What subatomic particles are in the nucleus of an atom?
Protons and Neutrons.
What is a polyatomic ion?
An atom made of more than 1 atom.
What is the functional group for a ester?
O-C-O-C
What is the definition of density?
The ratio of an object's mass to its volume
How many elements are in this compound CuSO4
There are 3 types of elements.
What determines the number of shells an atom has?
Based on the row and column it is in on the periodic table. (All atoms in the 4th row have 3 shells).
How many valence electrons would fluorine have and how many does it need to become a noble gas?
Fluorine has 7 valence electrons and needs to bond with another atom that only has one valence to become like a noble gas.
What is the HONC1234 rule?
H-hydrogen has 1 bond
O-oxygen has 2 bonds
N-nitrogen has 3 bonds
C-carbon has 4 bonds
What is equation to find the mass of an object?
Equation: Density multiplied by volume
What is the Law of Conservation of Matter?
Matter can not be created or destroyed.
What would the equation AlO need to follow the Rule of Zero charge?
It would need 2 aluminum and 3 oxygen to follow the Rule of Zero Charge. (Al2O3).
What is the electron configuration for Iron?
1s22s22p63s23p64s23d6
What is the structural formula for CH2O2
H-O=C=O-H
Calculate the density of seawater if the mass is 15g and has a volume of 14.6mL
15g/14.6= 1.03g/mL
What is trend between alkali metals and their reactions as you move down the periodic table?
The farther down on the periodic table, the more reactive the alkali metal is.
What does the atomic mass tell you?
It tells you the number of protons, what element it is, where is is on the periodic table, the mass of the element
What is happening to the electrons during the flame lab that created the different flame colors?
The electrons got "excited" which caused them to jump to different shells which is why the flame color changed.
What is the molecular formula for:
O=C=O
CO2
