As you move to the right across a p Ans. Due to its lightweight metal properties, it is used structurally in the aerospace industry. The many radioisotopes that are not found in nature have been characterized after being artificially made. It was used extensively as such by American publications before the international standardization (in 1950). If an element has isotopes that are not radioactive, these are termed "stable" isotopes. In 1661, Robert Boyle proposed his theory of corpuscularism which favoured the analysis of matter as constituted by irreducible units of matter (atoms) and, choosing to side with neither Aristotle's view of the four elements nor Paracelsus' view of three fundamental elements, left open the question of the number of elements. The groups of the periodic table are displayed as vertical columns numbered from 1 to 18. This clarification has increased the value of the law, which is used as much today as it was at the beginning of the 20th century, when it expressed the only known relationship among the elements.
