Where is boron’s and carbon’s fifth electron located

Chemistry
1 answer:
AleksandrR [38]4 years ago
4 0

Answer:

  • <u><em>Both fitth electons are located on a 2p orbital.</em></u>

Explanation:

The electrons fill the orbitals of the atom in increasing order of energy level. Using Aufbau's mnemonic rule you can find the order of filling:

  • 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ . . .

Thus, the firs two electrons are located on the 1s orbital, the next two electrons are on the 2s orbital, and the <em>the fifth, electron of </em>both <em>boron and carbon is located </em>on a 2p orbital.

When a metal reacts with a nonmetal, the metal will...
Svet_ta [14]

Answer : The correct option is, (a) lose electrons and form a positive ion

Explanation :

Metals : These are the elements that easily loose electrons and forms cations.

They require less energy to loose electrons because electrons are loosely bound to the nucleus.

Non-metals : These are the elements that easily gain electrons to form an anion.

They require more energy to loose electrons because the electrons are tightly bound to the nucleus.

As per question, when a metal reacts with a nonmetal, the metal will lose electrons and form a positive ion and non-metal gain electrons and form a negative ion.

Hence, the correct option is, (a)
