They have one valence electron. If this electron is lost, the atoms form cations with the electronic configuration of the nearest noble gas.
Atoms gain, lose or share electrons and try to attain noble gas configuration.
Chemical properties depend on electron configuration. By either gaining or losing electrons, an atom changes its electron configuration and therefore its chemical properties also change.The atoms of an element will react to achieve a noble-gas configuration. The atoms will either gain or lose electrons to achieve such a configuration.
Hydrogen gas has the noble gas electron configuration with a single covalent bond; it only requires two electrons for this (you've probably heard the "duet rule"). Otherwise, in the right conditions, you can maybe combine two atoms in the 4A group (Carbon, Silicon, Germanium, Tin, Lead, etc.), or an atom in the 3A plus an atom in the 5A group. All other combinations would be considered ionic bonds.
Atoms attain stable configuration of noble gas by gaining or losing electrons to achieve a full outer electron shell, often referred to as an octet. This stable arrangement mimics the electron configuration of noble gases and provides the atom with increased stability and lower energy. This can be achieved through ionization (loss or gain of electrons) or bonding with other atoms to share electrons.
No, Ni2+ does not have a noble gas configuration. A noble gas configuration is attained when an atom has a full valence shell of electrons, like the noble gases in Group 18 of the periodic table. Ni2+ has lost electrons to achieve a stable electron configuration but does not have a full valence shell like a noble gas.
Atoms gain, lose or share electrons and try to attain noble gas configuration.
Atoms lose or gain or share electrons and tend to attain noble gas configuration
Chemical properties depend on electron configuration. By either gaining or losing electrons, an atom changes its electron configuration and therefore its chemical properties also change.The atoms of an element will react to achieve a noble-gas configuration. The atoms will either gain or lose electrons to achieve such a configuration.
By acquiring noble gas configuration elements become stable .
Atoms try to imitate the noble gases in the periodic table by changing their electrons. Noble gases have stable electron configurations, so other atoms will gain, lose, or share electrons in order to achieve a similar stable configuration like the noble gases.
The column in the periodic table that contains atoms with an ideal electron configuration is the noble gases group (Group 18). These atoms have a full outer shell of electrons, making them stable and less likely to react with other elements.
Only group 18 elements have noble gas configuration. All other elements lack a noble gas electronic configuration.
They can form ionic compounds with halogens.
They should gain 2 electrons to attain noble gas electronic configuration. (it doesn't become a noble gas as the number of protons are not same)
