Where is the first column on the left side of the periodic table called Group 1?
100
An Upper case letter and a lower case letter 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)?
100
This element is in table salt and is symbolized by Na.
(hint: It is an alkali metal)
What is Sodium
100
This is the only element with no neutrons in its nucleus.
What is Hydrogen?
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)
200
This is what P.E.N stands for.
What are protons, electrons, neutrons?
200
This element has an atomic mass of 20 and is a gas.
What is Neon?
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 are Valence Electrons?
300
These are the three subatomic particles in an atom.
What are protons, electrons and neutrons?
300
This element is in period two and has an atomic mass of eleven.
What is Boron
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 that are involved in chemical bonds with other elements.
What are valence electrons?
400
This is the maximum number of electrons that can fit into the second shell/orbital.
What is 8
400
This element is in the fifth period and has properties similar to its cousin gold (Au)
What is silver?
500
This is how you determine the number of electrons in an atom.
What is look at the atomic number?
500
This element is an alkali metal that can be found in our bones.
What is Calcium. (symbol = Ca)
500
This is the same for all of the elements in a period (a row) of the periodic.
What is the number of atomic 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. Every element in the second period has 2 shells/orbitals
500
This is the proper name and atomic mass of the element Mg.
