I have seven valence electrons and I have two more protons than phosphorus who am I
Question:
Answers
Answer : The unknown element is, chlorine.
Explanation :
As we are given that there are seven valance electrons and two more protons than phosphorous.
As we know that, phosphorous is a non-metal which belongs to group 15.
The atomic number of phosphorous is, 15 that means there are 15 electrons in phosphorus atom.
The electronic configuration of phosphorus is:
[tex]1s^22s^22p^63s^23p^3[/tex]
As the unknown element has two more protons than phosphorus that is 15 + 2 = 17
The electronic configuration of will be:
[tex]1s^22s^22p^63s^23p^5[/tex]
The unknown element have seven valance electrons. Thus, the element will be chlorine.
Hence, the unknown element is, chlorine.
the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
