An atom with extra (a higher number than that of its protons) electrons is an anion. An atom with a lower count than its protons is a cation. They are often reffered to as positive (cation) or negative (anion) Ions. An Ion is defined as a charged particle.
Ion. If the atom becomes more positive after the transfer of electrons, it is a cation. The metals in groups 1 and 2 are more likely to be cations. If the atom becomes more negative after the transfer of electrons, it is an anion. The halogens in group 6 and 7 are more likely to be anions.
Iodine gains electrons to form an anion (I-) through the process of reduction, as it has the ability to accept an electron to achieve a stable electron configuration.
low ionization energy
When a metal reacts with a nonmetal, the metal typically loses electrons to the nonmetal. This transfer of electrons creates ions with opposite charges, with the metal forming a positive ion (cation) and the nonmetal forming a negative ion (anion).
Nitrogen will gain three electrons to form a nitride anion with a charge of -3.
A bromine anion (Br-) contains 8 valence electrons. Bromine is in group 7A of the periodic table and has 7 valence electrons. When it gains an extra electron to form an anion, it now has a total of 8 valence electrons.
Anion.
"Carbonate" is not an element or an element group; instead, it is a polyatomic anion and is one of a large group of oxyanions.
There is no halogen that will become anionic. All of the valence electrons in halogens are filled, thus halogens will not react with any other compound or element. Bromine is an element that will form and anion with 36 electrons.
A single element cation and single element anion form a binary ionic compound, where one element is a metal and the other is a nonmetal. The metal forms the cation by losing electrons, while the nonmetal forms the anion by gaining electrons. Examples include NaCl (sodium chloride) and KBr (potassium bromide).
The element with 10 electrons in its neutral state is neon (atomic number 10). When it forms an anion with a 2- charge, it gains 2 electrons to have a total of 12 electrons, taking on the electron configuration of the noble gas, argon.
A -2 anion indicates that the ion has gained two extra electrons. Since there are 8 protons in the nucleus (8 electrons in a neutral atom), adding two extra electrons would give a total of 10 electrons in the anion.
No, an anion does not always form a covalent bond. An anion can form both ionic and covalent bonds depending on the nature of the element it is bonding with. In an ionic bond, an anion will typically form a bond with a cation through the transfer of electrons, while in a covalent bond, an anion will share electrons with another element.
This object is negatively charged and it is called an anion.
are you in Chem 115 at WVU? i have the same question for hw
There are 7 electrons in the outer shell of a chlorine atom. Chlorine belongs to Group 17 of the periodic table, so it has 7 valence electrons.
