Ions/Ionic Bonding
An ion is called this when there are more electrons than protons.
What is an anion?
The dots around the symbol in a Lewis Dot Structure.
What are valence electrons?
Protons and Neutrons
As you move to the left and down on the periodic table, this increases.
What is atomic radius?
The Lewis Dot Structure of CH4
See PPT Slide 4
A positively charged atom has this structural trait?
What is more protons than electrons?
The number of valence electrons around bromine.
What is 7?
These are found in the nucleus
Protons and Neutrons
Atoms in the same group have the same number of these.
What is valence electrons?
The Lewis Dot Structure of NH3
See PPT Slide 5
What will the charges be for MgS
Mg will be 2+, S will be 2-
The Lewis Dot Structure of Antimony (Sb).
PPT Slide 2
Atoms that have the same number of protons but different numbers of neutrons are called this.
What are isotopes?
Sr, Ca, Ba in order of INCREASING ionization energy.
What is Ba, Sr, Ca?
Lewis Dot Structure for SCl2.
PPT Slide 6
How would you describe the strength of the bond between ions?
It is strong
The Lewis Dot Structure of Selenium (Se).
See PPT Slide 3
How many electrons fill the first energy level?
2 electrons
As electronegativity increases, electrons are pulled inward causing atoms decrease in this.
What is atomic radius?
The Lewis Dot Structure for HCN
See PPT Slide 7
Write the chemical structure for when lithium and nitrogen bond together.
What is NLi3
The Lewis Dot Structure for Chlorine (Cl).
PPT slide 1
If an atom has 22 protons and 20 electrons, what element is it, and is it a cation or anion?
Titanium, cation.
Increasing Ionization energy is due to another increasing trend on the periodic table.
What is electronegativity?
The Lewis Dot Structure of HOCl
