Write the main aim of classifying elements. Name the basic property of
elements used in the development of Modern Periodic Table. State the
Modern Periodic Law. On
which side (part) of the Modern Periodic Table
do you find metals, metalloids and non-metals
Answers
Answer:
A. Systemetic study of all elements is the main aim of classifying elements.
B. The basic property of elements used in the Modern Periodic Table is the atomic number of the elements.
C. Modern periodic law: The Modern periodic law states “The chemical and physical properties of elements are a periodic function of their atomic numbers”.
D. The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids.
Answer:
A. Main aim to classify eliments is to study the properties of a group of elements with silimar characteristics at a time. Simply, to made the study of elements easier.
B. Basic properties of elements used in modern periodic table are the matallic nature, atomic size, number of valence electrons, no. Of shells
C. The modern periodic law states that "the properties of an element are the periodic function of their atomic numbers."
D. Metals are found on the left side of the modern periodic table.
Non metals are found on the right side of the table and
Metalloid are found between the mets and non metals, they are the borderline elements along the zig zagine which seperates metals from non metals.
I wrote it all myself. Hope it helps you :)
