Metallic character goes on decreases from left to right

The graph above indicates some trends in the U. By observing the direction our eating habits are going, steps can be taken to help prevent bad eating habits and decrease problems such as high blood pressure and heart attacks. Development of the periodic table has helped organize chemical information in many ways. We can now see trends among properties of different atoms and make predictions about the behavior of specific materials.

In the answer key it had the order P, Si, Be, Mg, Na and I was a little confused why Be wouldn't have the lowest metallic character since metallic character increases going down a group and decreases going across a period so it is higher than P and Si therefore having lower metallic character. The answer is in increasing order so P has the least metallic character and Na has the most.

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. Electronegativity increases while going from left to right within a period. How does the metallic character of elements change on going from left to right in a period of the periodic table?

Metallic character goes on decreasing while going from left to right in a period. Open in App. Verified by Toppr. 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. As we move from left to right in a period, the nuclear charge increases due to a gradual increase in the number of protons.

Metallic character goes on decreases from left to right

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.
