What properties of elements did mendeleev list as he began to organize the elements?
Mendeleev arranged the elements in the increasing order of their atomic masses and repeating properties.
What are the group number and period of the elements in the periodic table if it has an atomic number of 40?
Zirconium(Zr) has an atomic number of 40. It is in Group 4 and Period 5.
What is the atomic mass of calcium carbonate?
Calcium Carbonate does NOT have Atomic Mass. It has MOLECULAR Mass, because it is a molecule, that is a combination of three elements, calcium, carbon and oxygen. . Calcium Carbonate has the molecular formula 'CaCO3'. So from the Periodi Table of elements, we read the ATOMIC Masses for these three elements. viz. 1 x Ca = 1 x 40 = 40 1 x C = 1 x 12 = 12 3 x O = 3 x 16 = 48 40 + 12 + 48 = 100 The MOLECULAR mass of Calcium Carbonate. NB Atomic Masses only refer to elements in the Periodic Table.
What is 40 20Ca?
Ca stands for Calcium, 20 is the atomic number, and 40 is the average atomic mass
Which element has an atomic mass of 40.1?
The element with an atomic number of 40 is zirconium.

What are the group number and period of the elements in the periodic table if it has an atomic number of 40?
Zirconium(Zr) has an atomic number of 40. It is in Group 4 and Period 5.
The atomic number of potassium is?
Protons that are contained within any and all Atomic [Elemental] Nucleus / Nucleii.

The Atomic and mass number for calcium?
Calcium is a metal element. Atomic mass of it is 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 is 40 20Ca?
Ca stands for Calcium, 20 is the atomic number, and 40 is the average atomic mass
How many penny weights is in an ounce of gold?
40
What periodic element has a mass of 50.9?
Three elements (isotopes) are known to have an atomic mass of 39.96:Ar-40 (99.6%), K-40 (0.01%) and Ca-40 (96.9%).(Percentage value of naturally occurring in elements.)
Which element has an atomic mass of 40.1?
The element with an atomic number of 40 is zirconium.
What is the formula mass of CaCO3?
The atomic masses of the elements Ca, C and O are 40, 12 and 16 respectively. Accordingly, the formula mass of calcium carbonate, CaCO3 should be 40 + 12 + 3(16) = 100.
Do you round potassium to 40?
I cannot imagine rounding potassium to 40. The atomic number is 19, and the atomic weight is 39.09 ■
