What is the atomic number of F plus the atomic number of An equals the atomic number of this elements?
There is no element whose symbol is An.
What are three elements whose atoms are likely to form bonds?
Helium, neon and argon are the least likely elements to form compounds.
Do horizontal rows on the periodic table have the same amount of protons or same number of electron shells?
Atoms whose symbols appear on a single row of a periodic table have the same number of electron shells. (Atoms with different numbers of protons represent different elements.)
Whose atomic number is 79?
gold is a metal element. atomic number of it is 79.
What are the elements called 'semiconductors'?
the elements whose conductance increase with increase in temperature. E.g silicon. It is insulator at 0 kelvin but on increasing temperature the loose valence electron start flowing.
What is the atomic number of F plus the atomic number of An equals the atomic number of this elements?
There is no element whose symbol is An.
How does the number of the outer energy level electrons relate to the properties of elements?
Elements whose atoms have the same number of outer electrons have similar properties..
How does the number of outer energy level electrons related to the properties of elements?

What is a bignum?
A bignum is a number whose digits of precision are limited only by available memory.
Whose opportunities were limited?

Whose powers is limited by the system of checks and balances?

Do atoms have neutrons in them?
Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.
Radioactive elements include all those elements whose nuclei contain what?
Radioactive elements include all elements whose nuclei either:contain protons more than 83 proton, orcontain neutron to proton ratio out of the stability ratio.refer to related question below.
Why do we say there is a finite number of elements in the universe?
A little more than 100 different elements have been discovered (naturally or synthesized in particle accelerators). The more massive elements are all radioactive and have progressively shorter halflives as the mass of their atoms increases. Elements have already been synthesized that exist for such a short time after their formation that they cannot be detected directly, only by the products of their decay to less massive and more stable elements. At some point it is simply not going to even be possible for elements whose atomic mass is greater than some amount to even exist.
An absolute monarch is a monarch whose power is not limited by a what?
Parliament
What does the term 'closely held corporation' mean?
Closely held corporation is referred to a company whose shareholders are of a limited number. Its stock is traded on occasion but not on a regular basis.
