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
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.
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.
they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.
The Elements have a different Total Number of Electrons, but the same number of Valence Electrons.
To find the number of valence electrons of an element using the periodic table, you can look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
group number
Elements in group 1 (alkali metals) have 1 valence electron. This single electron is in the outermost energy level of the atom, making these elements very reactive and likely to lose this electron to achieve a stable electron configuration.

The period tells you the valence ELECTRON SHELL (energy level). The group tells you the number of valence electrons.

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
To determine the number of valence electrons in an atom, look at the group number on the periodic table. The group number indicates the number of valence electrons. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
