∙ 11y agoThe definition of atomic number of an element is the number of protons found in each atom of the element. Therefore, an atom with an atomic number of 5 has 5 protons.
Wiki User
∙ 11y agoTo find out how many valence electron an atom has, find the group that the element is in on the Periodic Table.
Wiki User
∙ 11y agoThe formula to determine how many electrons can be contained in an energy level is 2n2, where n is the energy level. So 2(5)2 = 50.

What is the atomic number of hydrogen and the number of its electrons in the outer shell?
The atomic number for hydrogen (H) is 1, and it has 1 electron in the 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.
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.
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.
What is the most important factor in an elements place in the periodic table?
Its elemental weight
What is the atomic number of hydrogen and the number of its electrons in the outer shell?
The atomic number for hydrogen (H) is 1, and it has 1 electron in the outer shell.
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 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.
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.
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.
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 electrons would the atomic structure of Tin have on its outer shell?
There are four electrons found on the outer shell of a atomic structure of tin. They are in a group of four.
Is the atomic number of oxygen 8 because oxygen has a second shell with 8 electrons?

How do you determine how reactive an element is based off its atomic number?
the reactivity of depends on the number of its outer shell electrons. one all outer shell electrons are there then there is little reactivity. If the atomic number is 19 then the element will 19 protons and 19 electrons. this means it has 2 electrons in the 1st shell 8 in the second 8 in the 3rd and 1 in the last. as it only has one it will be very reactive =)
What is the atomic number of helium's outer shell?
The outer shell of helium does not have an atomic number, that number belongs to helium itself whose atomic number is 2.
Does argon has the same number of electrons in its outer shell as magnesium metal?
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
