Question

question 8 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d⁶5p³ select state number of electrons= select element= select

Explanation:

Step1: Calculate number of electrons

Sum up the exponents. $2 + 2+6 + 2+6+2 + 10+6+2+6+3=47$

Step2: Identify the element

The element with 47 electrons (equal to atomic number for neutral atom) is Silver (Ag).

Step3: Determine the state

The electron - configuration represents the ground state as it follows the normal filling order of orbitals.

Answer:

state: ground state
number of electrons: 47
element: Ag
