100
Very reactive group 1 metals with only one valence electron in their outer shell
What are alkali metals?
100
A chemical bond that occurs when one atom "steals" electrons from another atom, causing the charged atoms to then stick together
What is an ionic bond?
100
When drawing Lewis structures, most atoms need ____ electrons to be stable (unless they are hydrogen, boron, or another exception!)
What is 8 electrons?
100
What is the name of CO?
What is carbon monoxide?
100
H2 + O2 → H2O
What is 2H2 + O2 → 2H2O?
200
Nonreactive elements that have a stable octet of eight electrons in their valence shell
What are noble gases?
200
Which type of bonding shares electrons?
What is covalent bond?
200
Draw the Lewis Dot Structure for PCl3
200
Apart from water, what is the chemical name for H20?
What is dihydrogen oxide?
200
Balance N2 + H2 → NH3
What is N2 + 3H2 → 2NH3?
300
The side on the periodic table that contains most of the nonmetals
What is right side?
300
Which compound usually has a higher boiling point - ionic or covalent? Explain why.
What is ionic compounds - because they have a crystal lattice made of oppositely-charged ions that stick together strongly; in contrast, covalent molecules are held together by weak intermolecular forces
300
The formula for a compound formed from Oxygen and Aluminum
What is Al2O3?
300
Write the chemical formula for lead (IV) oxide.
What is a PbO2?
300
Balance Mg + O2 → MgO?
What is 2Mg + O2 → 2MgO?
400
How does reactivity change as you go down group 1?
What is reactivity increases?
400
Why do most atoms want to bond?
What is atoms want to decrease their potential energy and become stable?
400
The charge on tin in SnCl4 (write in roman numerals)
What is Tin (IV)?
400
What is the name of CuSO4?
What is Copper (II) sulfate?
400
Balance Al + Cl2 → AlCl3 and identify the type of reaction.
What is 2Al + 3Cl2 → 2AlCl3? Synthesis.
500
How does atomic radius change as you go down a group. Explain why.
What is the atomic radius increases because more energy levels are added, and the electrons get farther away from the nucleus - causing the atom to get bigger?
500
What type of bond does nitrogen gas have?
What is triple covalent bond?
500
Draw the Lewis structure for C2H6.
500
Write the chemical formula for iron(II) sulfate.
What is FeSO4?
500
Predict the products and balance:
____ HCN + ____ CuSO4 → _______ + ________. Identify the type of reaction.
What is 2 HCN + CuSO4 → H2SO4 + Cu(CN)2
Double Displacement.
