What is the outer shell number for beryllium?
The number of electrons in the outer shell of Beryllium is 2.
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 =)
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.
Will atomic properties vary in a similar way in a different periods?
The atomic properties depends on the electrons of the outer shell. THe elements in differnent periods have the same arrangments of electrons in the outer shell. Thus, atomic prperties vary in a similar way in diffrent periods
How many electrons are present in the outer shell of an atom with an atomic number of 14 and an atomic weight of 29?
Atomic number is the number of protons. In a neutral atom, the number of protons is equal to the number of electrons. So, in your example, the number of electrons in this atom is 14. The first energy shell can take 2 electrons, the second energy shell can take 8 electrons, and the third energy shell can take 18 electrons. If there are 14 total electrons, 10 would be found in the first two energy shells, leaving 4 for the third energy shell.
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 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 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.
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.
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.
What is the outer shell number for beryllium?
The number of electrons in the outer shell of Beryllium is 2.

What specific properties of metals accounts for their unusaul electrical conductivity?
the number of electrons in the outer shell of each atomic particle.
How many electrons would you expect chlorine with an atomic number of 17 to have in its outer shell?
Chlorine has 17 electrons, distributed in the following way: 2 in first shell 8 in second shell 7 in third (outer) shell Therefore Chlorine 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.
