Unit 6 Flashcards
What pH #’s are acids?
1, 2, 3, 4, 5, 6
What two things combined forms salt?
Metals and nonmetals
What pH # is a neutral?
7
What pH #’s are basics?
8, 9, 10, 11, 12, 13, 14
How do you find the # of protons by only using the element?
It is the same as the Atomic #
How do you find the # of neutrons by only using the element?
Atomic Mass - Atomic #
How do you find the Atomic Mass by only using the element?
Protons + Neutrons
What does the Atomic # equal to?
Protons OR Neutrons
What do all Groups/Families have in common?
They have similar properties (Same amount of Valence Electrons)
What are four physical properties of metals?
Malleable, Luster, Ductile, and Conductors
What are four properties of nonmetals?
Brittle, Dull, Insulators, Many Colors
What is a heterogeneous mixture?
Mixtures that aren’t uniform (the same; different). (Chex Mix (You get different food items every time you reach in the bag))
What is a Colloid?
A mixture that has particles small enough that the particles don’t settle, yet large enough that they can block out light
Ex. Jell-O, Smoke, and Milk
What is a Suspension?
A mixture with large particles that separate by themselves over time
Ex. Snow globe, and muddy water
What is a solution?
A mixture whose particles are so small, they block light or settle to the bottom
Ex. Kool-Aid, Iced Tea, Lemonade
What is a homogeneous mixture?
Mixtures that spread out evenly
Ex. Pouring a glass of Kool-Aid
Where is a metal located on the Periodic Table?
The left side of the zigzagging line
Where is a metalloid on the Periodic Table?
The zigzagging line
Where is a nonmetal on the Periodic Table?
The right side of the zigzagging line
