What is the correct electron configuration for Cu?
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.
Why would you never expect to find Na2Cl as a stable compound?
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.
Which pair of atoms will form an ionic compound?
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.
How many valence electrons are transferred from the nitrogen atom to potassium in the formation of the compound?
In the formation of the compound, potassium will transfer one electron to nitrogen to achieve a stable electron configuration. Nitrogen needs three additional electrons to reach a stable configuration, so it will receive one electron from potassium, and vice versa, making a total of 2 electrons transferred.
How many electrons does silicon need to gain or lose to have a stable electron configuration?
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.
Will lithium gain one electron when it reacts to form a compound?
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.
How many electrons does hydrogen want to obtain?
Hydrogen wants to obtain one electron to achieve a stable electron configuration similar to the noble gas helium.
What is the formula of the ion formed when sodium achieves a stable electron configuration?
Na+ is the formula of the ion formed when sodium achieves a stable electron configuration.

What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
What symbol would represent a chlorine ion that has ionized to have a stable electron configuration?
What is a pseudo-noble gas?
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.

Why does metallic sodium react violently with water while sodium chloride does not?
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.
Which pair of atoms will form an ionic compound?
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.
How many valence electron does Ca lose or gain to attain noble-gas electron configuration?
Calcium loses two electrons to obtain a noble-gas electron configuration.
What group of elements have stable electron confoguration?
The group of elements that have a stable electron configuration are the noble gases.
