What is the periodic table? A system used to organize elements by properties atomic structure

METALS, NONMETALS AND METALLOIDS @ginasaclausocaro2015

WHAT ARE THE MAIN CATEGORIES OF ELEMENTS?

PROPERTIES OF METAL Most are shiny solids except for Mercury. Ductile- can be shaped into wires. Malleable- can be hammered into sheets. Good conductor of heat and electricity. Melting point: 962 °C Density: 10.5g/mL Ex: Silver (Ag), Gold (Au), Iron (Fe) and Tin (Sn)

PROPERTIES OF NONMETAL Dull, yellow material Brittle-breaks easily Shatters when hammered Poor conductor of heat and electricity. Good insulator (keeps temperature low or high) Melting point: 113 °C Density: 2.1 g/mL Ex: Hydrogen (H), Carbon (C), Nitrogen (N) and Oxygen (O)

PROPERTIES OF METALLOID Shiny, blue-gray material Brittle-breaks easy Shatters when hammered Better conductor of heat and electricity than nonmetal. Melting point: 630 °C Density: 6.7 g/mL Ex: Aluminum (Al), Silicon (Si), Arsenic (As), Boron (B)

What is atomic structure? The amount of protons, neutrons, and electrons that an element has.

Atomic Number= number of protons The periodic table increases in atomic number Atomic Number

The alpha letters used to denote the element Atomic Symbol The alpha letters used to denote the element Atomic Symbol

How much the element weighs *Protons + Neutrons= Atomic Mass Average of all natural isotopes Atomic Mass

elements with different number of neutrons stable and unstable Isotopes elements with different number of neutrons stable and unstable

Label your element on the side of your notes or notes illustrated 1. 2. 3.

Practice reading the Periodic Table With your partner figure out: how many protons, neutrons, and electrons there are for each element.

Horizontal rows are called periods Properties gradually change The periodic Table Horizontal rows are called periods Properties gradually change Atomic number increases Vertical columns are called groups Each group has similar properties **label on your periodic table of elements
