What is the number of valence electron for all the elements in periodic table group 1A 1?
One valence electron.
What is the number of valence electrons in group one?
Valence electrons are the electrons in the furthest electron shell from the nucleus.For the first three rows, essentially, the number of valence electrons is the number of squares the element is away from the beginning of the row at the left.For example. Sodium is the first (group 1) it has 1 valence electron. Magnesium is the second, it has 2 valence electrons.
How do you determine the number of valence electrons if you know the group no of elements?
valence electrons are electrons at the outermost shell as we all know, group in PE can be determined by looking at the valence electron thus if it is in group 1..then the valence electron is 1
How do you find the number of valence elections?
To find the number of valence electrons for an atom, you need to look at its electron configuration. The valence electrons are the electrons in the outermost energy level of an atom. You can determine the number of valence electrons by looking at the electron configuration or the periodic table. For main group elements (Groups 1, 2, 13-18), the number of valence electrons is given by the group number. For example, group 1 elements have 1 valence electron, group 2 have 2 valence electrons, and so on.
What is the number of valance electrons in atoms from alkali metals?
they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.
What is the number of valence electrons for the elements in group 1?
The elements in Group 1 have one valence electron in their outermost s orbital.
What number tells you the number of valence electron?
group number
How would you find valence electrons in a periodic table?
the group number of the periodic table shows the valence electron. such as :- sodium is placed in group 1 and have valence electron.
What is the number of valence electron for all the elements in periodic table group 1A 1?
One valence electron.

Elements within a group have similar number of?
electron valence hh
How do you determine the number of valence electrons if you know the group no of elements?
valence electrons are electrons at the outermost shell as we all know, group in PE can be determined by looking at the valence electron thus if it is in group 1..then the valence electron is 1
Are periods valence electrons or electron shell?
The period tells you the valence ELECTRON SHELL (energy level). The group tells you the number of valence electrons.

The atoms of the elements in Group 2 have the same?
number of valence electron
How many valence electron are in potassium?
Just 1 valence electron in K (number 19, period IV, group 1)(Its electron configuration is 4s1, in which 4:means shell number 4, s: means s-orbital, 1: means 1 electron)4s1your answer is one valence electron
Which number tells you the number of valence electron?
Indirectly this can be derived from the number of the group in the periodic table.
