Why is an element's placement on the periodic table important?

Answer 1

Elements are arranged left to right, and top to bottom in order of their increasing atomic number(number of protons), order generally coinsides with the increasing Atomic Mass. The different rows of elements are called periods. The period number of an element signifies the highest energy level an electron in that element occupies (in the unexited state). The number of electrons in a period increases as one traverses down the Periodic Table; therefore as the energy level of the atom increases, the number of energy sub-levels per energy level increases. One can tell if an element is metal, non-metal, or semi-metal just by looking at the placement on the periodic table.

Answer 2

element is especially significant in this passage?

Answer 3

What type of element, how reactive the element is, element state

Answer 4

electronic configuration is important for the matter to be stable or octet to be complete

Answer 5

because the number of electrons make some atoms bond easier. to achieve a balanced (even) number in the valance

Answer 6

It's not. You'll never need it.
