They achieve stable configuration by sharing their electrons in their outermost shell.
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.
Na2Cl would not be a stable compound because sodium typically loses one electron to achieve a stable electron configuration, while chlorine gains one electron for stability. In this case, sodium would need to lose two electrons to chlorine, which is energetically unfavorable. Thus, NaCl is the stable compound where sodium donates one electron to chlorine.
An ionic compound is formed when one atom donates an electron to another to achieve a stable electron configuration. For example, sodium (Na) will transfer an electron to chlorine (Cl) to form sodium chloride (NaCl), an ionic compound.
Four: All of its valence electrons. If a silicon atom loses four electrons, it has the stable electron configuration of neon, while if the atom gains four electrons it has the stable electron configuration of argon. A silicon atom can also form a stable compound, as contrasted with a stable electron configuration for a single atom, by sharing four electrons with one or more other atoms.
neon only because sodium loses an electron an its outer shell becomes empty making its configuration the same as neon and fluorine gains an electron making its configuration the same as neon as well.
No, lithium loses one electron to form a compound. It is an alkali metal with an electron configuration of 1s² 2s¹, so it tends to lose one electron to achieve a stable electron configuration.
Hydrogen wants to obtain one electron to achieve a stable electron configuration similar to the noble gas helium.
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.
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.
Sodium is an element which has one electron in its outer electron shell, and which can obtain a more stable electron configuration by getting rid of that electron. This causes it to undergo chemical reactions with other elements such as oxygen or chlorine, which need to acquire electrons in order to obtain a more stable electron configuration. If sodium reacts with water, it is reacting with the oxygen in the water molecule. In the case of sodium chloride, the sodium has already reacted with chlorine to form that compound, and has given up its outer electron, so it no longer needs to react with oxygen in water.
Na2Cl would not be a stable compound because sodium typically loses one electron to achieve a stable electron configuration, while chlorine gains one electron for stability. In this case, sodium would need to lose two electrons to chlorine, which is energetically unfavorable. Thus, NaCl is the stable compound where sodium donates one electron to chlorine.
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.
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
An ionic compound is formed when one atom donates an electron to another to achieve a stable electron configuration. For example, sodium (Na) will transfer an electron to chlorine (Cl) to form sodium chloride (NaCl), an ionic compound.
In a compound like BeCl2, chlorine typically exists as a chloride ion (Cl⁻) after gaining one electron. The electron configuration of a neutral chlorine atom is 1s² 2s² 2p⁶ 3s² 3p⁵. After gaining an electron, the configuration for the chloride ion becomes 1s² 2s² 2p⁶ 3s² 3p⁶, which is the same as that of argon, indicating that the chloride ion has a stable noble gas configuration.
Calcium loses two electrons to obtain a noble-gas electron configuration.
The group of elements that have a stable electron configuration are the noble gases.
