The Structure of the atom
A subatomic Particle that is located in the nucleus, has a positive charge and has a mass of 1 amu.
What is a Proton?
What is an Isotope?
An atom with the same number of protons, but has a different number of neutrons.
Solid at room temperature, except for mercury, which is liquid, good conductors of electricity and heat, metallic looking with a shiny luster (ability of a substance to reflect light), ductile (ability of the substance to be pulled into a thin wire), and malleable (ability of the substance to be hammered into sheets without breaking).
What are metals?
What do the last numbers of the columns on the periodic table help us get the number of?
The number of Valence Electrons that are present.
What is put together in a Covalent Bond?
Nonmetal + Nonmetal
What is a Neutron?
A subatomic particle that has no charge, is located in the nucleus, and has a mass of 1 amu.
An atom with the same number of protons with a different number of electrons.
What is an Ion?
Solid, liquid, gas at room temperature, poor conductors of electricity and heat, not metallic looking, they have a dull luster and don't reflect much light, and are brittle (can break apart) when they are solid.
What are Nonmetals?
True or False:
Mass numbers generally tend to get bigger as you go down columns on the periodic table.
True
What is put together in an Ionic Bond?
A subatomic particle that has a negative charge, is located outside of the nucleus on orbitals and has virtually no mass.
What is an electron?
Which type of Ion has a positive charge and which type of Ion has a negative charge?
Cation
Anion
Cation = Positive Charge (Lose Electrons)
(remember t for +)
Anion = Negative Charge (Gain Electrons)
Found along the zigzag line on the periodic table, exception of aluminum, it is considered a metal even though it lies along the zigzag, have no set characteristics, they share properties of both metal and nonmetals, for example they may have a shiny luster but be poor conductors and brittle
Example: Boron, Silicon, Germanium, Arsenic, Antinomy, Tellurium, and Polonium
What are Metalloids?
How many families are on the periodic table?
18
How many valence electrons do you need to have a stable chemical bond?
8 valence electrons
What is a neutral atom?
An atom with the same number of protons and electrons and has no overall charge.
What are the number of protons, electrons, and neutrons for the Isotopes Carbon-12 if:
Mass Number = 12
Atomic Number = 6
Protons = 6
Neutrons = 6
Electrons = 6
Where are metals found on the periodic table?
How many periods are on the periodic table?
7
What are Valence Electrons?
Electrons found in the outermost energy level (ring/orbital)
How do you calculate Atomic Number?
Number of protons = Atomic Number
What is the number of protons, neutrons, and electrons for the Ion Potassium if:
Symbol = K
Charge = +
Atomic Number = 19
Protons = 19
Neutrons = -
Electrons = 18
Where are Nonmetals found on the periodic table?
To the right of the zigzag line on the periodic table.
True or False:
Atomic numbers generally get bigger as you move down the periodic table.
True
How are molecules formed?
When a chemical bond occurs.
