The Periodic Table
Who is the father of the Periodic Table?
Dmitri Mendeleev
What is the 1st column on the periodic table (not including hydrogen) called?
Alkali Metals
What group number is the oxygen family?
Group 16
What are valence electrons
electrons on the outermost shell
What are the 2 types of bonds we have talked about?
Ionic and Covalent bonds
What are the horizontal rows called?
Periods (1-7)
List two characteristics of group 2 metals
conductive of heat & electricity, ductile, malleable, high luster, 2 valence electrons, and form a +2 cation
What is group 18 called?
Noble gases
What is a positively charged ion called?
cation
What type of atoms are involved in a covalent bond?
2 nonmetals
What are the vertical columns called?
Groups, Families (1-18)
What group number is the Boron family?
Group 13
What are groups 3 - 12 called?
Transition Metals
What happens to the electrons of an atom when it becomes an anion?
gains electrons
Why do atoms want to bond with one another?
To fill their outermost shell
Elements are put into rows by increasing _____
Atomic Number
What is group 17 called?
Halogens
What is the name of the family for elements #57-71?
Lanthanide Series
Give an example of 2 elements that would make an ionic bond.
answers vary; metal and nonmetal needed
If an atom has 6 valence electrons, which group is it in and how many bonds does it want to form with other atoms?
Oxygen group: 2 bonds
How are certain elements in a group similar in regards to physical and chemical properties?
They react with other elements in similar ways. They may share similar color, metallic character, etc.
What part of the periodic table is composed of man-made metals?
Actinide Series
What separates the metals from the nonmetals on the periodic table?
What type of elements reside along this structure?
Give an example of one metal and one nonmetal.
The stair-step structure, metalloids, metal/nonmetal answers vary
Why do ionic bonds form?
The atoms lose/gain electrons that result in opposite charges that attract the ions to one another.
Which part of the atom is the responsible for bonding with other atoms (be specific)? Explain how that part of the atom moves for both types of bonds.
valence electrons: covalent=shared between 2+ atoms
ionic=gain/loss of electrons between 2+ atoms
