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.
When electrons are added to the outermost shell of a carbon atom it forms what?
negative ion
How many electrons does barium haven to give up to achieve?
Barium has two electrons in its outermost shell (the 6s subshell) and typically loses these two electrons to achieve a stable electron configuration, resembling that of the nearest noble gas, xenon. Therefore, barium needs to give up two electrons to achieve this stable state. As a result, it commonly forms a +2 oxidation state in compounds.
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.
An atom in which the outermost level is more than half tends to form is which ions?
An atom in which the outermost energy level is more than half full tends to fill its outermost energy level by adding one or more needed electrons. Such an atom forms a negative ion.

What happens when the outermost electron shell of an element such as neon contains the maximum number of eight electrons?
It forms complex compounds with related molecules

What part of an atom forms a chemical bond?
The electrons (especially the valence electrons)
What bond forms when one atom with many electrons in its outermost orbital takes an electron from another atom which has few electrons in its outermost orbital?
ionic bond
When electrons are added to the outermost shell of a carbon atom it forms what?
negative ion
How many electrons are in a phosphorus Ion's outermost energy level?
A phosphorus ion (P3-) has 8 electrons in its outermost energy level. This is because phosphorus has 5 electrons in its outermost shell, and when it gains 3 electrons to become an ion, it will have 8 electrons in total in its outermost energy level.
When an ionic bond forms which parts of the atoms are directly involved?
In an ionic bond, the valence electrons of one atom are transferred to another atom, creating positively charged ions (cations) and negatively charged ions (anions). The outermost electrons of the atoms are directly involved in the bond formation.
What is the ion of magnesium?
Magnesium forms a 2+ ion by giving away its two outermost electrons.
Which bond forms by sharing electrons in the outermost shell?
The sharing of electrons between atoms forms a covalent bond. If electrons are donated from one atom to another to form a bond this would be an ionic bond.
How many electrons does hydrogen have on outermost shell?
One. In nature, however, hydrogen forms a diatomic bond making it found as H2.
Does a noble gas form when electrons transfer from one atom to another and a bond forms?
No. Noble gases exist in nature, and are chemical elements. These are the six noble gases: Helium (He) Neon (Ne) Argon (Ar) Krypton (Kr) Xenon (Xe) and the radioactive Radon (Rn)
