Question

More than four-fifth of the natural elements are?
A. Metal
B. Liquid
C. Semi-liquid
D. Solid

Answer 1

The periodic table is a list of all the elements known to man, arranged in order of increasing atomic number and recurrent chemical properties. They are arranged in a tabular format, with a row representing a period and a column representing a group.

Complete answer:
There are $118$ elements that we know of so far, with $92$ of them occurring naturally. Metals are known to make up the majority of the $92$ elements. As a result, more than four-fifth of the natural elements are metals.
The first $94$ elements of the periodic table are found in nature, but the remaining elements (numbers $95$ to $118$ ) have only been synthesised in laboratories or nuclear reactors. Every chemical element has a unique atomic number, which indicates how many protons are present in its nucleus. Because all isotopes of an element have the same atomic number, they all belong to the same column on the periodic table.
Elements are arranged from left to right and top to bottom in order of increasing atomic number. As a result, elements in the same group will have similar valence electron configurations and, as a result, chemical properties.
Elements in the same period will have valence electrons in ascending order. As a result, the number of energy sublevels per energy level increases as the atom's energy levels increase.
Hence , the correct option is A. Metal.

Note:
Every chemical element has a unique atomic number, which indicates how many protons are present in its nucleus. Because all isotopes of an element have the same atomic number, they all belong to the same column on the periodic table.
