What is electron configeration?

Answer 1

Have same electronic configuration. Example Sodium ion & Neon atom have isoelectronic configuration 2,8 Have same electronic configuration. Example Sodium ion & Neon atom have isoelectronic configuration 2,8

Answer 2

Electronic configuration refers to the number of electrons in each electron shell. There can be up to 2 electrons in the first shell, 8 in the second and third and then 18 in the fourth. You can work out the electronic configuration by looking at the periodic table: by looking at the rows you know how many shells there are and by looking at the columns you know the number of valance electrons (number of electrons in the outer shell).

Answer 3

Consider aluminum which has the atomic number 13. According to wikipedia its electron configuration in simplest form is 2, 8, 3. This means that there are two electrons in the innermost electron cloud, eight in the next one away from the nucleus and three in the outermost cloud.

Answer 4

The electron configurations of ions are isoelectronic with a noble gas, meaning they have the same electron configuration as a noble gas. Negative ions are isoelectronic with the noble gas at the end of their period or row. Positive ions are isoelectronic with the noble gas at the end of the previous period. For example, the chloride ion (Cl-) is isoelectronic with the noble gas argon at the end of period 3, whereas an aluminum ion (Al3+) is isoelectronic with the noble gas neon at the end of period 2.

Answer 5

Electron configuration refers to the distribution of electrons in an atom's electron shells or orbitals. It describes the arrangement of electrons based on their energy levels and sublevels within an atom. The electron configuration of an atom is crucial in determining its chemical and physical properties.

Answer 6

Electron configuration is the distribution of atomsâ?? electrons or molecule. It is commonly used to label the orbits of an atom in its ground state.

Answer 7

it tells how the electrons are ditributed in orbitals around the necleus.

Answer 8

electronic configuration is the distribution of electrons in the shells of a given element.
