Concept explainers
Interpretation: The given table needs to be completed.
Concept introduction: A table in chemistry, where all elements are arranged by increasing
Answer to Problem 7RQ
The required table:
Name | Symbol | Atomic Number | Metal or Non-metal | Family |
Lithium | Li |
| Metal | Alkali metal |
Bromine | Br |
| Non- metal | Halogens |
Krypton | Kr |
| Non-metal | Nobel gas |
Magnesium | Mg |
| Metal | Alkaline earth metal |
Copper | Cu |
| Metal | Transition |
Explanation of Solution
Protons are defined as a positively charged
The periodic table is a very useful way to arrange elements. In a periodic table, the border line between the metals and non-metals are defined as “stair-step” line. Elements that are on the right side of stairs, called non-metals and elements that are on right side of stairs, called metals. Elements along the stair-step line are known as metalloids.In the periodic table vertical columns are known as families.
By using the periodic table is given below:
Name | Symbol | Atomic Number | Metal or Non-metal | Family |
Lithium | Li |
| Metal | Alkali metal |
Bromine | Br |
| Non- metal | Halogens |
Krypton | Kr |
| Non-metal | Nobel gas |
Magnesium | Mg |
| Metal | Alkaline earth metal |
Copper | Cu |
| Metal | Transition |
In a periodic table, elements are divided according to their chemical behaviour.
