Who used the world element for the first time and who gave the experimentally useful definition of an element?
The term "element" was first used by the ancient Greek philosopher Empedocles around 450 BCE, referring to fundamental substances like earth, air, fire, and water. However, the modern, experimentally useful definition of an element as a pure substance that cannot be broken down into simpler substances was developed in the late 18th century by Antoine Lavoisier. Lavoisier's work laid the foundation for modern chemistry and the understanding of elements in terms of their atomic structure.

Who stated modern definition of chemical element first?
The modern definition of a chemical element was first proposed by English chemist Robert Boyle in the 17th century. He defined an element as a substance that cannot be broken down into simpler substances by chemical means.
Who determined the value of the universal gravitational constant experimentally for the first time?
Cavendish
What is the rate of change of free fall acceleration when an object is released into a free fall and can it be verified experimentally and how?
Take a position equation found experimentally, s(t), and take a double derivative. The first d/dx is velocity and the second is acceleration.
What is the first element of berkelium?
Berkelium is a chemical element, not first or second.
Which element is the first element in group 1?
If we look at the periodic table, we can see that the first element in Group I is Hydrogen.
What is definition of circular queue?
A queue is simply a FIFO i.e first in first out. In queue we've front and rear. Front is the initial or first location of the queue whereas rear indicates the last entry location in the queue. In the circular queue the location of front and rear will be the same IF the total space of the circular queue is utilized. Each element has its position no. for insertion , if we set the 5th element as the front element then after every insertion the ptr indicates the 5th element as front. in deletion, the fifth element is deleted every time it is the rear position. after deletion of an element the queue rotates and every time the rear indicates the 5th element of the circular queue. and every time the 5th location element is deleted.
The first element in a period is always an active?
That is not true. The first element in a period may be active or inactive, depending on the specific electron configuration of the element. For example, the first element in period 1, hydrogen, is not considered an active element.
What is the second element In a chemical equation?
The second element in a chemical equation is typically the element to the right in the equation following the first element. The second element will combine with the first element to form a compound or molecule.
Is carbon the first element on the periodic table of elements?
No, carbon is not the first element on the periodic table of elements. Hydrogen is the first element on the periodic table.
What is the determinant of a two-by-two matrix?
To find that, you multiply the first element of the first row by the second element of the second row. You also multiply the first element of the second row with the second element of the first row. Then you subtract the products not add them.
What element is the first element in the fourth period?
The first element in the fourth period of the periodic table is potassium (K).
What is the best definition for random sampling?
There are two equivalent definition. Definition 1: A simple random sample is one for which each element has the same probability of being included in the sample. Definition 2: A simple random sample is one where all sample of that size have the same probability of being selected. Although the words are similar, the first refers to the selection of individuals from the population whereas the second refers to the samples.
