Why do atoms form positive ions and others form negative ions?
It is a matter of how full an atom's outer or valence shell of electrons is. For most atoms, the most stable setup is one with a full shell of 8 valence electrons, and an atom will gain or lose electrons to achieve this. For atoms with close to 8 valence electrons, such a chlorine (7 valence electrons, it is generally easier to gain electrons and thus become negatively charged. For atoms with few valence electrons, such as sodium (1 valence electron), it is easier to lose electrons and go down to the next lowest shell, which is already full.
What are atoms valence electrons?
the electrons on their outer shell, all atoms want to gain a full valence shell.
How with 5 valence electrons will achieve a full set of valence electrons?
If you're asking how will an atom with 5 valence electrons will achieve a full set of valence electrons, then the answer would be that they bond with other atoms to gain a full set of the valence electrons by sharing or gaining 3 electrons.
How with 4 valence electron will achieve a full set of valence electron?
An atom with 4 valence electrons will have to either gain 4 electrons or lose 4 electrons to achieve a full set of eight electrons.
What do atoms desire to be?
Atoms desire to have their valence electrons full to the maximum capacity.
Will chlorine gain an electron?
Chlorine atoms have 7 outermost electrons and need to gain an electron to achieve the stability of a full valence shell.
What states that atoms tend to gain lose or share electrons in order to achieve a full set of valence electrons typically?
The octet rule.
How can an atom that has 5 valence electrons achieve a full set of valence electrons?
Either lose 5 electrons, which is least likely, or gain 3 electrons.
How many valence electrons are needed to achieve a full outer shell?
It depends, most atoms need 8 total valence electrons in their outer shell (some need 2). So subtract the number they have (determined by the group that the element is in) from 8 and that is how many they need to fill their outer shell!
Which elements is less reactive an element whose atoms have seven valence electrons or an element whose atoms have eight valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
How many valence electron does neon atoms have?
Neon is in group 8 of the periodic table, so it has 8 valence electrons.
A full valence shell of electrons means that the atom is unstable and likely to combine with other atoms?
No: A full valence shell means the atom is very stable and has little likelihood of combining with other atoms.
