What is the smallest representative of a element
An Atom
100
What are the charges of a proton, electron and a neutron?
+, -, and neutral.
100
What is the electron configuration for Krypton atomic # 36
1s22s2s2p63s23p64s24p64d10
100
Why do elements produce certain color when they are heated?
Because each elements has its own footprint.
200
Where are the noble Gases/ stable elements located?
Group 18
200
When you test a element and it doesn't change after testing it. When you test a element and it changes after testing it.
Chemical and Physical property
200
In what energy level does an electron have more energy?
The farther it is from the neucleus, the more energy.
200
Which is the most reactive element of the three sodium, potassium, and Lithium?
Potassium
200
What are the portions of the electromagnetic spectrum
Infrared,X-Rays, Gama-rays, Microwaves, and Radiowaves
300
What is a Chemical group? Give an example.
A family of elements with the same electron configurations Lithium, Sodium, and Potassium.
300
What is ionization energy and how does it work?
The energy required to remove an electron from a gaseous atom at groud state. when an electron has enough energy it pull away from the nucleus and leaves a positively charged ion.
300
Describe the nucleus of the atom.
In the nucleus there are neutrons, and protons and it is surrounded by electrons.
300
What did Rutherford discover when he tested the model of an atom? What was his experiment?
Rutherford shot alpha particels at a thin sheet of gold, when some of the particels bounced back at him he concluded that almost all the mass and posive charge was concentrated in a small part which he called the necleus, he called the positive unit a proton.
300
How is infrared light emitted with electrons?
Electrons jump from one energy level to other energy levels.
400
Why are atomic masses not whole numbers?
There are different isotopes of the elements
400
What is the law of definite proportions?
Elements combine in definite proportions by weight Ex: If you want to make water then you combine 2 Hygrogens and 1 oxygen with the atomic weight of 16 and it forms water without any left overs.
400
How many neutrons are in Radon
mass222-86atomic#= 136
400
Make a Ven Diagram to compare and contrast Fission and Fussion.
Fission: Splitting of atoms Fussion: Joining of atoms Same:Both release energy
400
What portion of the electromagnetic spectrum has the shortest wanelegth?, and the longest?
Shortest: Gamma Rays Longest: Radio waves
500
Based on Calcium's oxidation number how far is it from its nearest noble gas?
Oxidation number +2
500
What is a compound ? Give an example. other than NaCl Is it ionic or covalent Rename it.
A compound is two elements combined together. Ex: KBr it is ionic Potassiumbromide
500
What two forces work in the nucleus to hold the nucleus? Which one is stronger?
What is nuclear force and electrostatic force. Nuclear Force is always strong Electrostaitc force is weak in long distances
500
State the difference between Ionic and Covalent Compounds
Ionic: Force of attraction between the opposite charges of the ionic compound Covalent: nonmetals paring up sharing electrons to be stable.
500
Describe the relationship between wavelength and energy.
The shorter the wavelength the more the energy.
