How many elements are there in long period and short period?

How many elements are there in long period and short period?

The first period is the shortest period containing only 2 elements. The second and third periods are short periods. The population of each short period is eight elements. The fourth and fifth periods are long periods and contain 18 elements each.

How many elements are in the shortest period?

Period 1 is the shortest period with only two elements (hydrogen and helium). Therefore, The number of elements present in the shortest period is two.

How many elements are in long periods?

The very long period of 32 elements results from the completion of the 4f subshell of 14 electrons, the 5d subshell of 10 electrons, and the 6s, 6p octet. The filling of the 4f orbitals corresponds to the sequence of 14 lanthanoids and that of the 5d orbitals to the 10 platinum-group transition metals.

How many elements are there in 7th period?

32 elements
The seventh period contains 32 elements, tied for the most with period 6, beginning with francium and ending with oganesson, the heaviest element currently discovered.

What element is in period 4 Group 12?

zinc group
zinc group element, any of the four chemical elements that constitute Group 12 (IIb) of the periodic table—namely, zinc (Zn), cadmium (Cd), mercury (Hg), and copernicium (Cn).

What is long period in chemistry?

In chemical bonding: Arrangement of the elements. The horizontal rows of the periodic table are called periods. Each period corresponds to the successive occupation of the orbitals in a valence shell of the atom, with the long periods corresponding to the occupation of the orbitals of a d subshell.

Which period of periodic table is shortest?

How many elements are there in 5th period?

18 elements
The fifth period contains 18 elements, beginning with rubidium and ending with xenon.

Which is the shortest period in the periodic table of elements?

In the long form of periodic table, the first period has 2 elements, second and third have 8 elements; fourth and fifth have 18 elements and sixth period has 32 elements with seventh period being incomplete. Thus the shortest among these is first period. Hence correct answer is first period. Was this answer helpful?

How many elements are there in each period?

The first period is the shortest period containing only 2 elements.The second and third periods are short periods. The population of each short period is eight elements. The fourth and fifth periods are long periods and contain 18 elements each.Sixth period is the longest and contains 32 elements in it.Seventh period is the incomplete period.

READ ALSO:   Is Riverdale a good series?

The periodic table of the elements contains all of the chemical elements that have been discovered or made; they are arranged, in the order of their atomic numbers, in seven horizontal periods, with the lanthanoids (lanthanum, 57, to lutetium, 71) and the actinoids (actinium, 89, to lawrencium, 103) indicated separately below.

How many noble gases are there in periodic table?

The six noble gases—helium, neon, argon, krypton, xenon, and radon—occur at the ends of the six completed periods and constitute the Group 18 (0) group of the periodic system. It is customary to refer to horizontal series of elements in the table as periods and vertical series as groups.
