I2C Quiz 2 Review

Potpourri

100

This state of matter has particles that are locked in place and are vibrating

Solid

200

What is the term for an atom that has either a negative or positive net charge?

Ion

300

Describe the particle movement of a gas.

Particles collide frequently, move freely, and independently

400

How many orbitals does the element Bromine have?

4 Orbitals (period 4)

500

What is the net charge of a sulfur atom with 18 electrons? What is this called? How many protons does this atom have?

charge: -2

name: negative ion

protons: 16

Atoms

100

This subatomic particle is determines what element the atom is

Protons

200

This subatomic particle is negatively charged, lives outside the nucleus, and has no mass

Electrons

300

This subatomic particle lives in the nucleus, has no charge, and helps stabilize that atom

Neutrons

400

What are valence electrons and how do you figure out how many an atom has?

Valence electrons are the electrons that orbit in the outer most orbital/shell. They are determined by the group number in the periodic table.

500

How many electrons does a positive ion of Aluminum with a +2 charge have?

 +2 Aluminum = 13 +protons and 11 -electrons

Phase Change

100

This phase change occurs after ice cream gains thermal energy and turns into a liquid

melting

200

This phase change occurs when the temperature of water in a pot begins to boil, and steam rises

Evaporation

300

This phase change occurs when the temperature cools and clouds begin forming in the sky

Condensation

400

This phase change occurs when the temperature is so cold, frost begins to form on the surface of a car's windshield without any liquid water

Deposition

500

When hot air is blown into a hot-air-balloon, it begins to rise in the atmosphere.

Explain how density, temperature, and air particle movement explains this phenomena.

When the hot air inside the balloon is hotter than the air outside, the particles begin to move faster which increases the volume of the balloon, making it less dense than the air around it. Things that are less dense (balloon) float above things that are more dense (air around balloon).
