ATOMIC STRUCTURE
According to the notes, what are the three subatomic particles that make up an atom?
What are protons, neutrons, and electrons?
This scientist said all matter consists of atoms.
Who is Dalton?
Matter is anything that has mass and?
What is takes up space?
Vertical columns on the periodic table are called these.
What are groups or families?
These elements are shiny, malleable, and good conductors of heat and electricity.
What are metals?
This part of the atom is a dense center containing protons and neutrons.
What is the nucleus?
This scientist discovered negatively charged particles called electrons.
Who is Thomson?
Elements are pure substances made of only one type of this.
What is an atom?
Horizontal rows on the periodic table are called these
What are periods?
These elements are dull, brittle, and poor conductors.
What are nonmetals?
Using the APE rule, atomic number equals the number of these two particles.
What are protons and electrons?
This scientist concluded that atoms are mostly empty space.
Who is Rutherford?
When atoms of different elements chemically bond together, they form this
What is a compound?
Elements in the same group have similar ______.
What are properties?
These elements have characteristics of both metals and nonmetals.
What are metalloids?
Using the MAN rule, neutrons are found by subtracting this from the mass number.
What is the atomic number?
This scientist proposed that electrons move in specific orbits around the nucleus.
Who is Bohr?
H₂ and O₂ are examples of these because they are made from only one element.
What are molecules of an element?
The number of electrons in the outermost shell is called this.
What are valence electrons?
A covalent bond forms when two nonmetals do this with electrons.
What is share electrons?
Atoms with the same number of protons but different numbers of neutrons are called these.
What are isotopes?
The modern atomic model says electrons move within this region around the nucleus.
What is the electron cloud?
What is an Ionic Bond and a compound
Fluorine is located in Group 17 and has this many valence electrons.
What is 7?
An ionic bond forms when electrons are transferred between these two types of elements.
What are a metal and a nonmetal?
