How many electrons must be gained or lost for Mg to attain a noble-gas?
Magnesium (Mg) has 12 electrons. To attain a noble gas configuration, Mg would need to lose 2 electrons to have the same electron configuration as a noble gas (like neon). This would result in Mg forming a +2 ion.
What is the charge of a sulfide ion that is isoelectric with its nearest noble gas?
The charge of a sulfide ion that is isoelectric with its nearest noble gas (argon) is -2. This means that the sulfide ion has gained two electrons in order to have the same electron configuration as the noble gas.
How many electrons must be gained or lost for Mg to attain a noble gas?
It should loose 2 electrons to become a noble gas.
Which noble gas has the same electron configuration as magnesium 2 plus?
The noble gas that has the same electron configuration as magnesium ion (Mg²⁺) is neon (Ne). When magnesium loses two electrons to form Mg²⁺, it has the electron configuration of 1s² 2s² 2p⁶, which is identical to that of neon. Thus, both Mg²⁺ and Ne have a complete octet in their outer shell.
What is the formula of the ion formed when sulfur achieves a noble gas electron configuration?
Sulfur atoms will gain two electrons in order to achieve a noble gas electron configuration. A sulfide ion has the formula S2-.
Which ion forms when magnesium donates 2 electrons?
When magnesium donates 2 electrons, it forms a magnesium ion with a +2 charge, represented as Mg²⁺. This occurs because magnesium has two valence electrons in its outer shell, and by losing these electrons, it achieves a stable electron configuration similar to that of the nearest noble gas, neon. The Mg²⁺ ion is commonly found in various compounds, including magnesium oxide and magnesium chloride.
What is the noble gas electron configuration of Ca2 plus?
calcium is normally [Ar] 4s2 if it is a 2+ ion, then it has lost 2 electrons so the configuration is just [Ar]
How many electrons must be lost given the following atoms Ca Mg Ba Be to attain Noble gas?
All should lose 2 electrons to attain the nearest noble gas configuration
What is the symbol for magnesium ion?
The symbol for a magnesium ion is Mg^2+. The superscript 2+ indicates that the magnesium ion has a positive charge of 2.
What is the formula of the ion formed when cadmium achieves a pseudo noble gas electron configuration?
The pseudo noble gas electron configuration for cadmium is [Kr] 4d^10 5s^2. Cadmium forms a 2+ cation to achieve a pseudo noble gas electron configuration, where it loses its two 5s electrons and has the electron configuration of [Kr] 4d^10.
What describes what happens when an atom becomes an ion with a 2-charge?
An ion with a charge of 2- was an atom that lost 2 electrons to gain noble gas configuration.
What is the noble gas configuration of iron-II ion?
The noble gas electronic configuration of iron is [Ar] 3d6 4s2
