What is the periodic table and how is it structured?

The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.

How are periods organized on the periodic table?

Periods in the periodic table. In each period (horizontal row), the atomic numbers increase from left to right. The periods are numbered 1 through 7 on the left-hand side of the table. Elements that are in the same period have chemical properties that are not all that similar.

Are there 8 elements in the first period of the periodic table?

A period is a horizontal row of the periodic table. There are seven periods in the periodic table, with each one beginning at the far left. A new period begins when a new principal energy level begins filling with electrons. Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements.

What element atomic number is 8?

Oxygen
The Elements, sorted by Atomic Number

9	F	Fluorine

How was the first periodic table organized?

British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves. He arranged the elements in eight groups but left no gaps for undiscovered elements.

Why does Period 2 have 8 elements?

The elements are ordered into periods based on which electron shells are being filled (from left to right). In the second period, the second shell is being filled. And so on. There are 8 elements in period 2 because all those elements have electrons in the second shell and no electrons in the third shell.

How would you justify the presence of 1/8 elements in the 5th period of the periodic table?

When n=5,l=0,1,2,3 and 4. The order in which the enery of the available orbitals 4d,5s and 5p increases in 5s<4d<5p. The total number of orbitals available is 9. The maximum number of electrons that can be accommodated is 18, and therefore 18 elements are there in the 5th period.

How many elements are there in the 8th period?

In the 8th period, the electrons will be filled in 8s, 5g, 6f, 7d and 8p orbitals (as per Aufbau rule). So from filling 8s we will get 3 elements. After filling 5g we will get 27 more elements. After filling 6f we will get 21 more elements.

What is the meaning of period 8?

Period 8 is a row of hypothetical elements. Currently, the elements belong to systematic names. None of these elements have been discovered, and is possible that none have stable isotopes.

What are the periods of the periodic table?

The periods of the table are the rows that go from left to right. As you move from left to right there are no similarities in these elements unlike in the groups but the number of protons and neutrons increases as the masses of the elements get larger.

What are the 7 rows of the periodic table called?

The seven rows in the periodic table are known as the Periods. Each element in a particular row has the same number of electron shells surrounding the atomic nucleus. The elements hydrogen and helium have a single orbital shell; elements in the second row of orbitals have two orbital shells and so on.
