| Group | horizontal row of elements in the periodic table.
🗑
|
||||
| s-block elements | are chemically reactive metals. Contains the alkali metals and alkaline-earth metals. Found in column 1 and 2.
🗑
|
||||
| p-block elements | consist of all elements in group 13 to 18 except helium.Considered with the s block to be the main-group elements.
🗑
|
||||
| d-block metals | first starts when n equals 3. it is the groups from 3 to 12 which is the transition metals.
🗑
|
||||
| f-block metals | on the periodic table it is wedge between group 3 and 4. Involve the filling of the 4f sublevel
🗑
|
||||
| Alkali metals | The elements of group 1 of the periodic table. Have silvery appearance and can be cut by a knife.
🗑
|
||||
| Alkaline Earth metals | The elements of group 2 of the periodic table. Harder denser and stronger than Alkali metals.
🗑
|
||||
| metal | an element that is a good conductor of heat and electricity.
🗑

| main-group or representative elements | an element in the s or p block
🗑
|
||||
| halogens | elements of group 17.Most reactive nonmetals.
🗑
|
||||
| atomic radius | one half the distance between nuclei of identical atoms that are bonded together.
🗑
|
||||
| bonding radius | the distance between two or more elements that are chemically bonded
🗑
|
||||
| ionization energy | the energy required to remove one electron from a neutral atom of an element
🗑
|
||||
| electron affinity | The energy that occurs when an electron is added to a neutral atom of an element.
🗑
|
||||
| valance electron | an electron that is able to be gained,lost, or shared in the formation if a chemical compound.
🗑
|
||||
| cation | a positive ion
🗑
|
||||
| anion | a negative ion
🗑
|
||||
| ion | an atom or group of atoms that have a negative chrage.
🗑
|
||||
| atomic mass unit | a unit of mass that is exzactly 1/12 the mass of a carbon 12 atom, or 1.660540x10-27
🗑
|
||||
| nonmetal | an element that is a poor conductor of electricity and heat.
🗑
|
||||
| isotope | atoms of the same element that have different masses
🗑
|
||||
| shielding effect | electrons in the filled sets of s, p orbitals between the nucleus and outer shell electrons somewhat from the effect of protons in the nucleus
