What is associated with more energy a 2s or a 3s orbital?
A 3s orbital is associated with more energy than a 2s orbital. This is because the principal quantum number (n) is higher for the 3s orbital compared to the 2s orbital, resulting in higher energy levels.
Evaluate the electron configurations below and determine which one does not represent a member of the same group or family as the others?
The electron configurations provided are: 1s² 2s² 2p⁶ 3s² 3p⁶ 1s² 2s² 2p⁶ 3s² 3p³ 1s² 2s² 2p⁶ 3s² 3p⁴ The electron configuration that does not belong to the same group or family as the others is (2) 1s² 2s² 2p⁶ 3s² 3p³, as it represents a different element with a different number of valence electrons compared to the other configurations.

Electron configuration for potassium plus chloride?
Potassium has an electron configuration of 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1. Chloride has an electron configuration of 1s^2 2s^2 2p^6 3s^2 3p^6. When potassium loses one electron to form a K+ ion, the electron configuration becomes 1s^2 2s^2 2p^6 3s^2 3p^6. When chloride gains one electron to form a Cl- ion, the electron configuration also becomes 1s^2 2s^2 2p^6 3s^2 3p^6. These ions combine in a 1:1 ratio to form potassium chloride (KCl).

What is the difference between a 2s orbital and a 3s orbital?
The main difference between a 2s orbital and a 3s orbital is their energy levels. A 3s orbital is at a higher energy level than a 2s orbital. Additionally, the 3s orbital has a larger size and higher probability of finding an electron farther from the nucleus compared to a 2s orbital.
What is the ground state configuration of 1s²2s²2p²3s²3p¹?
The ground state configuration of 1s²2s²2p²3s²3p¹ is [Ne]3s²3p¹. This notation represents the electron configuration in shorthand form, where [Ne] represents the electron configuration of the noble gas neon (1s²2s²2p⁶).
What is associated with more energy a 2s or a 3s orbital?
A 3s orbital is associated with more energy than a 2s orbital. This is because the principal quantum number (n) is higher for the 3s orbital compared to the 2s orbital, resulting in higher energy levels.
What is the correct electron configuration of the ion formed by sulfur?
Sulfur typically forms a -2 ion (S²⁻) by gaining two electrons. The electron configuration for a neutral sulfur atom is 1s² 2s² 2p⁶ 3s² 3p⁴. For the S²⁻ ion, the electron configuration becomes 1s² 2s² 2p⁶ 3s² 3p⁶, which is the same as that of argon, indicating that it has achieved a stable noble gas configuration.
What is the electron configuration of a chlorine ion in a compound of BeCl2?
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.
What is the electron configuration for sodium in its excited state?
In its ground state, sodium (Na) has the electron configuration of 1s² 2s² 2p⁶ 3s¹. When sodium is in an excited state, one of the 3s electrons can be promoted to a higher energy level, such as 3p or 4s. For example, an excited state configuration could be 1s² 2s² 2p⁶ 3s⁰ 3p¹, indicating that the electron has moved from the 3s orbital to the 3p orbital.
Evaluate the electron configurations below and determine which one does not represent a member of the same group or family as the others?
The electron configurations provided are: 1s² 2s² 2p⁶ 3s² 3p⁶ 1s² 2s² 2p⁶ 3s² 3p³ 1s² 2s² 2p⁶ 3s² 3p⁴ The electron configuration that does not belong to the same group or family as the others is (2) 1s² 2s² 2p⁶ 3s² 3p³, as it represents a different element with a different number of valence electrons compared to the other configurations.
How are electron shells filled in sodium?
In sodium (Na), which has an atomic number of 11, the electron configuration is 1s² 2s² 2p⁶ 3s¹. This means that the first shell (1s) is filled with 2 electrons, the second shell (2s and 2p) is filled with 8 electrons, and the third shell (3s) contains 1 electron. Electrons fill the shells starting from the lowest energy level (1s) and move to higher levels (2s, 2p, and then 3s) until all 11 electrons are accommodated. Sodium's single valence electron in the 3s shell makes it highly reactive, as it tends to lose that electron easily.
What is the electron configuration of an atom of silicon in an excited state?
In its ground state, silicon has the electron configuration of 1s² 2s² 2p⁶ 3s² 3p². When silicon is in an excited state, one or more electrons are promoted to higher energy levels. For example, one possible excited state configuration could be 1s² 2s² 2p⁶ 3s¹ 3p³, where an electron from the 3s orbital has been excited to the 3p orbital.
What orbital do the outmost electrons of sodium fill?
The M orbital, there's only 1 electron in it.
What is the electron configuration of ccl4?
The electron configuration of CCl4 is 1s^2 2s^2 2p^6 3s^2 3p^2. This means that the carbon atom has 2 electrons in the 1s orbital, 2 electrons in the 2s orbital, 6 electrons in the 2p orbital, 2 electrons in the 3s orbital, and 2 electrons in the 3p orbital.
