Elements within the same row have the same electron configurations in their valence shell.
Elements in the same period show trends in atomic radius, ionization energy, electron affinity, and electronegativity.
The difference between the relationship of elements in a group or period is that the group they are labeled by a number at the top of the column and for period, the properties of elements change in a predictable way from one end of a period to the other.
Group - similar reacting properties. SIMILAR not identical
Period - ever increasing proton number
Answer 2:
elements in the same period have the same amount of energy levels (in which electrons orbit around the atomic nucleus)
elements in the same group have the same number of valance electrons (which are found in the outer most energy level)
Groups are vertical and periods are horizontal. Hydrogen and Helium are the only two elements in period 1, but hydrogen is in group 1, while helium is in group 18 (or 8A, when the groups of transition elements are not counted).
Horizontal rows are referred as periods.
Vertical columns are referred as Groups.
the difference between groups (also known as families) and periods is: a group is a column and a period goes across the table remember that
Sodium and sulfur are two distinct elements that are located in the third period in the periodic table. Sodium is a metal and sulfur is a non metal.
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
A period on the periodic table is a row.This is the horizontal section of the periodic table.
Increasing with: (but it isn't very regular)increasing period number (lower in Periodic Table, period 2 -> 6 )decreasing group number (more left in Periodic Table, group 13 -> 1)So 'Left&Low' is fastest Cesium,
the difference between groups (also known as families) and periods is: a group is a column and a period goes across the table remember that
The difference between a period and a group is that:A periodic is a horizontal row of elements in the periodic table, which simply means the column of the periodic table.A group is a vertical row of elements in the periodic table, which simply means the row of the periodic table.
In chemistry, none! the period table does not exist one can only find the periodic table although the rows of the periodic table are called periods or series. !
Short period comets have a period of less than 200 years Long period comets have a period of more than 200 years.
The shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.
FOR THE SIZEthe elements on the periodic tabledecreases across the periodand increases down the groupFOR THE ELECTRON DIFFERENCEFor the first 20 elementacross the period the difference between two closes element is +1 eletron or -1 eletrondown the group the difference between two closes element is +8 eletron or -8 eletron
I will not do your homework for you. During Spanish period, religion is the core curriculum while during the American period, the separation of church and state.
A periodic sentence contains a period at the end of the sentence, while a cummulative sentence contains several commas, as the latin word cummus translated into comma in 800 A.D
Sodium and sulfur are two distinct elements that are located in the third period in the periodic table. Sodium is a metal and sulfur is a non metal.
A period are the rows going across on a periodic table, a group is the rows going up and down. there is no relation in them.
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
Nickel is a natural element and technetium is an artificial element.For example technetium is placed in the group 7 and period 5 of the periodic table and nickel is placed in the group 10 and period 4 of the table.
