Why lithium and other group 1 elements usually form positive ions while fluorine and other group 17 elements form negative ions?

Because group 1 has 1 electron in it's outer most shell and the have to fill the energy level, so they gave there electron and form positive ion (cation).
And group 17 has 7 electrons in it's outer most shell and they need to complete their shell so the gain electron and form negative ion (anion).

Which of the following elements belong in halogen family fluorine neon lithium bismuth?
Only Fluorine belongs in the halogen family.
Which element forms an ion with a charge of negative one?
The elements in Group 1A all form ion with one positive charge. This group is collectively knows as the Alkali metals. They are Lithium, Sodium, Potassium, Rubidium, Caesium, and Francium. Hydrogen ions also can have a positive one charge, but it may, as easily, have a negative one charge.
Is lithium and fluorine ionic or covalent?
Lithium oxide is an ionic compound, further, all oxides of the group 1 elements are ionic.
Name the compounds that are formed from lithium and fluorine?
When lithium and fluorine react, they form an ionic compound - lithium fluoride (LiF).
What is common to the following elements lithium carbon oxygen and fluorine?
Lithium, carbon, oxygen, and fluorine are all reactive elements, which means that they want to bond with other elements to form compounds. Carbon and oxygen together can even covalently bond together to form the compound CO2 (carbon dioxide). Lithium and fluorine can ionically bond because lithium needs to lose its single valence electron to take away its unnecessary second energy shell to finish with a single full energy shell, while fluorine needs to gain one more valence electron to make its last energy shell full, forming the compound LiF (lithium fluoride).
Is lithium negative or positive?
Lithium is a neutral metal that can form positive ions.
What are 2 elements most reactive on periodic table?
Lithium and Fluorine.
What elements belongs on the halogen family flurine neon lithium bismuth?
Fluorine.
Which of these are in the halogen family fluorine neon lithium or bismuth?
Fluorine The Halogen Family of elements is made up of the elements Fluorine, Chlorine, Bromine, Iodine and Astatine. Neon is one of the Inert or Noble gases. Lithium is a member of the Alkali Metal group of elements. Bismuth is in the same group of elements as Nitrogen, Phosphorus, Arsenic and Tin.neon
Which of the following elements belong in halogen family fluorine neon lithium bismuth?
Only Fluorine belongs in the halogen family.
Two highly reactive elements in period 2 are the metal lithium and what?
Nonmetal fluorine
When lithium loses an atom does it become a negative or positive ion?
Lithium has 3 protons and 3 electrons.
List eight elements from period 2?
these elements are lithium, berylium, boron, carbon, nitrogen, oxygen, fluorine and neon.
What are the period 2 elements?
Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, and Neon.
Which wire is positive or negative in hot power lithium polymer battery?
Red is positive, Black is the negative
Why is lithium the most reactant element?
I believe that Fluorine is the most reactive of the elements. Lithium may be the most reactive metal, but don't forget potassium.
