What are the names of the periods on the periodic table?
Periods are the elements on the periodic table that go across, in rows. So basically going across each row is called a period
Do periods go across or down?
Periods go across the periodic table. Groups go down.
Across the periodic table the properties of elements become WHAT?
across a periodic table, the properties of elements become less metallic and more nonmetallic
What happens to the properties of elements across any periodic of the table?
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
What are some good questions about the periodic table?
Some good questions about periodic table: where are metalloids placed? why group 18 elements are inactive? How many groups and periods are in periodic table? How reactivity changes across and down the group?
A row of elements across the periodic table is an?
The rows across the periodic table are called periods.
What are the names of the periods on the periodic table?
Periods are the elements on the periodic table that go across, in rows. So basically going across each row is called a period
Are columns of elements called periods?
No,Each of the columns in a periodic table represents a group.
How many rows or periods are in the periodic table?
Th horizontal rows are referred as periods. There are 7 periods in Periodic Table.
What are periods and groups?
Elements in the periodic table are arranged in periods (rows) and groups (columns). Atomic number increases as you move across a row or period. The period number of an element signifies the highest unexcited energy level for an electron in that element. Elements within a group share several common properties. Groups are elements have the same outer electron arrangement. The outer electrons are called valence electrons.
Do periods go across or down?
Periods go across the periodic table. Groups go down.
Across the periodic table the properties of elements become WHAT?
across a periodic table, the properties of elements become less metallic and more nonmetallic
What happens to the atomic number as you go from left to right across the periodic table and why does this happen?
Periods on the periodic table refer to the rows of elements. As the elements progress to the right, the atomic numbers increase, usually in steps of 1.
What is a row of elements across the periodic table called?
The rows going across the periodic table are called periods. As you go across a row, each element increases in number of protons and electrons, which distinguishes it from other elements in the table.
What is difference between group and period in periodic table?
Groups are vertical columns on the periodic table consisting of elements with the same number of valence electrons. Periods are horizontal rows with elements sharing a highest unexcited electron energy level.
What happens to the properties of elements across any periodic of the table?
Across any period, the properties of elements gradually change. This gradual change is called a periodic trend.
What is the difference between a period and a group on the periodic table?
Periods on the periodic table go across and are based on the number of unexcited electrons increasing as you read across. Groups on the periodic table are read down the table and share the same number of valence electrons.
