Atomic radius goes on decreasing while going from left to right in a period. Give reason. Atomic radius goes on decreasing while going from left to right within a period. Explain the following : i Nonmetallic character increases in going from left to right in a period. Atomic radius increases while going from left to right within a period.

Metallic character goes on decreases from left to right

Metallic character of elements decreases from left to right in a period while it increases while in moving down a group. The metallic character of elements decreases from left to right in a period while it increases while moving down a group because,. Assertion: Metallic characters of the elements increases down group while non-metallic character decreases. Reason: Down the group electron releasing tendency of the element increases while their electron accepting tendency decreases. Byju's Answer. Open in App. The metallic character of elements decreases from left to right in a period while it increases while moving down a group because, Metallic character decreases while we move from left to right while non metallic character increases. This is due to an increase in ionization enthalpy and electron gain enthalpy due to an increase in effective nuclear charge. And metallic character increases while we move down the group because electron shielding causes the atomic radius to increase, thus the outer electrons ionize more readily than electrons in smaller atoms. Give scientific reasons: 1. Atomic size increases down the group. Metallic character decreases from left to right in a period.

AOC Material Assistant. In addition, the atomic radius increases going down a group, placing the outer electrons further away from the nucleus and making that electron less attracted by the nucleus.

The metallic character of an element is defined as the easiness of its atom in losing electrons. According to the modern periodic table , the metallic character of an element decreases while moving from left to right across a period. This happens due to the fact that while moving from left to right in a period, the number of electrons and protons in an atom increases which causes an increase in nuclear force on the electrons and hence losing electrons becomes difficult. Metallic character increases down the group, and this happens because while moving down the group, atomic radius increases, making it easier to lose electrons. Most of the transition elements exhibit the typical metallic properties such as lustre, malleability, ductility, high tensile strength, high thermal and electrical conductivity, etc. We have Zn, Cd, Hg and Mn which are exceptions in this case; the rest of the elements show one or more metallic characters at normal temperatures. Apart from the metals which are exceptions, the rest of the elements are hard and possess low volatility. Transition elements show metallic character as they have low ionisation energies and have several vacant orbitals in their outermost shell. This property favours the formation of metallic bonds in the transition metals, and so they exhibit typical metallic properties.

Assertion A : Metallic character decreases and non-metallic character increases on moving from left to right in a period. Kolkata Police SI. Print Page Previous Next. Bihar LRC Clerk. The metallic character goes on decreasing while going from left to right in a period because the tendency of atoms of the elements to lose electrons or gain electrons changes in a period. Gujarat High Court Peon. So elements in the bottom-left corner of the periodic table have the highest metallic characters because they are more likely to be reactive and will give away electrons.
