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.
As you move across a period of the periodic table from left to right what happens to the number of protons contained by each element?
I hate Chemistry!!!!!!!!!!!!!!!!!The number of protons increases as you go across a period.
What are patterns in the periodic table?
These are the patterns of the periodic table across the period. 1. The atomic radius reduces as we move across a period from left to right, 2. The ionization energy increases as we move across a period. 3. The electron affinity decreases as we move across a period. Learning them enables us to have a clear view of elements in the periodic table.
Does elements on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
What is the trend in electronegativity and ionization energy as you go down a row or across a period?
Electron configuration is the arrangement of elements according to their increasing atomic numbers whiles period is the arrangement of elements according to the increasing number of valence electrons.
How does electronegative vary across a periodic?
The electro-negativity of elements increases as you move across a period.

How do the metallic properties of the elements change as you move from left to right on the periodic table?
Metallic character decreases as we move across a period. The electronegative character increases as we move across a period. So the element across the period will be non mettalic in nature.

What do you notice about the number of valence electrons as you move from left to right across a row or period?
The number of valence electrons increases from left to right across a period.
What happens to the atomic number as you move across a period?
.The atomic mass increases

What do you notice about the number of as you move from left to right across the period in the periodic table?
it increases
What are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
How do physical properties differ as you move across a period or down a group?
Moving down a group, the elements will have the same number if valence electrons. Tis will give them similar properties, such as the Noble Gases, or the extreme reactivity of Group I metals. Moving across a period, elements will begin to resemble each other less and share fewer properties the further apart they are in the row.
What increases as you move right across a period in the periodic table?
Atomic number, ionization energy and electronegativity
Why do the properties of elements of change in a regular way across a period?
Because certain groups have different characteristics, so when you move to a different group the characteristics will be different.
