Period four elements fill 4s shells then 3d then 4p. The first element in this particular period is potassium.
The fourth element in the fourth period is titanium (Ti).
They are:Potassium, Calcium, Scandium, Titanium, Vanadium, Chromium,
Manganese, Iron, Cobalt, Nickel, Copper, Zinc,
Gallium, Germanium, Arsenic, Selenium, Bromine and Krypton.
It is titanium.
Argon
Manganese is in the fourth period of the Periodic Table of Elements. Periods are rows, groups are columns within the Periodic Table of Elements.
This comprises all elements which have one or more electrons in their fourth shell. They comprise the fourth row of the periodic table.
Copper and nickel
Metals, to metalloids, to nonmetals
all the elements in period 1 have one energy level, all the elements in period 2 have two energy levels, all the elements in period 3 have 3 energy levels... and so on
In the Periodic Table, a group is a column of elements and a period is a row. The element in the 14th column and fourth row is germanium.
The fourth period contains 18 elements beginning with potassium and ending with krypton – one element for each of the eighteen groups. It sees the first appearance of d-block (which includes transition metals) in the table. Do You Agree? Sincerely, Jocelyn E.Flowers
In the Periodic Table, a group is a column of elements and a period is a row. The element in the 14th column and fourth row is germanium.
Manganese is in the fourth period of the Periodic Table of Elements. Periods are rows, groups are columns within the Periodic Table of Elements.
This comprises all elements which have one or more electrons in their fourth shell. They comprise the fourth row of the periodic table.
The fourth electron shell is filled by krypton. Krypton is the last element in the fourth period on the periodic table. Each of the periods represents an electron shell. Elements in the first period have electrons in the first shell; elements in the second period have electrons in the second shell; and so on.

The periods are the numbers down the left or right side that count each row, hence the fourth period is the fourth row down starting from the top row. So accordingly, five elements in the fourth period of the periodic table are K - potassium, Ca - calcium, Ti - titanium, Fe - iron, and Cu - copper.
In the Potassium's row they all contain a fourth covalent shell.
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
you say, fourth period!! hahah!!!
