Periods (across the periodic table) have increasing Atomic Mass. Groups (down the table) have similar properties and reactive natures.
What else can I help you with?
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.
What is the North America Convention Periodic Table?
The North America Convention Periodic Table is a variant of the traditional periodic table that places the lanthanides and actinides separately at the bottom of the table, rather than within the main body of the table. This arrangement is done to reduce the width of the table and make it easier to read.
What is the pattern of the periods on the periodic table?
I hope I'm not too late! On the left side, the atoms are smaller and as you go across they get bigger but this pattern works like a typewriter... when you get back to the left again they start out small and grow again and so on. on the top, the atoms are less radioactive. Guess what goes on in the bottom? Duh, very radioactive. Hope I helped!!!The rows in The Periodic Table of Elements, as you read it, the rows are considered to be a different period. ( Period-ic Table.) Elements have something in common if they are in the same row. All the elements in a period or row have the same number of atomic orbitals. All the elements in the top row (first period) have one orbital for its electron. The second row (second period) has two electrons orbiting. The columns have special names and rules too. A column is called a group. The elements in a group have the very same number of electrons in their outer orbital. Every element in group one has one electron in its outer shell. (and so on.)Hope it helped. I copied it from my Periodic Table Essay for school.The above answer is also correct. I am just specifying.
Why are two rows of the periodic table taken out?
The two rows at the bottom of the periodic table are taken out to make the table more compact and easier to read. These two rows are known as the lanthanides and actinides series. They are removed and placed below the main table to avoid making the entire table wider than it is tall.
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
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
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.
Why don't atoms simply get larger as you read across the periodic table?
Atoms do not simply get larger as you move across the periodic table because the increase in positive charge in the nucleus is accompanied by an increase in the number of electrons, leading to increased electron-electron repulsions that can counteract the increased nuclear charge. Additionally, the increase in effective nuclear charge (Zeff) across a period can cause the electrons to be pulled closer to the nucleus, reducing the size of the atom.
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.
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 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 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 many protons have in ironwhat is the atomimc number of protons in iron?
Read the periodic table of elements:26
