What element has 4 period shells?
Explanation: Scandium atomic number 21 is in the fourth period. s, p and d .
What are the uses of Group 4 elements?
In contrast to the elements of group 3, the group 4 elements have important applications. Titanium (melting point = 1668°C) is often used as a replacement for aluminum (melting point = 660°C) in applications that require high temperatures or corrosion resistance.

What elements are in the fourth period?
The period 4 transition metals are scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), and zinc (Zn).
What is period in chemistry?
A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor.
How many elements are present in 4th period?
18 elements
The fourth period contains 18 elements beginning with potassium and ending with krypton – one element for each of the eighteen groups.

Are there any period 4 elements in the periodic table?
Period 4 element. The fourth period contains 18 elements, beginning with potassium and ending with krypton. As a rule, period 4 elements fill their 4s shells first, then their 3d and 4p shells, in that order; however, there are exceptions, such as chromium .
What are the physical properties of period 3 elements?
ATOMIC AND PHYSICAL PROPERTIES OF THE PERIOD 3 ELEMENTS This page describes and explains the trends in atomic and physical properties of the Period 3 elements from sodium to argon. It covers ionisation energy, atomic radius, electronegativity, electrical conductivity, melting point and boiling point.
What is the first ionisation energy of period 3?
The first ionisation energy is the energy required to remove the most loosely held electron from one mole of gaseous atoms to produce 1 mole of gaseous ions each with a charge of 1+. It is the energy needed to carry out this change per mole of X. The pattern of first ionisation energies across Period 3.
Which is the most poisonous element in period 4?
Arsenic (As) is an element in period 4, between germanium and selenium. Arsenic, as mentioned above, is often used in semiconductors in alloys with germanium. Arsenic, in pure form and some alloys, is incredibly poisonous to all multicellular life, and as such is a common component in pesticides.
