It loses 2 electrons and becomes a +2 ion.
The electron configuration is responsible for this. If the elements have a stable electron configuration, they become inert.
Al3+,Al loses 3 electrons to attain stable electronic configuration therefore electron number is 10.
Not quite sure but i believe if it's stable or not.
an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
Metallic atoms acquire a stable noble gas configuration by losing electrons. Nonmetals usually attain such a configuration by gaining electrons.
The element Chlorine has 17 protons and 17 electrons in its stable form. The electron configuration is 2,8,7.
The electronic configuration of silver is [Kr]4d105s1. If it loses 1 electron then it will have completely filled d orbitals as its valence orbitals and is stable. It will never attain the electronic configuration of noble gas.
Neon has 8 valence electrons, which is a stable valence electron configuration.
Lithium is not completely stable.
Many stable ions have the configuration of a noble gas.
. Through the transfer of electrons between atoms
The noble gas configuration is known as the most stable configuration that an atom can achieve. In other words, the valence shell with ns2 np6 electron 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. 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.
Phosphorus must gain 3 electrons to achieve a stable electron configuration.
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
Krypton is a noble gas and need not lose electrons. It is already stable.
The electron configuration of the 4f energy sublevel is the most stable is 4f to the 14th power. The electron configuration of outer sublevels that are most stable is 4d up to the 5.5s up to the 1st power.
The standard model suggests an electron cofiguration for nickel (element number 28)as :[Ar] 4s2 3d8However, relativistic effects make the more stable configuration [Ar] 4s1 3d91s2,2s2,2p6,3s2,3p6,4s2,3d8
It is because Sodium has to lose one electron to gain the nearest octet configuration of Neon and Chlorine has to gain one electron to attain stable electronic configuration of the nearest inert gas which is Argon. Thus there is complete transference of an electron from Sodium to Chlorine and thus the ionic bonding If the first element is a metal it is ionic, that's why sodium chloride is ionic. It the first element is a nonmetal it is covalent.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
The electron configuration of 10Ne is [1s2.2s2. 2p6]; it is very stable, obeying the 'Octet'-rule (like all noble gases do).
They achieve stable configuration by sharing their electrons in their outermost shell.
The atomic number of potassium is 19. The outer shell of potassium contains one electron. It can attain a stable configuration by loosing this electron. This is the reason that potassium forms k+ ions. Similarly, calcium contains two electrons in its outer shell and attain stable configuration by loosing the 2 electrons. Thus, it forms Ca2+ ions.
actually valency is the combining capacity of atoms so to attain stable configuracy the lose or gain electrons for example chlorine has configuration of 2,8,1 so in order to attain stable configuracy they lose 1 electron.THIS is why we say chlorine has -1 as valency
