Who is the author or creator of the Periodic Table of the Elements
100
two
What is the number of low tides per day
100
The number that determines how many electrons you place on a Bohr model
What is the atomic number
100
carbon dioxide=water>glucose+oxygen
What is the chemical equation for photosynthesis?
200
Metals, Non-metals, Metalloids
What is the three categories into which the periodic table is divided.
200
The gravitational pull of the moon
What is the cause of tides
200
This tells you the number of energy levels an elements model will have.
What is the period number
200
Arteries carry blood in this direction
What is away from the heart
200
The green pigment found in chloroplasts.
What is chlorophyll?
300
Alkali Metals
What is the family on the periodic table that consists of soft silvery metals that have 1 electron in the outer shell. This elements are very reactive especially with water.
300
There are four within a twenty four hour period.
What are tides
300
Carbon has two of these because it is found in period 2.
What is number of energy levels or shells Carbon has?
300
tubes that carry blood to the heart
What are veins
300
They are the first step in the food chain.
What are plants
400
Noble Gases
What is the family found on the periodic table of the elements whose members outer shell consists of 8 electrons and are not reactive
400
Is when tides are especially high or low. This is the cause.
What is when the moon and suns gravitational pull are on the same side of the earth.
400
Each can only have two because then it is full.
What is the maximum number of electrons the first shell of any element can hold.
400
These are where oxygen and nutrients are passed to the cells of the body.
What is capillaries
400
It is necessary for all living things. A by-product of photosynthesis.
What is oxygen
500
Hydrogen and Helium
What are the first two elements found on the periodic table?
500
It is closer to the Earth so its gravitational pull is stronger than the suns.
What is the moon
500
two, eight, and eight
What is the number of electrons found in the first three shells of any element.
500
The nose, windpipe, bronchial tubes, and lungs make up this system necessary for humans to live.
