Electrons
What are valence electrons?
An atom's outermost electrons
In the quantum mechanical model of the atom, are electrons analyzed as particles or waves?
waves
A compound formed by cations and anions held together by their mutual attraction
ionic compound
If an element in a lewis structure has four dots around it, where would it be found on the periodic table?
Group 4A
Why are some chemical formulas written with a Roman numeral after the first element?
Because the element can have more than one charge.
What is wrong with the following electron configuration? 1s(2)2s(2)2p(4)3s(2)3p(6)
2p(4) The three p orbitals can hold a total of six electrons, and they have to be full before you go on to fill other types of orbitals.
How many electrons can each orbital hold?
two
Nitrogen and Flourine react to form a compound. Is it an ionic compound?
No, they are both nonmetals.
How many dots would the lewis structure for Helium have?
8
What is the chemical formula of calcium chloride?
CaCl(2)
How can you know if two elements will have similar chemical behaviors?
The periodic table is constructed so that elements with similar chemistry are in the same column.
What shape is the p orbital?
Dumbbell
Name three properties of metals
They have luster, are malleable, and conduct electricity and heat well.
What is the ideal electron configuration?
What is the chemical formula and the name of the compound formed by magnesium and phosphorus?
Mg(3)P(2), Magnesium phosphate
What do we call the elements in Group 8A of the periodic table? Why are they called this?
Noble gases. They don't interact much with other elements because they have an ideal electron configuration.
When waves overlap so that their crests cancel out, what is that called?
Destructive interference
A chemist trying to react carbon with two other elements, oxygen and magnesium. Which would be more likely to produce an electrolyte?
magnesium
What would the Lewis structure for sodium look like in an ionic compound?
no dots with a positive superscript
What is the chemical formula of Manganese I Oxide?
Mn(2)O
What is the full and abbreviated ground-state electron configuration for zinc?
1s(2)2s(2)2p(6)3s(2)3p(6)4s(2)3d(10)
[Ar]4s(2)3d(10)
How many individual orbitals are found on the third energy level of an atom and what are they?
Nine: one S, three P, five D
Will C(6)H(12)O(6) conduct electricity when dissolved in water?
No, they are all nonmetals
What would the Lewis structure look like for Sulfur in an ionic compound?
eight dots with a 2- superscript
A chemist examines an ionic compound that contains aluminum and one other element. He doesn't know what that element is, but he knows there are three atoms of that element for every aluminum atom. To which group does the unknown element belong?
It belongs to the 7A group.
