Elements can be identified by their atoms through their atomic number, atomic mass, and chemical symbol, all of which are represented on the periodic table. The unique number of protons in an element's atomic nucleus is also identified. This information, combined with the arrangement of elements in the periodic table based on shared properties, reveals the identities of elements.
Elements are identified by their atoms through certain key properties that are represented on the periodic table. These key identifying properties include the atomic number, atomic mass, and the element's chemical symbol. For instance, in the case of carbon, its symbol (C) and name, its atomic number of six (given in the upper left-hand corner), and its atomic mass of 12.01 are displayed in its designated box in the periodic table.
Each element's unique number of protons in its atomic nucleus also helps identify an element. Additionally, the arrangement of elements in the periodic table provides insight into the elements' shared physical and chemical properties - they are arranged in a series of rows and columns based on these similarities. Atoms of elements can further combine and bond with each other in certain ways, based on these unique properties.
By the twentieth century, it was understood that these properties follow a periodic relationship with the atomic numbers, a concept referred to as the periodic law. A modern periodic table, thus, arranges the elements in ascending order of their atomic numbers and groups atoms with similar properties in the same column.

Robert Hooke
Explanation:
Answer:
Robert Hooke is the first person
Explanation:
Robert Hooke made his own microscope, which he made himself, and observed some small pieces of cork underneath it. This is where he fist viewed and named the cells.

The relative motion of a person riding in a car has been stationary with car, uniform constant with road, and sun.
The motion has been defined as the change in position of an object with respect to another.
The relative motion has been observed by considering an object at rest and assuming the displacement with the another.
The relative motion has been assessed from car, thus car has been assumed at rest.
Thus, the relative motion of a person riding in a car has been stationary with car, uniform constant with road, and sun.
