a charge that is in equilibrium. 4 positive charges balance out the 4 negatively charged electrons. The neutrons carry NO charge and therefor have no effect on the charge of the atom.--++-++-
11Atoms lose their protons or neutrons but it is extremely difficult and time consuming. They can lose their electrons very easily.--++-++-
12If this Beryllium atom losses an electron it would become positively charged. -+-+++-Because there are more positively chargedprotons than negative charges.
13If this Beryllium atom loses an electron it would become positively charged. It is no longercalled an atom.It is called anion.-+-+++Specificallya cation.-Because there are more positively chargedprotons than negative charges.
14- - - - - + + + + Specifically an anion. If this Beryllium atom gains an electron it would become negatively charged.-It is no longercalled an atom.It is called anion.-+--+++Specifically an anion.-Because there are more negatively chargedprotons than positively charged protons.
15Using the periodic table to create a Bohr Model of an atom. The periods (rows)Indicate the number ofOrbitals (energy shells orelectron shells)that make up theelectroncloud.
16Using the periodic table to create a Bohr Model of an atom. Columns (called groups or families) indicate the number of electronsthat can be found in the outermost energy shellcalled the valenceShell.
17How many energy shells does Potassium (K) have? .
18How many valence electrons (electrons in the outer shell) does Potassium (K) have? .
19Each square of the periodic table gives particular information about the atoms of an element. Txt. P. 19The atomic number tells youHow many protons andElectrons the element has.The Chemical symbol ofThe element.The atomic mass madeup of protons andNeutrons.Subtracting the atomic number from the mass, will give us the number of neutrons in the element
20Electron configuration rules 1 Electron configuration rules 1. The innermost shell, due to its radius, can only hold 2 electrons. 2. The next shell can hold 8 electrons. 3. The third shell can hold up to 18 electrons. 4. The 4th shell can hold up to 32 electrons.
21With these rules in mind create a Bohr model of Al.
22Al is in the 3rd period and 13th group Al is in the 3rd period and 13th group. As a result, we know that AL has __electron shells and___electrons in its valence shell. Its atomic number is_____and so has___protons and___ electrons.Its atomic mass is___ and so it has _____neutrons.
