Why are no two emission spectra for different elements ever the same?
Because emission spectrum are the result of the electron configuration of the element and no two elements have exactly the same electron configuration.
Why second period elements are called bridge elements?
They are called bridge elements because the 'bridge' the first two elements with only one electron shell to the rest of the Periodic Table, which have ascending amounts of electron shells. The first two are also the most abundant elements in the universe.
What two elements for example a metal and nonmetal where one gains an electron and the other looses an electron?
for example: metal-potassium nonmetal-fluorine
Two elements that have atoms of verry diffrent sizes means that the cast iorn is likely what?
Two elements that have atoms of very different sizes means that the cast iron is likely a substitutional alloy.
What is the number of valence electron for all the elements in periodic table group 2A 2?
Two valence electrons.
Which of the following elements sodium oxygen chlorine and aluminium will give out electrons and how many electrons will it accept?
Sodium lose one electron, aluminium lose three electrons.Chlorine accept one electron, oxygen accept two electrons.
What is the name of the group of elements with two valence electron in each period?
The name of the group of elements with two valence electron in each atom is "alkaline earth metals."
Why are no two emission spectra for different elements ever the same?
Because emission spectrum are the result of the electron configuration of the element and no two elements have exactly the same electron configuration.
Do Cl nd Ar have the same electron configuration?
No. No two elements have the same electron configuration.

Why only 12 elements form ions easier than the rest of the elements in periodic table?
I would imagine that these elements are hydrogen, the alkali metals and the halogens. Hydrogen and the alkali metals only have one outer electron, which is easier to displace than the two outer electrons of the alkaline earth metals, for example. In contrast, the halogens only need one more electron to have a complete outer shell; it is easier to accept one electron than the two electrons needed by the chalcogens - oxygen, sulphur, selenium etc.
Elements contains the same inside electron arrangement as phosphorus?
Two identical electron configuration doen't exist for atoms.
What elements contains the same inside electron arrangement as phosphorus?
Two identical electron configuration doen't exist for atoms.
How do elements achieve stable electron configurations between two atoms?
protons
What two entities are formed when one element transfers an electron to a different element which can accept the electron?
A positive ion ( the one that gives the electron) and a negative ion ( the one that accepts).
What is the number of valence electron for the elements in Group 8A?
Eight, except for helium which has two.
How many electron shells do the atoms of elements in the second period have?
two K and L
