For group 1 elements : lithium , sodium, potassium...etc
All of them have one valence electrons , however Rubidium(Rb) have two valence electrons. Therefore, Cesium have one valence electrons. :D
As a neutral atom, sodium possesses 1 electron in its outermost (3rd) energy level. As a 1+ ion, it possesses 8 electrons in its second energy level, forming an octet, which is the optimum number of electrons for sodium to possess in its outermost energy shell.
There are 2 electrons on the outermost shell of calcium.
Sulphur has 6 electrons in its outermost shell.
Electrons in the outermost shell are called valence electrons.
Electrons in the outermost energy shell (valence shell) have the most energy.
Well, all the halogens have 7 valence electrons, the ones in the outermost shell, so elements like fluorine, iodine, and chlorine all need 1 electron to fulfill their octet and become stable.
As a neutral atom, sodium possesses 1 electron in its outermost (3rd) energy level. As a 1+ ion, it possesses 8 electrons in its second energy level, forming an octet, which is the optimum number of electrons for sodium to possess in its outermost energy shell.
sodium does not have a deficiency of electrons but has an extra electron in its outermost shell,which it loses to form an ionic bonds.
the valence shell is the outermost shell of an atom that has free electrons for taking part in chemical reactions... the valence shell of sodium has one free electron
Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.
thallium has 3 electrons in outermost shell.
There are 2 electrons on the outermost shell of calcium.
Sulphur has 6 electrons in its outermost shell.
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
Electrons in the outermost shell are called valence electrons.
Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.
Electrons in the outermost energy shell (valence shell) have the most energy.
