Periodic table basics
Atomic structure
State of matter
Mixture of all concepts
100
What are groups
The columns on the periodic table
100
What is an electron?
The subatomic particle with a negative charge
100
What is a solid?
The phase of matter where particles are tightly packed and vibrate in place
100
What information about an atom can be found on the periodic table?
The amount of protons (atomic number), element symbol,name, and mass.
200
How to elements become cations (positive ions)
By losing electrons
200
electrons found in specific orbits around the nucleus is
bohr model
200
Whats the difference between physical and chemical properties?
Physical reacts only when appearance is changed and chemical reacts when a new material is produced
200
How does knowing about the periodic table help us understand different kinds of matter?
by organizing elements based on their atomic structure and revealing patterns in their properties (metals, nonmetals)
300
Non-Metals are found on the left or right side of the periodic chart of elements?
right side
300
Discovered the nucleus in 1911 with his famous gold foil experiment
Ernest Rutherford
300
When does this graph reach vaporization?
C to D
300
How does the periodic table help predict how different types of matter will interact in a chemical reaction?
by organizing elements with valence electrons in the same column
400
When Mendeleev made the first periodic table, what did he use to decide the order of the elements?
atomic mass
400
what is the excited state
state of higher energy for an electron
farther from the nucleus
400
Compare sublimation and deposition
Sublimation is when a solid changes directly to a gas and Condensation is when a gas changes directly to a solid
400
Why can some elements mix easily with others to make new types of matter, but others can’t?
based on atomic structure and the drive to achieve a more stable electron configuration
500
What elements are diatomic?
(Hint:H2)
Hydrogen, Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, and Iodine
500
What is the number of neutrons for an isotope of Oxygen with a mass number of 18?
10 neutrons
500
Is this a endothermic or exothermic reaction?
Where is the activation energy located
It is an exothermic reaction and the activation energy is located at B
500
Why do elements in the same row of the periodic table often have different properties?
they add one electron at a time to the same outer electron shell
