Name that Element!
100
the center of the atom is called the _______________
nucleus
100
What is the name of the chart where all chemical elements are arranged based on their characteristics and properties?
The Periodic Table of Elements
100
What does the atomic number tell you about an atom?
the number of protons
100
What does the atomic mass of an element tell you?
the total number of protons and neutrons in the atom
100
I have 6 protons, 6 electrons, and 6 neutrons. What atom am I? I'm found in all living things
Carbon
200
what two subatomic particles are located in the nucleus?
protons and neutrons
200
How are the elements on the Periodic Table arranged?
The are arranged based on their properties and characteristics - they are in rows based on their # of protons and the columns represent their electrons and reactivity
200
How do I calculate the number of neutrons in an atom?
Two strategies can be used
1. protons + neutrons = atomic mass
2. atomic mass - atomic number = neutrons
200
Why are most of the atomic numbers on the Periodic Table listed as decimals and not whole numbers?
Most atoms can found with different numbers of neutrons in their nucleus - (ex. Some Lithium atoms have 3 neutrons and some have 4 neutrons. This is why the atomic mass is 6.94)
200
I have 17 protons and 18 neutrons - I am often used as a disinfectant in water. I appear as a yellow gas at room temperature. What element am I?
Chlorine
300
As the larger an atom gets - there are usually more neutrons than protons Why is that?
More neutrons are needed to help keep the atom stable (the larger the atom, the harder it is to keep stable)
300
Identify the charge of the each of the items below
-protons
-electrons
-neutrons
protons = positive
electrons = negative
neutrons = no charge
300
A copper atom has 29 protons an an atomic mass of 64. How many neutrons does it have
35 neutrons
300
A Zirconium atom has 40 protons an an atomic mass of 91. How many neutrons does it have
51 neutrons
300
I have 80 protons and 121 neutrons - I am used in electrical and electronic equipment, such as fluorescent lamps and switches, and in scientific and medical instruments like thermometers and barometers.
I am the only metal that is a liquid at room temperature. What element am I?
Mercury
400
For an atom to be considered balanced (no charge), what does it need?
It needs the same number of protons and electrons (this is because the positive and negative charges each other out)
400

List three specific facts about electrons
1. they orbit the nucleus in shells
2. they have very little mass
3. they move at the speed of light
4. they are negatively charged
500
What is the difference between an element an a molecule?
an element is substance made of all of the same type of atoms; a molecule is when different types of atoms bond together to create a new substance
