element locations
Elements!
Periodic table
100
This is the location of the alkali metals.
Where is the first column on the left side of the periodic table called Group 1?
100
The abbreviation of one or two letters used to identify an element is known as this.
What is a chemical symbol?
100
This is what the columns in the periodic table are called.
What are Groups (of families)
200
This is the location of the noble gases.
Where is the last column on the right side of the table? named Group 18?
200
The atomic number is based on the number of these particles in the nucleus of an atom.
What are protons?
200
This is what the rows (going horizontally) in the periodic table are called.
What are Periods? (like in PERIODic table)
300
These charged particles sit in the shells/orbitals surrounding the nucleus.
What are electrons?
300
Because electrons are so small, they do not add to this number.
What is atomic mass?
300
This is the same for all the elements in each Group (column on the periodic table). For example: in Group 1, each element in this group will have one of these. In Group 2, each element will have 2 of these)
What is the number of electrons in the outer shell/orbital? (also called number of valence electrons)
400
The first shell/orbital outside the nucleus can hold this many electrons.
What is two?
400
You find the number of these particles by subtracting the atomic number from the atomic mass.
What are neutrons?
400
These are the electrons involved in chemical bonds with other elements.
What are valence electrons?
500
This is how you determine the number of electrons in an atom.
What is look at the atomic number?
500
A six-sided die is thrown 10 times. It lands on an even number seven times. How is the experimental probability different from the theoretical probability?
The experimental probability is higher than the theoretical probability. (Experimental = 70%, Theoretical = 50%,)
500
This is the same for all of the elements in a period (a row) of the periodic.
What is the number of shells/orbitals carrying electrons around the nucleus? For example - every element in the top row (the first period) has one shell/orbital for its electrons. As you move down the the rows of the table, every row adds one more shell/orbital.
