What is in the outermost energy level of an atom?
Valence Electron(s)
100
What are the three types of chemical bonding?
Ionic, Covalent, and metallic.
100
What is gravity?
The force of attraction between all objects in the universe.
100
What is a magnet?
An object that creates a strong magnetic field (an area of magnetic force)
200
What does Coulomb's law tell us?
Opposites attract!
200
What does the "rule of eight" apply to?
Electron sublevels
200
Ionic bonding occurs when what happens?
When one atom gives electrons and another takes them.
200
Gravity's unit of measurement is what?
Weight/Newtons
200
What is magnetism?
A force of attraction or repulsion between magnetic
materials.
300
Attraction is what when charges are higher?
Greater
300
What is electronegativity and which way does it increase on the periodic table?
A chemical property that describes a measure of how strongly the nucleus of an atom attracts
electrons when bonding with other atoms; Left to right and bottom to top.
300
Covalent bonding occurs when what happens?
Two atoms share electrons.
300
What effects gravity the most?
Mass
300
A magnetic field is what?
The area of magnetic force around an object.
400
Two electrons repel each other when put in close proximity, what do two protons do?
Repel
400
What is ionization energy and how does it go on the periodic table?
The amount of energy needed to remove the outermost electrons from an atom; Increases from left to right and bottom to top; Decreases from right to left and top to bottom.
400
Metallic Bonding occurs when what happens?
When the atoms in a metal contribute their electrons to a “sea” of shared electrons.
400
Who discovered gravity? (Full Name)
Sir Isaac Newton
400
Where did the ancient Greeks discover the mysterious rock that attracted things like iron?
The city of Magnesia
500
Are anions attracted to cations?
Yes
500
What is an atomic radius and how does it increase?
A measure of atomic size; From left to right.
500
What is ductility?
The ability of a metal to be stretched into a thin wire or
thread without breaking
500
How did Newton discover gravity?
He was taking a nap in the orchard then an apple fell on his head and woke him up and he was curious why it happened so he did research and figured it out.
