The number of proton in the nucleus of an atom is its Atomic Number.
Ookay
1) T
2) T
3) F
Hope i helped :)
I think it's RbCl and CaO
Answer: An element with the same number of protons, but a different number of neutrons
Explanation:
The # of protons in an atom is what determines what atom it is (hydrogen has 1 proton, helium has 2 protons, etc ...). You cannot change the number of protons in an atom without changing what element the atom is.
The number of electrons in atoms varies greatly because electrons are constantly gained, lost, and shared during chemical reactions.
An isotope is a variation of the same element (so they must have the same # of protons) that have different masses (and therefore a different number of neutrons).
The answer is the fourth choice, "An element with the same number of protons, but a different number of neutrons"
Answer:
The correct option is: A) N₂
Explanation:
The Bond length of a chemical bond is the length of a chemical bond formed between two given atoms.
<u>Bond length is inversely proportional to the bond order</u> of the chemical bond, which is the total number of bonds between two atoms. <u>Thus as the bond order increases, the bond length decreases.</u>
A) N₂: The nitrogen-nitrogen bond in dinitrogen is a triple bond (N≡N).
Thus the bond order = 3.
B) O₂: The oxygen-oxygen bond in dioxygen is a triple bond (O=O).
Thus the bond order = 2.
C) SO₂: Sulfur dioxide is a resonance stabilized molecule and its resonance hybrid shows that the sulfur-oxygen bond in sulfur dioxide is a partial double bond.
Thus the bond order = 1.5
D) SO₃: Sulfur trioxide is a resonance stabilized molecule and its resonance hybrid shows that the sulfur-oxygen bond in sulfur trioxide is a partial double bond.
Thus the bond order = 1.33
<u>Since the bond order of N₂ is the largest, therefore, the N-N bond length is the shortest.</u>
