Non-metals for negative ions because they have the ability to gain electrons.
Only non-metals form negative ions - this ability (to gain electrons) is intrinsic to the nature of non-metals.
Only metals form positive ions - this ability (to lose electrons) is intrinsic to the nature of metals.
A positive ion (cation) is formed by removing electron(s) from an atom or group of atoms.
A negative ion (anion) is formed by gaining electron(s) an atom or group of atoms.
Nonmetals tend to form negative ions.
Nonmetals can form anions (negative ions).
Metals form positive ions. Nonmetals, however, for negative ions.
They gain electrons to become negative or an ion
nonmetals form negative ions (i.e. O^-2) by gaining valence electrons metals form positive ions (i.e. K^+1) by losing valence electrons
Nonmetals form ions by gaining electrons. When they gain more electrons, they usually produce negative ions, which is the opposite of metals.
It is possible to make positive ions of nonmetals e.g. oxygen, chlorine, by putting enough energy into them. They normally form negative ions when in a spontaneous reaction.
They gain the few electrons they need to form full octets
We haven't seen your graph. However, it is easy to say what kinds of ions elements form. Metals form positive ions and nonmetals form negative ions.
nonmetals form anions (negative ions). for a more thorough answer, they tend to form negative ions because they have high electron affinity (strong ability to attract electrons) and high ionization energy (very hard to take it's electron) and because metals have low electron affinity (attract electrons weakly) and low ionization energy (very easy to take it's electron), thus, the metal readily gives up it's electron and the nonmetals readily receive it to form negative ions.
Metals form positive ions and nonmetals form negative ions. A metal ion will form an ionic bond with a nonmetal ion, forming an ionic compound.
We know that nonmetals tend to form negative ions.The reason nonmetals tend to form negative ions is because chemical bonding is based on atoms' desire to attain or emulate the electron configuration of inert or noble gases. To do this they will loan out, borrow or share electrons. The nonmetals are a group of elements that have nearly full outer electron (valence) shells. Because they are "just a little short" of having a full shell, they want to borrow an electron or two very badly. And they will. If they snatch up an electron or two to bond, that will give them an overall negative electric charge. And that makes them negative ions.
Metal is an element that loses electrons easily to form positive ions; and nonmetals are elements that gain electrons easily to form negative ions.
Magnesium will form a positive ion during ionic bonding. Sulfur will form a negative ion during ionic bonding. In ionic bonding, metals form positive ions and nonmetals form negative ions.
Nonmetals tend to attract electrons to become negative ions.
Metals for positively charged ions and nonmetals form negatively charged ions.
You are only half right. Nonmetals do indeed gain electrons when they undergo chemical reactions, but this does not cause them to form positively charged ions. Remember that electrons have a negative charge! So if an atom gains electrons, it forms a negatively charged ion.
Nonmetals tend to gain electrons to form ions so as to obtain noble gas configuration.
they accept electrons lost by metals to become ions
Metals tend to form cations, or ions with a positive charge. Nonmetals tend to form anions, or ions with a negative charge. Remember that ions form to put the element in noble gas configuration with 8 valence electrons. Elements forming ions will take the most direct addition or subtraction of electrons to achieve this.
OF2 is covalent. Both elements O and F are nonmetals. They would both form negative ions which would not attract each other.
