This preview shows page 3 out of 3 pages.

Nonmetals- with the exception of hydrogen, they appear to the right side of the periodic table. They can be found in three forms (solid, liquid and gas). They are 18 elements. They are not shiny and they do not conduct electricity (except graphite) Metalloids (Semimetals)- they have some properties of metals and some properties of nonmetals. They are 6 elements: Boron, Silicon, Germanium, Arsenic, Antimony, and Tellurium. Ion An atom with an unequal number of protons and electrons (in the normal conditions, an atom is neutral). Ionization energy- the energy required to remove the most loosely held electron from an atom in the gas phase. ionization energy increases from down to up in a column and from left to right across a row. Ionic Compound- matters are electrically neutral (uncharged). The total number of positive charges must equal the total number of negative charges. The subscripts in the formulas for ionic compounds represent the ratio of the ions. Cation- usually metals, lose electrons and become positively charged ions Anion - usually nonmetals, gain electrons and become negatively charged ions

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
