Electron Configuration and the Periodic Table

QuestionAnswer
Noble gases fall into what numerical group of the Periodic Table Group 18
What governs the atom's chemical properties The electron configuration of an atom's highest occupied energy level
In the modern periodic table how are the elements arranged Vertically in groups that share similar chemical properties and horizontally in rows, or periods
How many periods are there in the modern periodic table Seven
What determines the length of each period in the modern periodic table The number of electrons tha can occupy the sublevels being filled in that period
What number of elements are in Period 1 and what sublevels in order of filling 2 Elements. Sublevels in order 1s
What number of elements are in Period 2 and what sublevels in order of filling 8 Elements. Sublevels in order 2s & 2p
What number of elements are in Period 3 and what sublevels in order of filling 8 Elements. Sublevels in order 3s & 3p
What number of elements are in Period 4 and what sublevels in order of filling 18 Elements. Sublevels in order 4s & 3d & 4p
What number of elements are in Period 5 and what sublevels in order of filling 18 Elements. Sublevels in order 5s & 4d & 5p
What number of elements are in Period 6 and what sublevels in order of filling 32 Elements. Sublevels in order 6s & 4f & 5d & 6p
What number of elements are in Period 7 and what sublevels in order of filling 32Elements. Sublevels in order 7s & 5f & 6d & 7p
How is the period of an element determined From the elements elecron configuration.
How is the periodic table divided Into four blocks s, p, d, and f blocks
What are the block letter for Group 1 & 2 This is the s-block
What are the block letters for Group 3 through 12 This is the d-block
What are the block letters for Group 13 & 18 This is the p-block
What are The block letters for elements labeled 58 - 103 This is the f-block.
In the common periodic table, how are the elements arranged Vertical groups and in horizontal periods
List metals Alkali metals, Alkaline-earth metals, Transition metals
List nonmetals Halogens, Noble gases
The elements of the s block are what type of metals reactive
True or False: Group 1 metals are more reactive than those in Group 2 True
The elements of Group 1 of the periodic table (lithium, sodium, potassium, rubidium, cesium, and francium are alkali metals
Describe alkali metals in their pure state silvery appearance and is soft enough to cut with a knife
Are alkali metals found in nature as free elements No
How is alkali metals stored & why It is stored in kerosene because of the extreme reactivity with air or moisture.
The elements of Group 2 of teh periodic table (berylliu,, magnesiu, calcium, strontium, barium, and radium) are called alkaline-earth metals
Describe Group 2 metals harder, denser, and stronger than teh alkali metals. It has higher melting points.
Can alkaline-earth metals be found in nature as free elements No because they are too reactive
The d-block elements that are metals with typical metallic properties and are often referred to as transition elements.
Transition elements are good conductors of what Electricity
What are the least reactive of all the transition elements Palladium, platinum, and gold
What are examples of transition elements Mercury, tungsten, & vanadium
The p-block elements together with the s-block elements are called main-group elements
For atoms of the p-block elemenets, the total number of electrons in teh highest occupied level is equal to the group number minus what 10
Name the six metalloids boron, silicon, germanium, arsenic, antimony, adn tellurium
The elements of Group 17 (flourine, chlorine, bromine, iodine, and astatine are known as halogens
What are the most reactive nonmetals Halogens
Halogens react vigorously with most metals to form what compounds known as salts
What elements are gases at room temperature Fluorine and chlorine
Which element is a reddish liquid bromine
which element is a dark purple solid iodine
What element is a synthetic prepared in small quantities Astatine
Hydrogen does not share teh same properities as teh elements in what Group Group 1
Hydrogen has an electron configuration of 1s
Hydrogen's configuration is ns1
The number of teh highest occupied energy level 5
If the group number is higher than 12, the element is in which block P
Which block of elements are wedged between Group 3 & 4 in the 6th & 7th periods f-block
What is the 1st row of the f-block Lanthanides
What is the 2nd row of the f-block actinides
Group numbers are not assigned to what block F-block
