What determines the amount of orbitals in this Bohr diagram on Cm?
The row the Element is in.
How is the atomic radius found?
The atomic radius decreases from left to right across a period
How do you determine the ionization energy?
The ionization energy increases across a period and decreases down a group.
In each single replacement reaction, which element from the original compound is replaced with the newly introduced compound or element?
: In each single replacement reaction, the second element of the original compound is typically the one to be replaced. The formula typically looks like this: A+BC=AC+B
You start with 3.25g of Na2Me, how many grams o fCm will you need to react?
3.25g Na2Me x 1mol Name/47.12 x 2Cm/1Na2Me x 12.09g Cm/1molCm
How would you find the amount of valence electrons?
You can use the number of protons to determine the amount of valence electrons.
Does the atomic radius increase or decrease when going left to right?
The atomic radius decreases
Would ME or CM have higher ionization energy?
ME
What is the purpose of balancing an equation for a reaction?
Balancing an equation involves changing and multiplying coefficients of elements in a reaction, to ensure there are an equal amount of atoms per each element on both sides of the equation. This also makes it easier to locate and calculate reactants and products.
_Cm+1Na2Me -—>
2CmNa+_Me
2Cm+1Na2Me -—>
2CmNa+1Me
How do you know if the charge is negative or positive?
You determine based on the side that the Element is on.
What direction does electronegativity go?
Electronegativity increases as you move from left to right
How do we recognize that it is not ionic?
Because ionic bonds are formed by a metal and a non-mental. In this case Me counts as a non-metal because it has just one electron. And Cm too because is on the right side of the periodic table
What is the Formula for Water?
H2O
how many elements are on the periodic table?
118
How can you determine the charge of the element?
You can determine the charge of an element by finding how many away the Element is from either 0 protons or 8 protons.
Would CM or ME have higher electronegativity?
CM
How do we know Mew (Me) has 4?
Because of the atoms
What is the formula for Oxygen?
O2
What is the last element on the periodic table?
Oganesson
What is Chemistry?
The study of properties and substances.
What side of the periodic table are Noble Gases located?
The far right side.
What is the first element on the periodic table?
Hydrogen
What is the formula for Carbon Dioxide?
CO2
How many groups are in the periodic table?
9
