Valence electrons are on the external shell.
A Bohr model--Indicate all the electrons in the atom,in various shells in the atom. In the form of planetary model like nucleus is the center&electrons are surrounding it. A Lewis model--Indicate only the electrons in the outermost shell in the atom. In the form of electron dot structures we can write an atom in the middle & surrounding will be the valence electrons in the form of dot's.
elements, or atoms, do not have valence numbers, they have valence orbitals (the outermost one) or valence electrons (all the electrons in the outermost orbital). you can look this up anywhere that shows the electron configuration, like your periodic table.
The halogens, group 17, have 7 valence electrons. When they form ions, they gain 1 more valence electron and become ions with a charge of 1-.
It looks like a very big stone which is made from silver basically umm yh silver stone which is just shiny. answered by a science teacher in bulmershe i hope you find this useful
Valence electrons
Valence electrons are on the external shell.
the number of valence electrons is the number group on the table its on
To find the total number of valence electrons in Li2O, we add the valence electrons of lithium (1 valence electron each) to the valence electrons of oxygen (6 valence electrons). So, Li2O has 2 (from Li) + 6 (from O) = 8 valence electrons.

Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
To find the valence electrons in an atom, look at the group number on the periodic table. The group number tells you how many valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
To find the number of non-valence electrons in an atom, you first need to determine the total number of electrons in the atom by looking at its atomic number on the periodic table. Next, subtract the number of valence electrons, which are the electrons in the outermost energy level of the atom, from the total number of electrons. The remaining electrons, which are not in the outermost energy level, are the non-valence electrons.
To find the amount of valence electrons in an atom, look at the group number on the periodic table. The group number tells you how many valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
The valence electrons are found in the outermost energy level of an atom. To determine the number of valence electrons in an element, you typically look at its group number on the periodic table (columns 1-18), with the exception of the transition metals. Elements in the same group have the same number of valence electrons.
Valence electrons in an atom are found in the outermost energy level or shell of the atom.
To find the valence electrons, you look at the periodic table. The first column (Li on down) have one. You continue this pattern until you reach the Nobel Gasses, which are very stable with 0 valence electrons. Remember not to count the valence electrons using the "d" sublevel, or the middle "carved-out" part of the table.
