What is the name of element whose symbol of Au?
[Au] is GOLD atomic mass - 196.97, and is in 79th place in the periodic table of elements
What does le stand for on the periodic table?
there is no known element whose symbol is "Le" but there is: Li (lithium), Lr (Lawrencium), Lu (Lutetium), La (Lanthium)
What have 14 Protons?
To figure this out, all you need to do is look at a periodic table. On the periodic table, locate the element whose atomic number is 14 and you have your answer. It turns out that that element is silicon.
The element whose symbolis na on the periodic table?
Sodium (from Latin natrium)
What element whose valence electrons is full with two electrons on the periodic table?
Helium
Is Oxygen existing as atom?
Yes, it is a chemical element whose symbol is O and atomic number is 8. It is a member of the chalogen group on the periodic table and is a highly reactive nonmetal and oxidising agent.
The element whose symbol is KF on the periodic table?
KF is potassium fluoride and has the elements potassium (K) and fluoride (F).
Why are things grouped together on the periodic table?
-An element is placed in that group of periodic whose group number is equal to the number of valence electrons.
How can we identify group of an element whose atomic number is given?
Yes, if a periodic table that includes atomic numbers, as most periodic tables do, is available for reference
What element in the periodic table has the least number of atoms in a water molecule?
That would be Hydrogen, whose name means, (Make water).
What element has 75 protons in period 6 of the periodic table?
At-Astatine Because it is the 85th element of the periodic table. That means that it has 85 protons and 85 electrons
Which element's symbol is Na on the periodic table?
An element in a periodic table has got a number known as atomic number. So to say the flat number (just as fun in saying) in which the particular element resides. Thus 1 is for hydrogen, 2 for helium, 3 for lithium and so. In 26, ferrous occupies. 79 is for gold and 80 is for mercury. Uranium will be located at 92. This atomic number is nothing but the number of protons in the nucleus of the atom (element). O2 is not an element. It is a gas molecule which has two oxygen atoms. O is the element whose flat number in periodic table is 8. CO2 is also a gas with the elements of carbon and oxygen. One atom of carbon and two atoms of oxygen. So far elements with atomic number 108 have been found. Diffraction of X-rays with crystals such an zinc sulphide has led to the right placement of the element in the periodic table.
