100
They are good conductors of heat and electric current.
What is metal?
100
They are group 1A elements.
What are alkali metals?
100
Transition metals belong in this group.
What are group B elements?
100
It is one half of the distance between the nuclei of two atoms of the same element when the atoms are joined.
What is an atomic radius?
100
The ability of an atom of an element to attract electrons when the atom is in a compound.
What is electronegativity?
200
He arranged the elements in his periodic table in order of increasing atomic mass.
Who is Mendeleev?
200
It displays the symbols and names of the elements, along with information about the structure of their atoms.
What is the periodic table?
200
The highest occupied s sublevel and a nearby f sublevel generally contain electrons.
What is an inner transition metal?
200
This increases from top to bottom within a group and decreases from left to right across a period.
What is atomic size?
200
These decrease from top to bottom within a group.
What are electronegativity values?
300
When elements are arranged in order of increasing atomic number, there is a periodic repetition of their physical and chemical properties.
What is periodic law?
300
This group on the periodic table consists of halogens.
What are nonmetals of Group 7A?
300
Elements can be sorted into noble gases, representative elements, transition metals, or inner transition metals based on this.
What is electron configuration?
300
These form when electrons are transferred between atoms.
What are positive and negative ions?
300
An ion with a negative charge.
What is an anion?
400
They generally has properties that are similar to those of metals and nonmetals.
What is metalloid?
400
Noble gases belong in this group.
What are group 8A elements?
400
This element has the symbol Fe on the periodic table.
What is iron?
400
An ion with a positive charge.
What is a cation?
400
These are always smaller than the atoms from which they form.
What are cations?
500
This arranges the elements in order of increasing atomic number.
What is the modern periodic table?
500
Elements in Group 1A to 7A. They display a wide range of physical and chemical properties.
What are representative elements?
500
This element has the symbol Ag on the periodic table.
What is silver?
500
Energy required to remove an electron from an atom.
What is ionization energy?
500
These values tend to increase from left to right across a period.
What are representative elements?
