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.
Sulphur has 6 electrons in its outermost shell.
Both sodium (Na) and cesium (Cs) are alkali metals in Group 1 of the periodic table. They both have one valence electron in the outermost shell. However, between the two, cesium has 3 more energy levels than sodium (sodium is in row 3, cesium is in row 6).
There are 2 electrons on the outermost shell of calcium.
Electrons in the outermost shell are called valence electrons.
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.
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.
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.
Cesium typically loses one electron to form a Cs+ cation because it has one valence electron in its outermost electron shell.
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
Sulphur has 6 electrons in its outermost shell.
Both sodium (Na) and cesium (Cs) are alkali metals in Group 1 of the periodic table. They both have one valence electron in the outermost shell. However, between the two, cesium has 3 more energy levels than sodium (sodium is in row 3, cesium is in row 6).
It has 5 electrons in its outermost shell.
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.
Sodium has one electron in its outermost principal energy level, also known as the valence shell.
There are 2 electrons in the outermost shell of strontium. Strontium has an electron configuration of [Kr] 5s^2, indicating that it has two electrons in its outermost shell.
