How can an atom that has 5 valance electrons achieved a full valance of electrons?
it was to gain 3 more valence electrons so it can be like the noble gases.
What element has more valance electrons than oxygen fewer valance electrons than neon more protons than sodium but fewer prtons than argon?
Chlorine
Do ions have an unusual number of electrons?
Cations donate electrons from their valance shell, have less, to reach their octet state. Anions accept electrons into their valance shell, have more, to reach their octet state.
Which particles of the atom participate in the formation of chemical bonds?
electrons. More specifically, valance electrons
How is the reactivity of elements related to valence electrons in atoms?
Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.
Why silicon has more barrier potential than germanium?
Due to variation in energy gap between valance band and conduction band....
Why does sulfur have a valency of 4 and 6 when it needs only 2 electrons for stable configuration?
It has 6 electrons in it's valance shell and needs 2 more electrons in it's valance shell to become stable. Some atoms, phosphorous for instance ( valance # 5 ), can reach deeper into their valance shell and make additional covalent bonds.
What does electro negativity of an element indicate?
How much an element is attracted to receiving valance electrons. The more electronegative, the more it needs electrons.
How many valance electrons does the oxygen have?
six valence electrons.....It only requires two more to complete octet....
What is the electrons involve in chemical bond?
The answer is Valance Electrons. Electrons are negatively charged particles which exist in atoms. See link for more detail.
Why silicon has low leakage of current as compared to germanium?
Each has four valence electrons, but germanium will at a given temperature have more free electrons and a higher conductivity. Silicon is by far the more widely used semiconductor for electronics, partly because it can be used at much higher temperatures than germanium.
Is oxygen more reactive then the noble gases?
Yes. The noble gasses are very stable because they have 8 valance electrons. They rarely react. However, oxygen only has 6 valance electrons, so it wants two more. It will most likely react with a group II metal to gain the 2 electrons.
