How many valence electrons do the anions have when they bond?
This number is different for each anion.
What group in the periodic table forms anions?
The elements in group-15 , 16 and 17 have 5,6 ad 7 valence electrons respectively , so they gain electrons to form anions.
What are formed by a loss or gain of valence electrons during a chemical combination of elements?
Cations are formed by the loss of electrons, anions are formed by the gain of electrons. The force of attraction between cations and anions results in ionic bond.
What are positive and negative ions called?
Positive ions are called cations, and negative ions are called anions. Cations have a net positive charge because they have lost electrons, while anions have a net negative charge because they have gained electrons.
The outermost electrons in an atom are called?
Valence electrons

How can you tell from an element's number of valence elns whether the element is more likely to form a caor an anion?
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.

How may valence electrons atoms of can nonmetals have?
Variable; a correct answer is possible only for a specified nonmetal.
How many valence electrons does an ionic bond have?
Ionic bonds do not have valence electrons; rather, they form between atoms by electron transfer where one atom gives up electrons (cations) and the other gains electrons (anions). The resulting ions are held together by electrostatic forces, not by sharing electrons as in covalent bonds.
How are the anions in all types of binary compounds similar?
Anions in binary compounds are negatively charged ions that have gained electrons to achieve a stable electron configuration. In all types of binary compounds, anions are typically nonmetals that form anions by gaining electrons to fill their valence shell. These anions are named with an -ide suffix when combined with a cation.
What is another name for outermost electrons?
Electrons in the outermost shell are valence electrons!
The outermost electrons in an atom are called?
Valence electrons
Why are anions larger?
Anions have supplementary electrons.
What are the electrons in the outmost shell of an atom called?
the electrons in the outermost shell of an atom are considered to be the valence electrons.
