Chemical Bonding
Write the chemical formula for CO
Carbon Monooxide
Define Intermolecular Forces
An intermolecular force is the force that mediates interaction between molecules, including the electromagnetic forces of attraction or repulsion which act between atoms and other types of neighbouring particles.
Describe what happens to bonds in chemical reactions
Atoms must be shared or lost to fulfill the octet rule.
Why is lab safety important?
So no one gets hurt and everything thing is done with no negitive consequences
How is the periodic table organized?
by their increasing atomic number (number of protons in the nucleus), arranging them in horizontal rows called periods and vertical columns called groups
Why do atoms bond? (What rule?)
Octete Rule, needing to get a complete valence shell of 8
Define Dipole-Dipole interactions
the attraction between hydrogen and lone electron pairs of a strongly electronegative molecule
Identify single and double replacements
In a single-replacement reaction, one element replaces another in a compound, while in a double-replacement reaction, two ionic compounds exchange ions, resulting in two new ionic compounds
List two saftey rules that must be followed in the classroom
Wear appropriate attire and eye protection, follow specific instructions, and be aware of emergency equipment locations.
Is oxygen a metal, nonmetal, or semimetal?
nonmetal
How is an ionic bond formed?
Transfers metal to non-metal
Define Hydrogen Bonding
the attraction between hydrogen and lone electron pairs of a strongly electronegative molecule
Describe synthesis
the process of creating a new, complex chemical compound from simpler substances
What is a direct relationship
a scenario where two variables move in the same direction; if one increases, the other increases, and if one decreases, the other decreases
How many core and valence electrons does Be have?
2 valence 2 Core
What are the execptions to the octect rule?
Hydrogen and Helium
What is the difference between cohesion and adhesion?
Cohesion sticks to the same molecule, and adhesion sticks to different molecules
Describe combustion
a chemical reaction between a fuel and an oxidant, usually oxygen, that produces energy in the form of heat and light, most commonly as a flame
What is an indirect relationship?
describes a situation where one variable influences another through an intervening variable, rather than directly.
How many core and valence electrons does Li have?
1 valence 2 core
Explain the difference between single, double, and triple covalent bonds.
Single bonds involve one pair of electrons, double bonds involve two pairs, and triple bonds involve three.
Explain how the strength of intermolecular forces affects physical properties such as boiling point, state at room temperature, and evaporation.
Combustion
What is the law of Conservation of Matter?
atoms, matter, cannot be created or destroyed
Identify possible sources of error when experimenting with chemicals.
spills, incorrect amounts, incorrect labels, etc.
How many core and valence electrons does Au have?
79 core, 1 valence
