Atomic Radius
What units of measurement do we use for the atomic radius?
Picometers (pm)
What is another word for electronegativity?
Charge
Why do atoms want to complete the duet and octet rules?
To become stable.
What type of bond is C6H12O6?
Covalent Bond
What middle school did Mr. Menjivar go to AND work at?
Roy Romer MS
What happens to the size of the atoms as you go through each period from left to right?
The size decreases, and the atoms get smaller.
What do we call an atom that has either lost of gained valence electrons?
Ion
Why do metals tend to lose valence electrons?
Since they have less than 4 valence electrons it is easier to lose them than it would be to gain enough to complete the duet or octet rules.
(Mr. Menjivar will judge accordingly)
What types of bonds can you have in a covalent bond?
Single, double, and triple.
Describe the concept of the Lewis Structure.
A model of an atom that uses the element symbol and the valence electrons only.
What happens to the size of the atoms as you go down each group from top to bottom?
The size increases, and the atom gets bigger.
What is a cation and what happens to its size?
A positive atom that has lost valence electrons and that decreases in size.
What element is an exception in its group when it comes to the number of valence electrons and why?
Helium (He) in group 18. Since it is in period one and only has one electron shell it can only hold up to 2 valence electrons.
What do we call the electrons in the outermost electron shell?
Valence Electrons
How many elements are in the periodic table? How many groups? How many periods?
118 elements, 18 groups, 7 periods
What causes elements in the same period to decrease in size as you move from left to right?
Coulombic Attraction
What do we call an atom that has gained valence electrons and has increased in size?
Anion
What is the name of the groups we skip in the valence electron rule, what number to what number, and why do we skip them?
Transitional metals. Groups 3 to 12 because they have varied/random number of valence electrons.
What type of elements are involved in a covalent bond and how is a covalent bond created?
Non-Metals, electrons are shared.
When is Mr. Menjivar's birthday?
Explain the process of determining the atomic radius of an atom.
Put 2 atoms of the same element next to each other. Measure the distance between the two nuclei and divide that distance by 2.
(Mr. Menjivar will judge accordingly)
What is the energy required to remove an electron from an atom called?
Ionization Energy.
Using your knowledge of the Bohr Model and valence electrons, determine how many electrons the element Francium (Fr) has.
43 Electrons
What type of elements are involved in an ionic bond and how is an ionic bond created?
A metal and a non-metal.
1. Transfer of electrons
2. Change of charges
3. Opposite charges attract
How many dogs live in Mr. Menjivar's household? and what are their names?
3; Zuko, Buu, and Solovino (Vinni)
