element has six valence electrons. Which ionic charge will its ion carry? (1 point)
О 6+
O 2+
O 6-
О 2-
The element with six valence electrons will have an ion carrying a charge of 2-.
The element that has six valence electrons will carry an ionic charge of 2-.
To determine the ionic charge of an element, you need to look at its valence electrons.
Valence electrons are the electrons in the outermost energy level or shell of an atom. They are responsible for the element's chemical properties, including how it forms bonds with other atoms.
In this case, the element has six valence electrons. To find the ionic charge, you can use the octet rule, which states that atoms tend to gain, lose, or share electrons in order to achieve a full outer shell with eight electrons.
Since this element has six valence electrons and it wants to achieve a full outer shell with eight electrons (following the octet rule), it will tend to gain or lose two electrons.
If the element gains two electrons, it will have a net negative charge of 2-, since adding two negative electrons outweighs the positive charge of the protons. Hence, the correct answer is "O 2-."
