100

What are the elements that act similar to both metals and gases?

Metalloids

100

What is the charge of a proton?

Positive

100

What are ions with a positive charge called?

Cations

100

What are valence electrons?

Electrons in the outer most energy level
200

What is mass?

The amount of matter in an object

200

What is the majority of the period table (columns 3-12)

Transition metals

200

What has equal mass to protons?

Neutrons

200

What charge would a FlourIDE ion have?

Negative

200

Why are noble gases typically unreactive?

Their highest occupied energy level is full.

300

What is a mixture?

A physical blend of two or more componants

300

What is the title of the last column with the least amount of reactivity?

The Noble gases

300

What is the central core of an atom?

The Nucleus

300

What are monatomic ions?

Ions that consist of a single atom

300

Why do elements within a group act similarly?

They have the same amount of valence electrons.

400

What property depends on the type of matter involved?

Intensive property

400

What is the name of the reactive first column on the periodic table?

Alkali Metals

400

What is an atom?

The smallest particle of an element that retains its identity

400

Do you write the anion or the cation first in a binary ionic compound formula?

Cation first, anion second

400

What is the Octet rule?

The rule states that atoms tend to achieve the electron configuration of a noble gas. (8 Valence electrons)

500

What is a homogenous mixture?

Mixture in which the composition is uniform

500

Who made the framework for the modern periodic table?

Dmitri Mendeleev

500

What defines an element's atomic number?

The number of protons

500

What is special about writing a transition metal in a binary ionic compound?

Transition metals can have varying charges, so you have to write a roman numeral to indicate the charge

500

Do nonmetals tend to gain or lose valence electrons?

They tend to gain valence electrons
