What is the formula of the ions formed when sulphur gain or lose valence electrons and attain a noble gas configuration?
When sulfur gains electrons, it forms the sulfide ion with a 2- charge, represented as S2-. When sulfur loses electrons, it forms the sulfide ion with a 2+ charge, represented as S2+.
What element has 10 electrons when it form an anion with a 2 negative charge.?
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.
Which group contains eight valence electrons?
Group 18 contains eight valence electrons, namely the noble gases.
How many electrons must be gained or lost by each element to achieve a noble gas configuration of electrons for oxygen?
Oxygen needs to gain 2 electrons to achieve a noble gas configuration, as it has 6 valence electrons and wants a full valence shell of 8 electrons, like a noble gas.
How many valence electrons do argon has?
Argon is a noble gas. All noble gasses have 8 valence electrons. Thus argon has 8 valence electrons as well.
How can elements achieve the configuration of noble gases?
By transfer or sharing of electrons.
Why are the noble gases not likely to form compounds?
The noble gases already have their full set of valence electrons. They don't need to share or transfer any of their electrons with other molecules.
Noble gases have a set of eight outermost electrons which forms what?
Noble gases have a set of eight outermost electrons, which forms a stable electron configuration known as an octet. This full outer shell makes noble gases highly stable and unreactive under normal conditions.
What is another word for noble gases?
Another word for a noble gas is an inert gas. These elements have the maximum electrons in their highest energy level.
Do noble gases have the maximum number of electrons in their outer energy level?
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
Which element will have a noble gas configuration if it forms an ionic bond by accepting two electrons from a magnesium atom?
The element that will have a noble gas configuration by accepting two electrons from a magnesium atom is oxygen. By gaining two electrons, oxygen will achieve a stable octet configuration similar to that of a noble gas, fulfilling the octet rule.
What are the characteristic forms of Octet Rule?
Covalent bonding: Atoms share electrons to achieve a full outer shell (8 electrons for most atoms). Ionic bonding: Atoms transfer electrons to achieve a full outer shell. Metallic bonding: Electrons are delocalized and move freely between atoms in a metal lattice, allowing for electrical conductivity. Noble gas configuration: Atoms attain stable electron configurations like noble gases by either gaining, losing, or sharing electrons.
Will tellurium lose or gain electrons?
Tellurium tends to gain electrons in chemical reactions to achieve a full outer shell and attain the stable electron configuration of a noble gas. It typically forms -2 oxidation state by gaining two electrons.
How many electrons are present in the valence level for all noble gases except helium?
There are 8 electrons present in the valence level for all noble gases except helium. This is because in the outermost shell, known as the valence shell, noble gases (excluding helium) have a full octet of electrons, making them stable and unreactive.
Noble gas contain electrons?
All noble gasses contain electrons. In fact, all gasses contain electrons.
Why does boron have a positive ion?
Boron gains noble gas configuration by losing 3 electrons. So it forms positive ions.
What element is a noble gas and has 36 electrons?
Krypton is a noble gas with 36 electrons.
