Why dont noble gases become positive or negative?
They can , but its extremely rare and most often done in the Lab. Their outer most electron orbital, or valence shell, is full of all the electrons it wants to have (8), with 8 electrons in the valence shell, it is full essentially. The answer is WAY more involved than that, but thats the lowdown.
What types of atoms form positive ions?
atoms that belong to a metal element....because metals always loose electrons and gain a positive charge..!
What will be the charge on a aluminum ion?
Because Aluminium has valence shell electronic configuration of 3s2 3p1 This indicates it has 3 valence electrons and so, it has to loose 3 electrons to gain stability, . Aluminum has 13 protons(+ve charge) and 13 electrons(-ve charge) and after poising 3 electrons it's net charge becomes 13 - 10 that is + 3 .
How many electrons does a positive ion have?
they dont do nothing. Doing a hw on it now they dont do nothing... do you know how to transfer ions to electrons or the other way round
What allows valence elections in metals to move throughout the metal?
metal atoms being so close to one another that their outermost level overlap. Cause of the overlapping metallic bonds extend throughout the metal in all direction, so valence electrons can move throughout the metal.
How many electrons does phosphrous have to gain or loose to have 8 valence?
P has 5 valence electrons so it can gain 3 electrons or lose 5 electrons to have a full valence shell.
What are the electrons in the outer shell?
Those electrons are the valence electrons. They are the electrons which mostly take part in exchange of electrons or sharing of electrons. Hence, valence shell electrons are a very important part of chemistry since all the reactions due to them only.
What determines an element's reactivity?
The electrons determine the reactivity. How many valence electrons there are. It is easier to lose one electron rather than three, so an element with one valence electron will be more reactive than one with three.
What determines a dogs pitch?
it depends whether he gets paid enough and how loose his arm is
What is the rule?
atoms either loose or gain a maximum of 2 valence electrons like hydrogen
Would a magnesium atom prefer to lose or gain electrons?
Magnesium is in the second group (column) of the periodic table, so it has two valence electrons or electrons in its outer shell. so in order for it to fulfill the octet rule (get eight electrons in its valence shell most of the time), then it would rather lose two electrons and have a full valence shell than gain six electrons.
What is the valence?
the combining capacity of an atom is called valency
Why is it easy for a metal to loose an electron?
Metals useually have few valence electrons and they loose electrons from their outermost shell thus, forming an ion with positive charge (cations). This is because it is easy for metals to loose electron and attain stable or octet configuration similar to rare gases. Hence to attain stability metals lose valence electrons. E.g. sodium (At no. =11 ; electronic configu-1s2, 2s2, 2p6, 3s1) metal has one valence electron and it is easy for it to loose 1e rather to gain 7e to attain stable configuration. Hence it loose 1e forming Na+ cation.
Elements that have one valence electron tend to?
An element that has one valence electron tends to be more reactive, is able to form ions, and can become charged When an element has all eight valence electrons, they are more stable.
What group can gain or loose valence electrons?
I believe its silica based atom groups with covalent bonding. Just went over that stuff in geology :/
Why carbon atoms cannot form ionic bonds in its compounds?
carbon atoms cannot form ionic bonds because it can neither gain or loose electrons as it has 4 electrons in its valence shell.so it share its electrons which forms covalent bond.
How many electrons are in the valence shells of group 1?
There are 2 electrons in the first valence shell ("orbital"). The first orbital is an "s" orbital. If the atom is neutral in charge and there is only 1 electron - you have Hydrogen. If the atom is neutral in charge and you have only 2 electrons - you have Helium. Since the outermost shell of electrons is full, considerable chemical stability is conferred to the Helium atom, thus it is a member of the "Noble Gases" - those that have full comlpements of electrons in their outer shells, the others being Neon, Argon, Krypton, Xenon, and Radon.
