A. The leftmost peak represents the valence electrons.
B. The two peaks at the right represent a total of three electrons.
C. The electrons in the ls sublevel have the smallest binding energy
D. The electrons in the 2p sublevel have the smallest binding energy
Answers
Answer:
D. Is the correct option.
Explanation:
2p level contains the electrons furthest from the nucleus in the case of Nitrogen thus it's much easier to disperse/remove the electrons from the shell due to low pull of nucleus energy.
The best explanation of how the spectrum is consistent with the electron shell model of the atom is the electrons in the 2p sub level have the smallest binding energy. Thus, option D is correct.
What is photoelectron spectrum?
Photoemission spectroscopy also known as photoelectron spectroscopy which photoelectric effect is the process in which electron are get energy from external source of energy like sunlight deals with energy measurement of energy emission or electrons emitted from solids, gases or liquids by the process of photoelectric effect,
Photoelectric effect is the process in which electron are get energy from external source of energy like sunlight and get excited and comes in excited state from the ground state due to this process continuos flow of electron is take place and after that flow of energy is takes place.
Therefore,The best explanation of how the spectrum is consistent with the electron shell model of the atom is the electrons in the 2p sub level have the smallest binding energy. Thus, option D is correct.

How many moles of carbon atoms are there in
5g of carbon?
Answers
Answer:
12 atoms of carbon
Explanation:
(6.023X10^23)/12 atoms of Carbon.
There are 0.42 moles of carbon atoms in 5g of carbon.
HOW TO CALCULATE NUMBER OF MOLES:The number of moles in a substance can be calculated by dividing the mass of the substance by its molar mass. That is;no. of moles = mass (g) ÷ molar mass (g/mol)
According to this question, the mass of carbon is 5g. The molar mass of carbon is 12g/mol.No. of moles = 5g ÷ 12g/mol
No. of moles = 0.42moles
Therefore, there are 0.42 moles of carbon atoms in 5g of carbon.

Answer: It will give up electrons, forming a positive ion.
During bonding, strontium atom will give up electrons, forming a positive ion.
STRONTIUM:
Strontium (Sr) is an element in group 2 of the periodic table. Just like every other element in group 2, strontium posseses two valence electrons in its outermost shell. Strontium will undergo bonding with other atoms by losing its two (2) valence electrons to form a cation i.e. a positively charged ion. Therefore, strontium atom will give up electrons, forming a positive ion when it undergoes bonding.Learn more at: https://brainly.com/question/21085681?referrer=searchResults

• An ecosystem refers to multiple species
• A large population of one species is a decent answer but not the best because more species would have more diverse genetics
• Lots of traits in one species is basically the same as the above bullet point
