What else can I help you with?
What do you call the electrons located in an atom-ions outer most energy level?
Valence electrons.
How do you find the charge of an atom with 7 valence electrons?
The halogens, group 17, have 7 valence electrons. When they form ions, they gain 1 more valence electron and become ions with a charge of 1-.
What is same about the positive ions and negative ions?
They both are ions and both have shared valence electrons
Why do atoms change to ions?
Because they either lose or gain valence electrons.
Do metals contain fewer valence electrons?
No, metals typically have fewer valence electrons compared to nonmetals. Valence electrons are the outermost electrons in an atom, involved in bonding and determining the reactivity of an element. Metals tend to have fewer valence electrons which allows them to easily lose electrons and form positive ions.

Valence electrons.
Negative ions form when atoms-blank-valence electrons?
Negative ions form when atoms GAIN valence electrons.

What are Al atoms called after they give up their valence electrons?
Aluminum atoms are called ions, specifically aluminum ions. By losing their valence electrons, aluminum atoms become positively charged ions, as they have more protons than electrons.
What is the relationship between groups valance electrons and ionic charge?
The number of valence electrons in an atom determines its ability to form ions. Atoms that have few valence electrons tend to lose them to form positive ions, while atoms with many valence electrons tend to gain electrons to form negative ions. The ionic charge of an ion is related to the number of electrons gained or lost during the formation of the ion.
What is meant valence electron?
A valence electron are electrons on the outer most shell/oritals of an atom. Basicly they are the electrons on the outside of an atom. Valence electrons are very important when involving chemical bonds and ions.
Why do atoms change to ions?
Because they either lose or gain valence electrons.
Why do atoms form positive ions and others form negative ions?
It is a matter of how full an atom's outer or valence shell of electrons is. For most atoms, the most stable setup is one with a full shell of 8 valence electrons, and an atom will gain or lose electrons to achieve this. For atoms with close to 8 valence electrons, such a chlorine (7 valence electrons, it is generally easier to gain electrons and thus become negatively charged. For atoms with few valence electrons, such as sodium (1 valence electron), it is easier to lose electrons and go down to the next lowest shell, which is already full.
Do metals contain fewer valence electrons?
No, metals typically have fewer valence electrons compared to nonmetals. Valence electrons are the outermost electrons in an atom, involved in bonding and determining the reactivity of an element. Metals tend to have fewer valence electrons which allows them to easily lose electrons and form positive ions.
What is the pattern of the ions in an ion compound?
The elements in a same group tends to form ions with the same charge. It is most consistent at each end of the periodic table.
Do ions of the same element have the same number of valence electrons?
Atoms of the same element do, but some ions do not. Iron forms 2+ and 3+ ions
