All in the Family
All members of a family have the same number of these.
What are valence electrons?
This element has 4 valence electrons and is found in all living thins.
What is carbon?
He devised the first periodic table which was based on increasing atomic masses.
Who is Mendeleev?
This group of metals can form multiple charged ions which may form colored solutions because they have multiple oxidation states.
What are transition elements?
This term means the metal can be hammered or rolled into sheets.
What is malleable?
This family contains members with 7 valence electrons.
What are the halogens (Family 17)?
This transition element is a liquid at room temperature.
What is mercury?
He constructed the first periodic table arranging the elements in order of increasing atomic number.
Who was Moseley?
These are the electrons involved in bond formation.
What are valence electrons?
This term means the ability to stretch a substance into a wire.
Members of this family have a filled valence electron ring.
What are the Noble Gases?
This element has an electronegativity of 4.0 and is the most reactive nonmetal.
What is fluorine?
This is another name for the horizontal rows of the periodic table.
What are periods?
The atomic mass and electronegativity of the elements tend to do this as you move down a family on the periodic table.
What is the atomic mass increases and electronegativity decrease.
This is the term given to half the distance between the nucleus and outermost electron shell.
What is the atomic radius?
The members of this family have 1 valence electron.
What are the Alkali Metals (Family 1)?
This element is used in lighter than air balloons and is used instead of hydrogen because it is chemically very stable.
What is helium?
This is another name for the vertical columns on the periodic table.
This is what happens to the atomic mass and electronegativity as you move across a period on the periodic table.
What is atomic mass usually increases and the electronegativity increases?
This group 13 element is a metalloid.
What is Boron?
Members of this family include calcium and have 2 valence electrons.
What are the alkali earth metals?
This alkali earth metal is required for strong bones and teeth.
What is calcium?
This grouping of elements are found near the zig zag or step like line of the Periodic Table.
This refers to the energy needed to remove an electron from an atom.
What is ionization energy?
Different forms of an element such as O2 and O3 are called this.
What are allotropes?
