Same as a metal. It need to gain/lose electrons intill it has a full outer shell.

What does a nonmetal need to do to form an anion?
A non metal must gain from 2 to 3 electrons to form an anion.
Why is the reactivity series important when extracting metals from ores?
By knowing the reactivity series of elements, we can tell which elements will displace each other. So to extract a metal from an ore, you need to use an element higher up in the reactivity series, so that the metal will be replaced by the other element, and you are left with a more pure form of the metal.
What type of bond will strontium and sulfur form?
Strontium is an earth metal (element #38), and iodine is a halide non-metal (element #53), therefore they would form an ionic bond. Strontium ions have a +2 charge, and iodines -1, so to form a neutral-charged compound, we need 2 iodines for every Strontium, and the chemical formula would be: SrI2.
How many electrons do you need to become a noble gas?
A species (element, cation or anion) should have eight valence electrons to have a noble gas electronic configuration. However element upto atomic number 4 may have 2 valence electrons and attain the electronic configuration of helium noble gas.
Can calcium and oxygen form an ionic bond?
because calcium is a group 2 element which makes it a metal an oxygen is a group 6 element which makes it a a nonmetal. calcium have to lose 2 electrons to become iso-electronic to neon (to become stable) and oxygen need two electron's to become iso-electronic to neon as well (to become stable) calcium transfer its 2 electrons to oxygen its will become stable and so will oxygen. because this type of bonding took place between a metal an a nonmetal its refers to as a ionic bonding and the compound which form as a result of this type of bonding is known as a ionic compound
What does a nonmetal need to do to form an anion?
A non metal must gain from 2 to 3 electrons to form an anion.
What does a nonmetal elements need to do to form an anion?
A non metal must gain one or two electrons to form an anion
Is sulfide an element or a compound?
A sufide is an anion form of the element sulfur. It can form compounds if it combines with other elements. Sulfide on it's own is not a compound, you need a prefix to that like Hydrogen Sulphide. Do not get this mixed up with a sulfate; you can get copper sulphate but not copper sulfide.
What 2 element types form an ionic compound?
A metal (as positively charged cations) and a non-metal (as negatively charged anions) need to be held together to form an ionic compound.
What element do you need to make metal on little alchemy?
fire plus stone equals metal
Why is the reactivity series important when extracting metals from ores?
By knowing the reactivity series of elements, we can tell which elements will displace each other. So to extract a metal from an ore, you need to use an element higher up in the reactivity series, so that the metal will be replaced by the other element, and you are left with a more pure form of the metal.
How many electrons must neon loose to form a anion?
Do note that elements form anions to gain stability (duplet and octet rules). Neon is a noble gas. It is inert, as its valence shell is full (and follows the octet rule). It does not need to form an anion, as it is already stable.
Why is nitrogen in the non metal group?
The electronic configuration of nitrogen is 1s2 2s2 2p3. It is considered a non-metal because there is a lack of electrons (in its 2p shell) and needs to gain electrons to form the stable noble gas structure, thereby becoming an anion. On the other hand, metals have "excess" electrons and will need to lose them and form a positively charged cation to attain the noble gas structure.
What type of bond will strontium and sulfur form?
Strontium is an earth metal (element #38), and iodine is a halide non-metal (element #53), therefore they would form an ionic bond. Strontium ions have a +2 charge, and iodines -1, so to form a neutral-charged compound, we need 2 iodines for every Strontium, and the chemical formula would be: SrI2.
What do you need to find out the mass number of nitrogen?
Nitrogen is a non metal element. Mass number of it is 14.
What does a nonmetal atom need to do to form an ion?
A non metal needs to GAIN electrons to form an ion
What does a metal atom need to do in oreder to form a cation?
lose 1 or more electrons
