How does the arrangement of the electrons change as you move down the columns?

the number of electrons changes with the number of protons, and the number of protons = the atomic # (represented with "Z"). The numbers increase by 1 each step to the right, then continues each row down.

FACTORS ENHANCING THE INCREASE IN GAINING OF ELECTRON
1.increase in charge
2.constant screening effect
3.increase in electron affinity
4.increase in elecronegativity

When making a table do the columns go across or down?
Up and down.
What happens when ionization energy change when moving down a group of elements?
the ionization energy is increased because of electronegativity when we move down the group the electronegativity is decrees who hold all electrons hardly to gather that's why the electrons loose easily and become an ion.
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.
When moving down a group ( family) in the periodic table the number of valence electrons?
When moving down a group, the number of valence electrons do not change. This similarity yields the elements in the same groups to have same chemical properties. For example, elements in group 17 obtain one electron to stabilize as -1 ion.In a group, all the elements have a same number of valence electrons. So their chemical properties are equal. But the physical properties vary.Valence electrons are the electrons in outermost shell.The valence electrons remain same in a group. For example-Group-1 elements have 1 valence electron.
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.
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.
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.
What is a period in a periodic table?
a row going acrossNOT to be confused with groups or families which go down in columns and have to do with valence electrons
How does a motions arrangement of particles change as a substance freezes?
The motion slows down, and the arrangement normally packs closer together.
Do columns go across?
No that would be rows. Columns go down.
Which way to rows go?
THEY GO ACROSS NOT UP AND DOWN. THAT IS FOR COLUMNS.
What direction are columns in Excel?
Columns are vertical, so they go up and down.
How does columns run in Microsoft Excel?
Columns are vertical cells (they run up and down).
Rows go up and down?
No - columns go up and down.
When making a table do the columns go across or down?
Up and down.
Are columns up and down or side to side?
Usually up and down.
When reading a number chart which are rows and which are columns?
Rows go across and columns go up and down.
