This man created the first periodic table based on atomic mass
Who is Mendeleev?
These elements are goo conductors of heat and electricity
What are metals?
This organelle is responsible for making proteins
All cells have this organelle, which surrounds the cell and control what comes in and out
What is the cell membrane?
the third color of the rainbow
yellow
This man rearranged the periodic table in 1913 to have the elements listed by atomic number. We use this arrangement today
Who is Moseley?
These elements are usually gases at room temperature; they are located at the right side of the periodic table
What are non-metals?
This organelle contains and protects the DNA for the cell
What is the nucleus?
Located inside the nucleus, this organelle makes rRNA which makes the ribosomes for the cell
What is the nucleoulus?
the man on the 100$ bill
ben franklin
The horizontal rows on the periodic table are called these
What are periods?
These elements make up the stair step; they have properties of metals and non-metals
What are metalloids?
Located in animal cells only, this organelle breaks down dead parts of the cell
What are lysosomes?
These organelles break down food for energy in the cell, the 'powerhouse of the cell'
What is the mitochondria?

knee bones
There are 18 of these vertical columns of elements with similar properties on the periodic table.
What are groups?
Group 1 (first column) are also known as these metals
What are alkali metals?
This has ribosomes on its surface and makes/packages proteins for secretion
What is the Rough Endoplasmic Reticulum?
or
Rough ER
This organelle receives proteins from the ER, and then processes and ships them throughout the cell
What is the Golgi Apparatus?
he was the 2nd president of the united states
John Adams
Elements in the same group same number of these in their outer energy level
What are electrons?
Group 18 (last column) are also known as these
What are the noble gases?
Located only in plant cells, these organelles use photosynthesis to convert sunlight into food
What are chloroplasts?
Appearing during cell division, these organelles pull chromosomes apart
What are centrioles?
sea turtles can eat these without being hurt
jellyfish
