winter, spring, summer, ATOM
Learn about the Atom--autumn style!
- It is the number above the element symbol
- It is the number of protons, as well, it is equal to the number of element
- Bold, in the middle of box , is the short version of the element name
- It is the number of protons plus the number of neutrons
- The name if an element
- Located at of each square of the periodic table
Bohr Model - See the protons??
- The charge of a neutron is.... IT DOESN'T HAVE ONE!!!!
- The neutron remains neutra
- The neutron is located inside the nucleus, with it's buddy the proton.
- To find the neutron mass....
- Subtract the atomic number (the number of protons) from the ROUNDED atomic mass
- The mass of one neutron is one amu

- The charge of an electron is negative
- Electrons are located in the electron cloud or orbital
- Compared to the protons and neutrons, the electrons are TINY
- The orbitals are located around the nucleus
- In the orbitals are electrons
- In the bohr model, the circles around the nucleus are the orbitals.
The grey subatomic spheres are the electrons
- Electron are located on the orbitals or electron cloud around the nucleus
- The Valence Electron will be located on the outer most orbital
- The valence electrons forms chemical bonds
- The greater the number of valence electrons the less reactive the element is
- When you go across the table, the number of valence electrons increases
- The group numbers 1-2 and 13-18 are the counting numbers across the table for valence electrons
- EX: The element magnesium is located in group 2 so it has 2 valence electrons
- EX: The element boron is located in the 13th group and has 3 valence electrons
- All the elements follow this rule except for the element helium, it is located in group 18 but has 2 valence electrons
The purple subatomic circles located on the outer most orbital are the valence electrons
- The number of protons is the atomic number
- The atomic number is located at the top of the element square
- The number of electrons is equal to the number of protons and the atomic number
- To find the number of neutrons you must:
- Subtract the atomic number from the ROUNDED atomic mass
- The atomic mass number is located at the bottom of the element square
