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.
How does electronegative change going down and across the periodic table?
Electronegativity increases across (left to right) the periodic table and decreases on going down.
What is the left to right rows on the period table called?
Left to right are columns: rows go up to down!
What are the rows of a periodic table called?
As with any grid, the periodic table has rows running left to right, and columns running up and down. The rows are called PERIODS and the columns are called GROUPS.
When you read across a row on the periodic table what happens?
Periods (across the periodic table) have increasing atomic mass. Groups (down the table) have similar properties and reactive natures.
Which way to rows go?
THEY GO ACROSS NOT UP AND DOWN. THAT IS FOR COLUMNS.
Do columns go across?
No that would be rows. Columns go down.
How the density properties generally change as you go down the columns of the periodic table?
The density properties generally change as you go down the columns of the Periodic Table by increasing.
Which direction are families on the periodic table?
groups on the periodic table are the vertical coumns that go up and down. A period on the periodic table are the rows that go horizontal or across.
When reading a number chart which are rows and which are columns?
Rows go across and columns go up and down.
Was Mendeleev's periodic table read horizontally or vertically?
His original 1869 table had the atomic weights increasing down columns, and family members alongside each other in horizontal rows. His revised and greatly improved 1871 version had atomic weights increasing across rows, and element families in vertical columns, essentially similar to the way a modern Periodic Table is presented.
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.
How many up and down rows does the periodic table have?
The periodic table has 7 rows and 32 columns.
What are the columns going up and down on the periodic table called?
It is called a group
How the melting temperature properties generally change as you go down the columns of the periodic table?
The melting temperature properties generally change as you go down the columns of the Periodic Table by decreasing for metals and increasing for non-metals.
How does electronegative change going down and across the table?
Electronegativity increases across (left to right) the periodic table and decreases on going down.
How does electronegative change going down and across the periodic table?
Electronegativity increases across (left to right) the periodic table and decreases on going down.
