Element Name
The zig-zag pattern of elements on the periodic table that separates the metals from non-metals is commonly know as this.
What are metalloids?
The atomic number is based on this.
What is the number of protons?
This is the pattern of how many electrons can be held in each of the orbitals/ energy levels.
What is 2, 8,18?
These are the vertical columns (up and down) on the periodic table.
What is the groups?
One box on the periodic table represents this.
What is an element?
The atomic mass is based on this.
What is the number of protons added to the number of neutrons.
You can find the number of valance electrons something has by looking at this.
What is the group number of the element on the periodic table. (you subtract 10 for groups 13-18 and we also ignore the transition elements)
These are the horizontal rows of the periodic table.
What are periods?
This is the smallest particle of gold you can get.
What is an atom of gold?
These are the charges of protons, neutrons and electrons.
What is positive, neutral, and negative.
This is the number of valance electrons that Bromine has? Bromine is in group 17
What is 7.
Alkali, Alkali Earth Metals, Transition Elements, Halogens, Non-Metals, and Nobel Gasses are some of the names of these.
What are families.
Neon has 10 protons and 10 neutrons. This is the atomic number of Neon.
What is 10?
3CF4 has this many atoms of Carbon and Florine.
What is 3 Carbon and 12 Florine.
The number of electrons in the outer most orbital/ energy level.
What is the definition of valence electron?
If Manganese is left to Iron on the periodic table and Iron has a atomic number of 26, this is the atomic number of Manganese.
What is 25?
Neon has 10 protons and 10 neutrons. This is the atomic mass of Neon.
What is 20?
O3- is it an atom or molecule and how do you know.
What is molecule because there are 3 oxygen atoms bonded together.
This is the number of valance electrons in Hydrogen. Hydrogen is in group 1
What is 1?
Nobel gasses are not found in compounds or bonded with other elements. This is why.
What is the are very unreactive- they don't like to bond with other elements because they have a full number of valance electrons.
