What else can I help you with?
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 is 40 20Ca?
Ca stands for Calcium, 20 is the atomic number, and 40 is the average atomic mass
What is the atomic mass of calcium carbonate?
The atomic mass of calcium carbonate (CaCO3) is calculated by adding together the atomic masses of calcium (Ca), carbon (C), and three oxygen (O) atoms. The atomic mass of Ca is 40.08, C is 12.01, and O is 16.00. Therefore, the atomic mass of calcium carbonate is 40.08 + 12.01 + (3 * 16.00) = 100.09 g/mol.
What is zirconium's atomic number?
40
When Mendeleev developed the first periodic table there were approximately how many elements known?
By 1869, a total of 63 elements had been discovered.

The atomic number of potassium is?
Protons that are contained within any and all Atomic [Elemental] Nucleus / Nucleii.
What is the atomic number for Ziconium?
Zirconium is a meta element. Atomic number of it is 40.
How are chlorine-37 and calcium-40 similar?
Chlorine-37 and calcium-40 are both isotopes, meaning they have the same number of protons in the nucleus as their respective elements but a different number of neutrons. They are naturally occurring and contribute to the overall atomic weight of their elements.
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 is 40 20Ca?
Ca stands for Calcium, 20 is the atomic number, and 40 is the average atomic mass
The Atomic and mass number for calcium?
Calcium is a metal element. Atomic mass of it is 40.

Which element has an atomic mass of 40.1?
The element with an atomic number of 40 is zirconium.
If 40 percent of the isotopes of an element have a mass of 16 atomic mass and 60 percent of the isotopes have a mass of 18 atomic mass what is the average atomic mass?
The average atomic mass can be calculated as the weighted average of the masses of each isotope, using their percentages as the weights. In this case, the average atomic mass would be: (0.4 * 16 amu) + (0.6 * 18 amu) = 6.4 amu + 10.8 amu = 17.2 amu.
