An atom's configuration based on its number of electron ends at 3p2. another atom has eight more electron starting at 3p. what would be the remaining configuration3p24s23d63p64s23d23p63 d24s23p23d64s2

Answer is: 3p63d24s2.

This element is titanium (Ti).

Titanium has atomic number 22, it hass 22 protons and 22 electrons.

Electron configuration of titanium atom: ₂₂Ti 1s²2s²2p⁶3s²3p⁶3d²4s².

First fill 3p orbital with 6 electrons (4 left), than 4s with 2 electrons and last 3d with 2 electrons.

The atomic number (proton number) uniquely identifies a chemical element.

Titanium is  transition metal with a silver color.

b) 3p⁶4s²3d²

Explanation:

According to the Aufbau principle, electrons are arranged in orbitals such that the lower energy orbitals are filled first followed by the higher energy orbitals. The increasing energy order of orbitals is:

1s < 2s < 2p < 3s < 3p < 4s < 3d < 4p

where the s, p ,d  orbitals can accommodate a maximum of 2,6 and 8 electrons respectively.

It is given that the valence electron configuration of the first atom is: 3p²

The second atom has 8 more electrons than the first. Now, p-orbitals can take a maximum of 6 electrons, therefore based on the energy ordering, 4 additional electrons will go to fill up the 3p orbital. The next higher up is the 4s which will accommodate 2 electrons. The remaining 2 electrons will go the 3d orbital resulting in a final configuration of:

3p⁶4s²3d²
