The phosphide ion has 18 electrons as it forms an anion with the valency of three.
An oxygen anion with a charge of -2 has 10 electrons. Oxygen normally has 8 electrons, but an anion with a -2 charge gains two additional electrons.
An oxygen anion has 10 electrons, because it gains two electrons to achieve a full valence shell of 8 electrons.
A bromine anion has 8 valence electrons. This is because bromine, with 7 valence electrons, gains one extra electron when it forms an anion to achieve a full octet and become stable.
No, having four valence electrons does not determine whether an atom is an anion. An anion is formed when an atom gains electrons to have a negative charge. If the atom with four valence electrons gains four more electrons, it would become an anion.
The anion of OCl (hypochlorite ion) has 8 valence electrons. This is because oxygen contributes 6 valence electrons and chlorine contributes 7 valence electrons. The overall negative charge of the anion adds one more electron, totaling 8 valence electrons.
Chloride anion has 8 valence electrons.
An oxygen anion with a charge of -2 has 10 electrons. Oxygen normally has 8 electrons, but an anion with a -2 charge gains two additional electrons.
An oxygen anion has 10 electrons, because it gains two electrons to achieve a full valence shell of 8 electrons.
The number of electrons is 18.
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.
A bromine anion has 8 valence electrons. This is because bromine, with 7 valence electrons, gains one extra electron when it forms an anion to achieve a full octet and become stable.
A chlorine anion has gained one electron, resulting in a total of 18 electrons. A neutral chlorine atom has 17 electrons, but gaining one electron makes it negatively charged, with a total of 18 electrons in the anion.
No, having four valence electrons does not determine whether an atom is an anion. An anion is formed when an atom gains electrons to have a negative charge. If the atom with four valence electrons gains four more electrons, it would become an anion.
The anion of OCl (hypochlorite ion) has 8 valence electrons. This is because oxygen contributes 6 valence electrons and chlorine contributes 7 valence electrons. The overall negative charge of the anion adds one more electron, totaling 8 valence electrons.
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.
16 (from its own) + 2 (from the charged ion) = 18 electrons
Phosphorus (P) has 15 electrons.
