How many electrons are found in the valence shell of a sodium atom?
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
How many electrons does sodium have in its outer most 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.
How many electrons are in valence shell of a sodium atom before and after reaction with chlorine gas to give sodium chloride NaCl?
A sodium atom has 1 electron in its valence shell, while a chlorine atom has 7 electrons in its valence shell. When sodium reacts with chlorine to form sodium chloride, the sodium atom loses its 1 electron to achieve a stable octet configuration, while the chlorine atom gains this electron. The resulting sodium chloride molecule has 8 electrons in the valence shell of the chlorine atom.
How many electrons are in the outermost shell for sodium and cesium?
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
How many valance electrons dose a sodium atom have?
Since sodium has atomic number 11, its electronic configuration is untill 3s1. This means the valence shell has 1 electron, so it has 1 valence electron.
What role do valence electrons play in whether an atoms bond to another atom or not?
They play a HUGE role. This is because this is the most fundamental principle that governs chemical reactions. For example, the classic tablesalt compound. Sodium (Na) has a single valence electron, while Chlorine (Cl) has seven valence electrons. Elements of this size (atomic mass) usually want to have a total of 8 valence electrons. Well guess what? Sodium wants to get rid of that bothersome electron to have a complete shell rather than another incomplete shell. Chlorine wants to fill its shell so it happily takes it. Now Sodium has a filled shell and so does Chlorine. This means that sodium is positive and the chlorine is negative and so they bond from the difference in charge. Voila we have tablesalt. This is just one of many examples showing the importance of valence electrons in chemistry. This was an example of an ionic bond because an electron was completely given and not shared like in a covalence electron. The term "covalence" implies that the valence electrons will co-exist between the atoms, like in water (H20).
How many electrons do silicon atoms have?
14 electrons. 2 electrons in the first shell, 8 electrons in second shell, and 4 electrons in the valence shell.
How many electron dots does sodium have?
The valence shell of sodium has one electron.
Generally a complete valence shell holds how many electrons.?
Generally, a compete valence shell holds EIGHT electrons.
How many valence shell are in Yb?
One valence shell
How many atoms are stable with valence electrons?
you would need a full outer shell so 8
How many electrons are in a completed valence shell of most second period atoms when they combine with other atoms to become molecules?
Most second period atoms have four valence electrons when they combine with other atoms to form molecules.
