Oxygen atoms need to share or gain two electrons in order to achieve a stable electron configuration.
They achieve stable configuration by sharing their electrons in their outermost shell.
This is because in nitrogen the 2p subshells are filled by 3 electrons which is half filled electronic configuration. But oxygen has to lose an electron to attain the half filled electronic electronic configuration. Hence nitrogen is more stable than oxygen.
Sodium looses one electron to achieve noble gas electronic configuration.The formula of ion formed is Na+
They have to gain 1 electron. Halogens have 7 electrons in their valence shell and noble gasses have 8.
The electron configuration of copper is: [Ar]4s13d10. It isn't 4s23d9 because Cu is able to obtain a more stable electron configuration when it takes an electron from the 4s and adds it to 3d. A half filled 4s and a completely filled 3d is more stable.
They achieve stable configuration by sharing their electrons in their outermost shell.
A stable electron configuration.
Atoms are trying achieve a stable electronic configuration i.e., stable arrangement of electrons in their electron shells. All configurations are not stable. Mostly stable configuration is attained by forming an octet of electrons in outer most shell. Sometimes octet rule is violated also.
Only three electrons.
. Through the transfer of electrons between atoms
Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration. Although the formation of an octet is the most stable electron configuration, other electron configurations provide stability. These relatively stable electron arrangements are referred to a pseudo-noble gas configuration.
When two oxygen atoms merge, they form a covalent bond. In a covalent bond, the atoms share electrons to complete their outer electron shells. This allows both atoms to achieve a more stable electron configuration.
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
The group of elements that have a stable electron configuration are the noble gases.
This is because in nitrogen the 2p subshells are filled by 3 electrons which is half filled electronic configuration. But oxygen has to lose an electron to attain the half filled electronic electronic configuration. Hence nitrogen is more stable than oxygen.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
Br typically gains one electron to achieve a stable electron configuration, rather than losing electrons.
