18 groups. Elements in the same group have similar properties. Periods (Horizontal Rows): 7 periods. Key Trends: chemistry notes ssc
Crystalline form, hardest naturally occurring substance, bad conductor of electricity, three-dimensional network. Hardest natural substance known
Which you are targeting (CGL, CHSL, MTS, etc.)? hardest naturally occurring substance
Energy required to remove an electron. Increases across a period, decreases down a group.
Formed by the mutual sharing of electrons between non-metals. Low melting points. Poor conductors. (e.g., CH4cap C cap H sub 4 H2Ocap H sub 2 cap O
