H and He are in the first period. Li Be, B, C, N, O, F, Ne are in the second and so on.
A period is one row across on the Periodic Table
What else can I help you with?
What does a period on the periodic table tell us?
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
What to all of the elements in period three have in common?
All the elements in third row have 3 shells. The electron enters in the third shell for all the groups.
What is the difference3 between a family of elements and elements in the same period?
a family is a column of elements a period is a row of elements
Are any of the elements in the same family also in the same period?
In the Periodic Table Of Elements, elements are not necessarily similar under the same period. But, they are similar under the same group. they only have one thing in particular they have the same amounts of shells for the atoms
What is the group of 17 elements is called?
A group of 17 elements is called a period in the periodic table. This period corresponds to the number of electron shells in an atom within that group. Elements in the same period have the same number of electron shells.
What is the similarity that the elements in the same period have?
Elements in same period have same shell. The electron enters outermost shell.
Which periods have the same number of elements?
Period 4 and period 5 of the periodic table have the same number of elements. There are 18 elements in each period. While some elements in period 4 are calcium, iron, and zinc, elements in period 5 are tin, antimony, and iodine.
What does a period on the periodic table tell us?
Elements in the same period has same number of valence shells.There are 7 periods in Periodic Table.
What to all of the elements in period three have in common?
All the elements in third row have 3 shells. The electron enters in the third shell for all the groups.
What are elements in the same?
All elements in the same horizontal row of the Periodic Table are in the same period, there are 7 periods.
What is the difference3 between a family of elements and elements in the same period?
a family is a column of elements a period is a row of elements
What is special about a period on the periodic table?
all elements in a period all have the same amount of shells example: all elements in period 1 has only 1 shell all elements in period 2 has 2 shells so the period number is the same as the number of shells in that period
What are elements in the same column called?
the period
What elements in the same column called?
the period
Elements in the same period on the periodic table are very similar to each other?
Yes, elements in the same period on the periodic table have the same number of electron shells. This results in similar chemical properties among the elements in the same period, as they have comparable electron configurations.
A horizontal row of elements is called a?
On the Periodic table, horizontal rows are given the technical term "periods", while vertical columns are called "groups". Elements in the same period are similar in that they have the same number of energy levels.
Are any of the elements in the same family also in the same period?
In the Periodic Table Of Elements, elements are not necessarily similar under the same period. But, they are similar under the same group. they only have one thing in particular they have the same amounts of shells for the atoms
