Using neon as an example explain why noble gases are unreactive?
Noble gases like neon have a full outer electron shell, making them stable and not needing to gain, lose, or share electrons with other atoms to achieve a stable configuration. This makes them unreactive because they do not easily form chemical bonds with other elements.
What is the numbers of electrons in each shell?
According to one of Lewis' theories, each shell has a maximum number of electrons using the formula 2n2 where n = the shell number. For example: 1st shell = 2(1)2 = 2 electrons maximum; 2nd shell = 2(2)2 = 8 electrons maximum.
How many unpaired electrons does krypton have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
One way to show the number of valance electrons an atom has is with what?
One way to show the number of valence electrons an atom has is through its electron configuration, specifically by focusing on the outermost shell of electrons. Additionally, the periodic table can be used, as elements in the same group typically have the same number of valence electrons. For instance, Group 1 elements have one valence electron, while Group 18 elements have eight. Another method is using Lewis dot structures, which visually represent the valence electrons around an element's symbol.
Why does the M shell in Bohr theory really contain 18 electrons while the N shell really contains 32 electrons?
The formula for getting the total number electrons occupying a shell is given by 2n2 For M shell the principal quantum number, that is, 'n' is 3. So 2 x 9 = 18 For N shell its quantum number is 4 and hence 32 electrons.

What is one of the metals that can use the inner shell before using the outer shell to bond?
Copper is an example of a metal that can use its inner shell before outer shell electrons to bond. It has a configuration of 3d104s1, and the 4s electrons are used before the 3d electrons in bonding reactions.

What are the valence electron of an atom?
The valence electrons are found on the valence shell, the outermost shell of an atom. By using the periodic table and the group numbers, one can find the number of valence electrons for elements in groups (vertical columns) 1-2 and 13-18. For the 1st 2 groups (1 and 2), the group number tells the number of valence electrons for elements which belong in that group Elements in the 1st group have 1 valence electron and elements in the 2nd group have 2 valence electrons. For groups 13-18, refer to the tens' value (the teen value that is not the "1" in these cases). Elements in group 13 have 3 valence electrons, elements in group 14 have 4 and so on to the the final group, 18, where electrons have a full octet of valence electrons.
How do you find the arrangement of electrons of titanium?
using the electron shell pyramid
How many completely full electron shells do the elements in the third row contain?
Elements in the third row of the periodic table have 3 completely full electron shells. This means they have all 8 electrons in the first shell, all 8 electrons in the second shell, and all 18 electrons in the third shell.
What does an elements location on the periodic table of elements tell you about that element?
The amount of electrons and their position in the atom is the main thing. The atomic number of an element is it's amount of protons. That makes the periods (rows). Groups are put in place using where the electrons are in the atom (how many electrons are in the outer shell of that atom). All elements in a representative element group have the same amount of electron sin the outer shell. (e.g. all elements in Group 1 have 1 electron in the outer shell)
How do you use periodic table to know the numbers of electrons available for bonding?
All of the elements, apart from the transition metals in the middle, are divided into groups. Group 1 elements have 1 electron in their outer shell, and this is the electron used in bonding. Group 2 have 2 electrons, Group 3 elements have 3, and so on. Group 8 elements have a full outer shell, so they generally don't react.
How many electrons to fill outer shell of oxygen?
Oxygen needs 2 electrons to fill it's valence shell which is why it forms a 2- ion.
How many electrons on the outer shell of a silicon?
Silicon has 14 electrons. There are four electrons that orbit the nucleus in the outermost, or "valence," energy level, which are given to, accepted from, or shared with other atoms.
How many electrons does aluuminum have in the second shell?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
How many unpaired electrons does krypton have?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
