Elaborate on what can be learned about the properties by the location of element on the periodic table. use atomic number 13 as an example.

From the location of elements in the periodic table you can predict it's properties. The elements are arranged in the modern periodic table in the order of increasing atomic number. The rows are called periods and the columns, groups. ... These elements have the same number of electrons in their outermost (valence) shells.

Explanation:

atomic 13 tells us that the atomic weight which is 26.982. and the m.p. is 660 degrees celcius

Explanation:

In a periodic table, all elements are arranged as per there atomic mass.

There are various properties that can be learned from the position of an element in a periodic table.

1- The location defines the nature of the element. For example if an element has atomic number 13, the element is Aluminium and is a metal.

2- As it lies in the left hand side of the table, it shoes different characters when treated with acidic or basic solution.

3- As it lies in category of metal, we can recognize its melting point and boiling point.

4- The reactivity is also defined on the basis of group that element belongs to.

conservation of mass

mass before something happens = mass afterwards
