Matter
100

The dense, positively charged center of the atom.

What is the nucleus?

100

An ion is formed when an atom gains or loses one or more of this subatomic particle.

What is an electron?

100

This term means a group of eight.

What is an octet?

100

Most of the elements on the periodic table are classified as this type of element.

What are metals?

100

This type of matter consists of only one type of atom.

What is an element?

200
An atom is electrically neutral because it has an equal number of protons and these negatively-charged particles.

What is an electron?

200

This is the term for a negatively charged ion.

What is an anion?

200

DAILY DOUBLE! You can wager anything from 0 to all your points.

Draw a Bohr Model for an atom of nitrogen.


Draw a Lewis Dot Diagram for an atom of nitrogen.

200

These unreactive elements are used to make neon signs.

What are the noble gases?

200

The particle formed when two or more atoms bond together.

What is a molecule?

300

An electron enters this state when it absorbs energy and moves further from the nucleus.

What is the excited state?

300

An ion with 8 protons and 10 electrons will have this charge.

What is -2?

300

Metals on the periodic table tend to lose electrons, forming this type of ion.

What is a cation?

300

Elements of the same group in the periodic table occupy the same column and share similar chemical properties because they have the same number of these.

What are valence electrons?

300

This term describes matter that has uniform characteristics throughout.

What is homogeneous?

400

The outermost electron shell of an atom.

What is the valence shell?

400

An ion with 11 protons and a charge of +1 has these many electrons.

What is 10 electrons?

400

Sulfur (element symbol: S) will gain these many electrons in order to achieve a stable electron configuration.

What is two?
400

These highly reactive nonmetals all have 7 valence electrons.

What are the halogens?

400

These types of compounds have high melting points and can conduct electricity when dissolved in water.

What is an ionic compound?

500

Different isotopes of the same element differ in mass because of this subatomic particle.

What is the neutron?

500

An element with a very low electronegativity is likely to form this type of ion.

What is a cation?

500

In the covalent compound water, the oxygen atom has a complete octet of valence electrons, but each hydrogen does not. How many valence electrons does each hydrogen atom have?

What is two?

500

As you move from left to right along a period (row) of the periodic table, this characteristic describing the amount of energy required to remove an electron increases.

What is ionization energy?

500

Paint is an example of this type of mixture, since it is made up of solid pigment particles mixed throughout a binder.

What is a suspension?
