The correct answer is B. He doesn’t wear goggles because he is using household chemicals.

Explanation:

Carrying out experiments especially those that imply substances such as chemicals implies following practices to guarantee safety. Because of this, in the lab you should use special clothes this includes goggles and gloves; you should clean and decontaminate your station; avoid eating, drinking or smoking and always ask your teacher for any step or procedure. This implies, the inappropriate action is "He doesn’t wear goggles because he is using household chemicals", because protection should be used all the time as even substance we use every day can be dangerous if you are closely exposed to them or if they are mixed with others.

  • <em>Bohr model:</em> The electrons are moved around the nucleus in circular definite paths (orbitals or shells). Also, he could not find or detect the exact position of electron.
  • <em>Electron cloud model:</em> It is supposed by  Erwin Schrodinger. He showed that the emission spectra of the atom is the way to detect the probability of electron position.
