You can tell that the atom is in the excited state because:
- Electron configuration should follow the 2-8-8-2 rule, meaning that the inner shell should be filled before the next shell can start holding electrons.
- Instead of the atom's electron configuration being in the ground state at 2-8-8-1, electrons from the second shell have jumped to the third.
Answer:
Atoms with 5 or more valence electrons gain electrons forming a negative ion, or anion. why are outermost electrons only ones included in orbital filling diagram? they are the only ones involved in chemical reactions and bonding. ... 2s orbital is farther from the nucleus meaning it has more energy.
Explanation:
If there are no chemical controls which can be implemented at your worksite than one should wear recommended PPE for protection .
- PPE means personal protective equipment .
- PPE at the worksite is selected to reduce the risk to health and safety .
- PPE includes aprons , overalls , gloves , footwear face shields , chemical resistant glasses , and respirators .
- The PPE and administrative control measures depends upon the behavior and supervision of human .
- The efficacy of PPE depends entirely on the workers following the procedures and instructions appropriately .
