Where would an element be placed on the periodic table if it had a mass number of 304 amu, very low ionization energy, bonds easily with other elements, melting point of 50.1 degrees celsius, has the smallest electronegativity, predicatively the largest atomic radius, great metallic character, and silver in color

Explanation:

Data Given:

Predict place of element in the periodic Table having following properties

mass number = 304 amu

Ionization energy = very low

bonds = easily bond with other elements

melting point = 50.1° C

electronegativity = smallest    

Atomic radius = largest

metallic character = great

color =  silver  

Periodic Table is the table where elements were placed based on their atomic number.

In 1913 Mosley construct the periodic table according to their atomic number.

Modern Periodic Law :

the physical and chemical Properties of the elements are the periodic functions of their atomic number.

Atomic Number:

Atomic number is the number of electron or proton, denoted by Z

                Z = e or P

Atomic Mass:

Atomic mass is the number of proton plus neutron in the nucleus. it is denoted by A.

              A = P + N

Atomic number is almost half of the atomic mass for majority of the element.

Periodicity of periodic Table:

properties of the element repeat itself at certain interval.

Periodicity of Properties is as follow

1. Ionization energy:

The Ionization energy increase from left to right and decreases down the group.

2. Electronegativity:

E.N increase from left to right and decreases down the group.

3. metallic character:

Metallic character increase down the group and decrease from left to right. metals have metallic color, bristle and shiny surface.

4. non-metallic character

Non-metallic character decreases down the group and increases from left to right.

5. Melting point and boiling Point:

Melting point and boiling Point increases when the metallic character increase and decreases when the metallic character decreases.

6. Atomic radius :

Atomic Radius decrease from left to right and increases from top to bottom as shells are added.

Now keeping in mind all above points, to predict the place of the atom whose properties are given.
