Atoms
What charge does a Proton have?
Positive
What is an Isotope?
Isotopes are two atoms of the same element with same protons and electrons, but different neutrons and mass number
Where are the protons and neutrons located in the model?
Nucleus
What do the dots in the Lewis Dot Structure Represent?
Valence Electrons
What are the two major types of bonding?
Ionic and Covalent
What charge does an Electron have?
Negative
How do you determine the mass number of an element?
Round the atomic weight to the nearest whole number
Where do you place the electrons on this model?
Orbital Shells
How many dots are aloud per side?
2
Ionic bonding does...
Forms ionic compounds. Transfers electrons to form cation or anion
What charge does a Neutron have?
No Charge
What four things are the same in isotopes?
protons, electrons, element, atomic number
In the first four shells, what is the order of number of electrons you can have per shell?
2,8,18,32
What is the max number of valence electrons you can have? (which also makes the atom stable).
8
Covalent Bonding does...
Forms molecules. Shares electrons.
How many P+, E-, and N does Neon have?
10, 10, 10
What two things are different in both isotopes?
Neutrons and Mass Number
What does a bohr model diagram represent?
Atom
How do you determine the number of valence electrons?
Using the groups/column numbers
What is a Cation?
Metals tend to lose one or more electrons to form positive ions called cations “Sodium Ion" +2
Where are electrons located in an atomic structure?
Orbital Shells
What is the mass number of Neon?
20
How many electrons does Sodium have?
11
How many valence electrons does Boron have?
3
What is an Anion?
Non-metals tend to gain one or more electrons to form negative ions called anions. "Fluoride Ion". -1
