Compounds
What is the name for NaCl?
Sodium Chloride
What is the periodic trend for Atomic Radius?
From left to right, the atomic radii get smaller. Going down a group, the atomic radii increase.
What does Coulomb's Law state?
Coulomb's Law states that the magnitude, or absolute value of the attractive or repulsive electrostatic force between two point charges is directly proportional to the product of the magnitudes of their charges and inversely proportional to the squared distance between them.
How many valence electrons does Carbon have?
4 electrons
By knowing the number of protons in a neutral atom, you can determine:
The identity of the element, the number of neutrons in the atom and the number of common isotopes of the element.
What is the compound of Chlorate?
ClO3
What happens when metals ionize?
They lose an electron and become positive ions.
What is the characteristic of the Bohr model?
The Bohr atomic model have electrons orbiting the nucleus.
How many valence electrons does Chlorine have?
Ions are formed in chemical reactions when:
When atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells.
What is the compound of Sodium carbonate?
Na2CO3
What is the periodic trend for Electronegativity?
Across a period Electronegativity increases, and going down a group Electronegativity decreases.
What does the Pauli Exclusion Principle state?
The Pauli Exclusion Principle states that no two electrons in the same suborbital can have the same spin.

What is ionization energy?
Ionization energy is the amount of energy needed to remove the valence electrons of an atom.
What does Hund's Rule state?
Hund's rule states that unpaired electrons must fill an unoccupied orbital before pairing up with a single electron in a previous orbital.

What is the periodic trend for Electron Affinity?
Going across a period, Electron Affinity is more negative and going down a group, Electron Affinity is more positive.
What does Dalton's Atomic Theory state?
Dalton's Atomic Theory states the each element is made up of indivisible and indestructible atoms, all atoms of a given element carry the same properties, atoms combine in whole number ratios to form compounds and a chemical reaction changes the way atoms are bound together.
