What is the most important factor in an elements place in the periodic table?
Its elemental weight
How many electrons are needed to complete outer shell of hydrogen?
Hydrogen is group 1 family, which is Alkali metals. Therefore, Hydrogen has 1 electron in its outermost shell. This means, it will perform +1 ion when they react. === ===
How many electrons does nitrogen require to fill its outer shell?
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
How many electrons does chlorine have in it's outer shell?
Chlorine is a chemical element with the symbol Cl and an atomic number of 17. It has 7 electrons in its outer shell.
Is the atomic number of oxygen 8 because oxygen has a second shell with 8 electrons?
No, the atomic number of oxygen is 8 because it has 8 protons in its nucleus.Oxygen has two electrons in its inner electron shell and 6, not 8, electrons in its outer shell. The fact that it has space for two more electrons before the outer shell is filled is the reason oxygen takes part in the chemical reactions that it does.

Its elemental weight
Why is chlorine in period 3?
Chlorine is in period three because that is how many outer shells it has. One period is one shell... In the First outer shell you can only hold.. 2 electrons. Second outer shell can hold 10 electrons. Third outer shell can hold 18 electron. Protons + Electrons = Atomic Number Atomic Number - Atomic Mass = Number of Neutrons in Outer Shells

How many electrons nitrogen has in its outer energy levels?
Nitrogen has atomic number = 7. The outer shell has 5 electrons, it requires 3 more electrons to complete the outer energy shell.
What is the factor that affects the atomic number in an element?
More shielding of the outer electrons by the inner electrons is the most important factor that affects the atomic number in an element. A valence electron in an atom is attracted to the nucleus of an atom and is repelled by the other electrons in the atom. The inner electrons shield the outer electrons from the attraction of the nucleus and cause the atomic radius to be larger.
How many electrons does nitrogen require to fill its outer shell?
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
How many electrons does chlorine have in it's outer shell?
Chlorine is a chemical element with the symbol Cl and an atomic number of 17. It has 7 electrons in its outer shell.
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
How many does hydrogen electrons in the outer shells?
Hydrogen has only one valence electrons.
Does helium have a complete outer shell?
Not by itself, no (that is, hydrogen is not a noble gas). A neutral hydrogen atom starts out with 1 electron, but it needs 2 electrons to fill its shell. Therefore, a hydrogen atom will often form 1 covalent bond with another atom, in order to gain that 1 extra electron it needs to fill its shell. Important note: Most elements need 8 electrons to get a full shell, but hydrogen is the exception: it only needs 2 electrons to get a full shell.
How many electrons are in the outer ring of potassium?
1 in the 4s orbital, 19 electrons in all (K has an atomic number of 19)
What element is a nonmetal with 53 electrons?
The element that has 53 electrons is Iodine (I). It has an atomic weight of 53 and is in Group 17(7) - Halogens family of the Periodic Table. It has 53 electrons in 5 shells with 7 electrons in the outer shell.
