Overall trends
This is the trend that is the distance between the atom's nucleus and its valence electrons. Across the groups it decreases, and down the periods it increases.
Atomic Radius
This are the main characteristics of most elements found in group 1. Give 2 characteristics
Soft, white, metals, highly reactive, 1 valence electron
element in the same period as xenon that has a lesser electronegativity
A. Argon
B. Zirconium
C. Neon
D. Helium
B. Zirconium
These are the two parts that go into the nucleus of an atom.
Proton and nuetron
This orbits around the nucleus of an atom
electron
This property is how easily the atom attracts electrons. It increases across the groups and decreases down the periods.
Electronegativity
This are the main characteristics of most elements found in group 2. Give 2 characteristics
Soft, white, metals, very reactive, 2 valence electrons
element in the same group as boron that also has a larger atomic mass
A. Gallium
B. Aluminum
C. indium
D. Thallium
E. All of the above
All of the above
This is the element name for the symbol O.
Oxygen
This is the element name for the symbol Ne
Neon
This is the minimum amount of energy that is required to remove an electron from a neutral atom in a gas state. It increases across the groups, and decreases down the periods
Ionization
The element in the same period as astatine that has a smaller atomic mass is...
A. Chlorine
B. Fluorine
C. Tungsten
D. Bromine
C. Tungsten
This are the main characteristics of most elements found in group 17. Give 2 characteristics
Halogen, very reactive, 7 valence electrons
This is the element name for the symbol U
Uranium
This is the element name for the symbol Ca
Calcium
This is the change of energy when an electron is added. This increases across the groups and decreases down the periods.
Electron Affinity
Element in the same period as nitrogen that also has a larger atomic mass.
A. Beryllium
B. carbon.
C. Oxygen
D.Sodium
C. Oxygen
This is the type of elements that are the most common on the periodic table
A. Metals
B. Non-metals
C. Metalloids
A. Metals
The element name for the symbol B is
Boron
The element name for the symbol K is
Potassium
This characteristic is the ability to lose an electron in a chemical reaction. This increases from the bottom left to the top right of the Periodic table
Metallic
Bonus Points!!! This is how you spell my last name
Lumbrezer :)
What element in the same period as cadmium has the greater electronegativity?
A. Iodine
B. Niobium
C. Rubidium
Iodine
This is the element name for the symbol Sb
Antimony
Antimony's symbol is Sb, which comes from “stibium”. Stibium originates from the Greek word “stibi”, meaning mark. This relates to how antimony was used to make black eye makeup.
This is the element name for the symbol Sn
Tin
