How do we know if an element is a metal, nonmetal or metalloid?

Look on pg. 196-197

1. Metalloids – are in green boxes- YOU COLOR THEM ORANGE

2. Nonmetals – are in yellow boxes – YOU COLOR THEM BLUE

3. Metals – are in blue boxes – YOU COLOR THEM IN GREEN

Review1)The smallest particle that makes up everything and keeps the characteristic of that substance is a/an _______________.2)The negatively charged particle in the atom is called: ______________3)The positively charged particle in the atom is called: ______________4) The particle that has no charge in the atom is called: _______________5) What is the charge of the nucleus? Why?

Review6)Where are the electrons located in the

atom?7)Where are the protons located in the atom?8)What particles are located in the nucleus?9) What part of the atom has the most

volume?10) What is an isotope?11)What are the three isotopes of Hydrogen?12)What happens if I have more or less

electrons than protons

13)On the P.T. what tells you the number of electrons in a neutral atom?

14)What does the atomic mass tell you about the atom?

15)Find Oxygen. How many protons does Oxygen have?

16) Find Sodium (Na). How many neutrons does Sodium have?

17) What happens to the identity of the atom if it gains or loses a proton?

18)What happens to the atom if I add or subtract a neutron from an atom?

Vocabulary

1) Molecule – when 2 or more atoms are bonded together; it can be 2 of the same atoms (O2) or 2 or more different atoms (CO2)

2) Isotope – same element; same # of protons, different # of neutrons

3) Element – a pure substance made up of the same type of atom; protons determine the identity of the atom; if you change the # of protons, the element changes

4) Ion- a charged atom; more or less electrons than protons; electrons determine the charge

Power Notes – Atomic Structure –Periodic Table Connection

1)Using your Periodic Table – Complete the information for the charts.

2)PAY ATTENTION to Capital and Lower Case Letters
