Group 1A: The Alkali Metals: H, Li, Na, and K

Group 2A: The Alkali Earth Metals: Be, Mg, and Ca

Group 3A: The Boron Family: For the most part, only Al

These atoms all want to get rid of their 'remainder' electrons so they have a full outer shell; like the Noble Gases.

Group 1A only has to loose 1 electron to be in its 'happy' state. (+1 charge)

Group 2A has to loose 2 electrons (+2 charge)

Group 3A has 3 to loose. (+3 charge)

Since a regular atom is naturally neutral (equal number of electrons to protons), loosing electrons (which are negative) off set the atom's 'balance of charge' and make it positive. At this point, the atom is no longer an atom, but an ion.

When Group 2A elements form ions they do what?

When Group 2A elements form ions they lose the electrons in their outer shell. In doing so they form positive ions known as cations.


What types of ions do different elements form?

Ions are cations (positive) or anions (negative).


Why do some atoms form positive ions and others form negatiove ions?

some elements like sodium have low electronegativity and elements like chlorine have high electronegativity. So when they react sodium lose electrons and form positive ions and chlorine gains electrons and form negative ions. This is the reason why some atoms make positive ions and some negative ions.


Do elements react to form negative ions in metals?

Metals forms positive ions, cations.


Does lithium form positive ions?

Yes, Lithium forms positive ions. Since Lithium is in the first group of the periodic table of elements, it will form Li+ ions (lithium ions), which a charge of 1+.


Why do group 1 elements form positive ions?

because they have one electron in their outermost shell which can be easily removed and this removing electron form positive ions.

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.


How are elements that form positive ions grouped in the periodic table relative to the elements that form negatives ions?

The lower the the Atomic Number, the higher the Ionic Energy.


What is Elements that easily lose electrons to form positive ions?

What groups form negative ions on the periodic table?

The non-metal group forms negative ions therefore the metals form positive ions.


On the periodic table which groups of elements tend to form negative ions?

On the periodic table, Groups 4 - 7 tend to form negative ions. These groups tend to gain electrons, thus forming negative ions.
