What is the electron configuration of an atom with 12 electrons?

What is the electron configuration of an atom with 12 electrons?

Element Atomic number Electron configuration
neon 10 1s22s22p6
sodium 11 1s22s22p63s1
magnesium 12 1s22s22p63s2
aluminum 13 1s22s22p63s23p1

What is the correct arrangement of electrons in an atom?

Viewed simply, electrons are arranged in shells around an atom’s nucleus. Electrons closest to the nucleus will have the lowest energy. An electron will move to the orbital with lowest energy. Each orbital can hold only one electron pair. Electrons will separate as much as possible within a shell.

Which of the following best describes how an atom with atomic number 12 would behave?

Which of the following best describes how an atom with atomic number 12 would behave in terms of forming bonds with other elements? It would form ions with a +2 charge.

What describes atomic number?

atomic number, the number of a chemical element in the periodic system, whereby the elements are arranged in order of increasing number of protons in the nucleus. Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number.

What is the arrangement of electrons in the atom?

Arrangement of Electrons. Energy Levels or Shells. The simplest model of electrons has them orbiting in shells around the nucleus. Each successive shell is further from the nucleus and has a greater energy. Sub Shells and Orbitals. This model can be further refined by the concept of sub shells and orbitals.

What is the electron arrangement of oxygen at the energy level 2?

Two is the maximum number of electrons for the level so the other electrons will have to go in a higher energy level. The \\ (n=2\\) level can hold up to eight electrons so the remaining six electrons will go in the \\ (n=2\\) level. The electron arrangement of oxygen is (2, 6).

How many electrons can the N-level of an atom hold?

A maximum of two electrons can be found in the n = 1 level; eight electrons can be in the n = 2 level. Although the n = 3 and n = 4 levels show only eight electrons in this diagram, those energy levels can hold more but not until we start looking at the transition metals.

How many electrons can be found at a given energy level?

As shown in the figure below, there are multiple energy levels where electrons can be found. As the energy level increases, the energy difference between them decreases. A maximum of two electrons can be found in the n = 1 level; eight electrons can be in the n = 2 level.
