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 cation vary across a row and down a column of the periodic table?
According to the modern Periodic Law, atomic number affects the physical and chemical properties of an element, so the elements are arranged in an ascending order according to their atomic number...therefore, it increases by one across a row of the periodic table.
How do you find the electron configuration with two elements?
periodic table....ask someone who knows how to read one and you will get your answer iit is real simple
What are the uses of the first 20 elements of the periodic table?
The answer is too long for Wiki Answers; please read a book of general chemistry.
What is the pattern of the periods on the periodic table?
In Chemistry, periodic trends patterns in the periodic table are the tendencies of certain elemental characteristics to increase or decrease as one progresses from one corner of the Periodic table of elements.
Why don't atoms simply get larger you read across the periodic table?
because the no. of shells in the atoms across the Periodic Table remains the same
Why don't atoms simply get larger as you read across the periodic table?
because the no. of shells in the atoms across the periodic table remains the same
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 you read the periodic table horizontally what happens to the atomic number?
It is increasing consecutively.
Some say the periodic table is read like a book Explain how you read the periodic table and how this can give you information about elements in the table?
you read it from left to right
How does cation vary across a row and down a column of the periodic table?
According to the modern Periodic Law, atomic number affects the physical and chemical properties of an element, so the elements are arranged in an ascending order according to their atomic number...therefore, it increases by one across a row of the periodic table.
Why is it important to read and understand the periodic table of elements?
No one can understand chemistry without understanding the periodic table; it is the most fundamental part of our chemical knowledge.
What does the color on an element block tell me?
Read the explanations under your periodic table; not all periodic tables have colors.
What information about an atom properties can you read from the periodic table?
Different periodic tables show different information about an atom's properties. On the normal periodic table you can read the atomic number, which is the value of the number of protons in the nucleus.
How did Mendeleev create the periodic table when he knew nothing about electrons and atoms?
he read about it in the newspaper
How do the atomic numbers of the elements with in each of group 1 2 and 13-18 of the periodic table vary?
Mendeleev's Periodic Table -- the reason for periodicity -- is explained by the arrangement of the electrons around the nucleus. *Read your chemistry book* :D
What kind of elements are in the periodic table?
The horizontal rows of elements on the periodic table of elements. Periods gain one proton and one electron as you read the table from left to right.
