What group of elements tends to form plus 2 charge?
The Group 2 elements, or the Alkali Earth metals, tend to form +2 charges when they become ions. This is because Group 2 metals have 2 valence electrons and it is easier to lose 2 electrons than it is to gain 6 electrons to form a full outer shell.
What group of elements tends to form plus 1 charge?
The Alkaline metals (Group 1 metals). This is because they all have one valence electron and to become more stable by completing their outer shells, it is easier to lose 1 electron than it is to gain 7.
Which tends to form anions when bonding with other elements?
Anions are negative ions, so any element that gains a negative charge in a chemical reaction. Some examples of elements that commonly do this are the halogens (flourine, chlorine, bromine, iodine, astatine) and oxygen.
Does fluorine form an ion with a positive charge?
NO !!!! Fluorine form an ANION , that is an ion eith negative charge. 'F^(-) '.
Which group in the periodic table tends to form ions with a 2 charge?
An element should release two of its outermost electrons to obtain +2 ion. The elements in group 2A are the most likely elements to have this configuration. These are known as Alkali Earth Metals.The elements in the 2nd group have 2 valence electrons. Elements give away their valence electrons to get stable electron configuration. The elements in the 2nd group such as beryllium, magnesium, calcium, strontium, barium likely to have positive ion with charge of 2.Group II elements (the alkaline earth metals). This is because this particular group of elements have two extra electrons in their electronic configurations. They need to lose these two electrons to attain the stable noble gas configuration. So they will have a tendency to lose them to other atoms or group of atoms, in the process incurring a double positive charge (since there will now be two less electrons than protons). So Be, Mg and Ca will all form positive ions (cations) with a charge of +2. They are represented by Be2+, Mg2+ and Ca2+ respectively. But, other elements like copper and barium will also form cations of charge +2.
What subatomic particle has a very small mass and a negative charge?
Electrons have a negative charge. When an element had more electrons than protons, it tends to have a negative charge.
Which group of elements on the periodic table tends to form ions?
Group one, not including element 1 (helium) tend to form ions.

Why are salts conductors of electricity?
I am not sure whether pure salts conduct electricity well. However, a salt in solution tends to split into positive and negative ions - so you have lots of charge carriers in that case.I am not sure whether pure salts conduct electricity well.

What causes the water molecule to have a negative charge?
The water molecule does not have a negative charge. The oxygen end of the molecule has a partial negative charge and the hydrogen end has a partial positive charge. This is because the oxygen atom is more electronegative than the hydrogen atoms, and tends to hold the shared electrons more tightly than the hydrogen atoms.
What are water's bad qualities?
Water has several properties that make it a very unique substance. ... the water molecule tends to have a positive charge while the other has a negative charge.

Why do elements in the same group react in the same ways?
It usually reacts the same?Alkali metals all react with water to give a alkali metal hydroxide and hydrogen.I thought you wrote "How do elements in the same group (in the periodic table) usually react?"EDIT: Hmm.... family. Opps I read wrong again.All alkanes contain Carbon-Carbon single bonds.All alkanes combust to give either carbon dioxide and water or carbon monoxide and waterAll alkenes contains Carbon=Carbon double bondAll alkenes decolourises aqueous bromineAll alcohol oxidises to give a carboxylic acid.Lol, that's too many examples....So, yea.... they usually reacts the same too.........
Is oxygen negative in charge?
That depends on whom you pair it up with. In most connections, it tends to be the more negatively charged partner. In a water molecule, oxygen is paired with Hydrogen atoms; oxygen being more electronegative than hydrogen, oxygen is negative in this molecule. In molecules where oxygen is connected e.g. with F, it is F that is the more electronegative partner, and oxygen is the positive partner. In general, elements that are further up and right in the periodic table of elements tend to have higher electronegativity than elements further down and left.
