How many electrons are present in an uncharged atom with its 1s, 2s, 2p, 3s, 3p and 4s subshells filled and with five electrons

marshall27 [118]

Explanation

The orbital quantum number of an atomic subshell determines the maximum number of electrons it can contain. For example:

Each $s$ orbital $(l = 0)$ holds up to $4 \; l + 2 = 2$ electrons
Each $p$ orbital $(l = 1)$ holds up to $4 \; l + 2 = 6$ electrons
Each $d$ orbital $(l = 2)$ holds up to $4 \; l + 2 = 10$ electrons

The atom in question here contains four fully-occupied $s$ orbitals, two fully-occupied $p$ orbitals along with $5$ electrons in a partially-occupied $d$ orbital. It thus contains

$4 \times 2 + 2 \times 6 + 5 = 25 \; \text{electrons}$

What is the most important use of an elements atomic number

Setler [38]

Answer:

Atoms of each element contain a characteristic number of protons and electrons. The number of protons determines an element's atomic number and is used to distinguish one element from another.
