When Mendeleev developed the first periodic table there were approximately how many elements known?
By 1869, a total of 63 elements had been discovered.
How many elements are there in any d section on the periodic table?
40
What are the group number and period of the elements in the periodic table if it has an atomic number of 40?
The group number is 2, as the element is in Group 2 of the periodic table, also known as the alkaline earth metals. The period number is 5, as it is in the 5th row of the periodic table.
What properties of elements did mendeleev list as he began to organize the elements?
Mendeleev listed the atomic weights and chemical properties of elements as he began to organize them. He noticed that elements with similar properties appeared at regular intervals when arranged by increasing atomic weight.
What element in the periodic table starts with the letter z?
There are two on the Periodic Table of Elements, both transition metals: Zinc, number 30 and Zirconium, number 40.
What are the 40 elements on the periodic table?
The 40 elements refer to the 40 transition metal elements. There are in total 118 known elements to this day.

What number is zirconium on the periodic table?
Zirconium is having atomic number 40 in the periodic table. Its symbol is Zr.
Which element in Period 5 of the Periodic Table is a transition element?
Vanadium Niobium Tantalum
What is number forty on periodic table?
Zirconium, symbol Zr, has the atomic number of 40.
What is number 40 in the periodic table?
The element with atomic number 40 in the periodic table is zirconium (Zr). It is a transition metal with a variety of industrial applications, including use in nuclear reactors and as an alloying agent in materials for aerospace and industrial purposes.
What element has 40 protons?
The element with 40 protons is zirconium, which has the atomic number 40. It is a transition metal commonly found in minerals.
How many electrons are in zirconium?
Zirconium is No. 40 in the Periodic Table. The '40' tells us the position of zirconium in the table, the number of protons in an atom , and the number of electrons in a neutrally charged atom. So the answer to you question is '40'.
