100
The solid state.
What state are the majority of the elements in?
100
The nucleus.
What is in the center of the atom?
100
The Transition metals.
What is the largest family in the periodic table that consists of mostly metals?
100
"Uncuttable"
What is the Greek meaning of an atom?
200
The number of protons and electrons in an element.
What does the atomic number represent in the periodic table?
200
Isotopes are elements with a different number of neutrons.
What are isotopes?
200
The electrons.
What is the outermost part of an atom, that surrounds it in a cloud like formation?
200
A malleable metal is a metal that can be rolled into sheets or shapes.
What does it mean when a metal is malleable?
200

300
Bromine, the Halogen family Mercury, the transition metals.
What are the only two liquids in the periodic table and, what family are they in?
300
If an atom has one, but not the other, it would be either positively or negatively charged, and atoms cannot have a sort of charge.
Why do atoms have both protons, and electrons.
300

What is corrosion?
300
Oxygen
What element makes up the majority of the human body?
400
18 Families.
How many families are there in the periodic table?
400

Mendeleev arranged the elements in order of increasing atomic mass.
Where did the first organization of the periodic table come from?
500
Lanthanide and Actinides.
What are the two rows on the bottom of the periodic table?
500
A combination of metal and another element, to make a whole new one. For example, combining copper and tin to make bronze.
What are alloys?
500
An atom is the smallest particle of an element.
What is the modern definition of atoms?
500
A group of elements with both metal and nonmetal properties.
What is a semimetal?
500
From atoms.
Where does an element take is identity from?
