How much electrons would Phosphoruse have to gain or lose to get 8 valence electrons?
Short answer:It will have to gain three electrons to obtain a stable octet in its valence shell.The answer if you're actually looking to understand:Since the Atomic Number of Phosphorus is 15, that means that in its stable state it has 15 electrons. The first orbital will thus hold 2 electrons and the second will hold 8, both at the maximum capacity. That is a total of 10 electrons. As mentioned before, Phosphorus has 15 electrons, and so it has 5 electrons in its valence shell. The capacity of the third orbital is 8 electrons. Therefore, in order to fill the valence, Phosphorus would either have to lose its five valence electrons or pick up three. Since it will preferentially pick up the three before losing five, it will thus have to gain three electrons. (If you're looking to understand why it will pick up three rather than lose five, look up "ionization energy" and "electron affinity"
Do nonmetals become more reactive when they move left to right?
Yes. This is due to the fact that their valence shells are adding electrons, coming closer to having an octet. The halogens in group 17/VIIA are the most reactive nonmetals because they have seven valence electrons and readily react in order gain the eighth valence electron, which gives them an octet like the nearest noble gas. It takes much less energy to gain one electron or share one electron, than it does to gain or share two or more electrons.
Do metal atoms lose their electrons much more easily than nonmetal atoms?
Yes. Metals have lower electronegativities than nonmetals, and they tend to have fewer than four valence electrons, so they are more likely to lose electrons in order to achieve a noble gas configuration and become stable.
Why are the electrons in the electron transport chain important?
they assist in chemical bonding, and help you identify an atom's valence electrons (electrons in outermost shell). For example, Sulfur has 6 valence electrons. It needs to gain 2 electrons (2-) to satisfy the octet rule. If sulfur were to bond with calcium (2+) you would use these charges to bond, and your formula would look like CaS since when you cross over your charges reduce.
Is it possiable for an atom or ion to have no valence electrons?
The term valance shell refers to the number of electrons in the outermost orbit so by taking that we can consider hydrogen has no valance electrons because the hydrogen atom has only two electrons and the first electronic orbit can hold that much number of electrons in it.
How much valence electrons do berylium got?
Beryllium has two valence electrons.
How much valence elections does lanthanum have?
Lanthanum has 3 valence electrons
How much valence electrons Ne have?
8 valence electrons (so do all of the other noble gases)
How much valence electrons can any atom have?
eight I believe
How much valence electrons does sulfur have?
The element Sulfur has 6 valence electrons. : )
What are valence electron?
Valence electrons are the electrons in the outer-most shell of the atom. These are typically the electrons involved in forming bonds with other atoms (as opposed to the other so-called "core" electrons which do not interact much with other atoms or molecules.)See the Related Questions links below for more information and for how to count the valence electrons of an atom.Any electrons located in the outer shell of an atom are known as valence electrons.Valence electrons are electrons present in the outermost shell of an atom.
How many additional valence electrons does fluorine need to have a full valence?
I believe you are talking about fluorine. If you are, F needs one more electron to gain a full shell.If you go to WikiAnswers for this information, that is counterproductive, because there is a much better way to do it. Look at the periodic table. Groups IA through VIIIA tell you what you need to know. IA has one valence electron, IIA has two valence electrons etc. Fluorine is in group VIIA and therefore has seven valence electrons. All atoms want eight, and thus fluorine is in need of one more.
What is the relationship between an element's number of valence electrons and its reactivity?
When we say valence electron we mean the number of electron left it the outermost shell of element, valence electron can be positive of negetive. If an element need much electrons to be octet, that means that the element is not reactive than the one who will give out electrons, the the one who can give electrons much are less reactive than the one who can give a litle and the reaction will be normal as it is soppused to be, Eg lithium and berylium. Lithium is more reactive than berylium because lithuin has 1valence electron while berylium has 2....reactivity goes with the action of valence electron in an element
What do valence elctrons do?
They are typically the electrons which are involved in forming bonds to other atoms (as opposed to the other so-called "core" electrons which do not interact much with other atoms or molecules. (This is for WHAT they are not what they DO) (stupid answer by the way man)
How do the valence electrons tell about the reactions of different elements?
Not sure if I understand your question correctly, but some elements are more electronegative than others, so they draw in electrons better than others. For example, in NaCl, chlorine (Cl) is much more electronegative than sodium (Na) so it simply takes the sodium's extra valence electron.
How much orbitals does silicon have?
Silicon has three orbitals in its valence shell: one 3s orbital and two 3p orbitals. This gives it a total of four valence electrons.
How do you know how much valence electron an element has?
First, find the element on the Periodic Table of Elements, which is arranged in convenient columns. There are 8 numbered columns, and everyting in column one has one valence electron, everything in column two has two valence electrons, and so forth; column eight is an exception because eight valence electrons really means none (since valences operate on the principle of every atom reacting in a way that will give it eight electrons, either all its own or shared). However, not all elements are in these numbered columns. There are also the transition state elements. Those elements have several possible valences, due to the complexity of their electron shells, in which some of the electrons in the inner shells participate in chemical reactions, as well as the usual outer electrons. But they are all metals, hence, they are going to have valences of either 1, 2, or 3. There are also the noble metals which have effectively a valence of zero, like the noble gases in column 8. Hope this isn't too complicated.
