Answer:
1
Explanation:
since Na has one electron in its outer shell it has to give away that one electron in order to obtain a noble gas structure and chlorine needs to obtain one electron also to became a noble gas so it receives the electron that the sodium gave away.
Answer:
Below!
Explanation:
Isotopes are elements with a similar chemical makeup and the same atomic number, but a different atomic mass and number of neutrons . An example of this would be carbon-12, carbon-13, and carbon-14. Three isotopes of the element carbon that have the same 6 protons but have a different neutron count. A simple way to explain isotopes would be to say that they are just different "versions" of an element.
Hope this helps ya! Best of luck <3
Energy can be converted into another energy.
This statement is true.
Answer:
A. The accepted model of the atom was changed.
Explanation:
Thomson described an atom that has the protons uniformly distributed within a circular atom with the electrons embedded . However, it cannot explain the emission of electrons from the surfaces of metals like photoelectric emission. it does not explain how the particle of the atom contribute significantly to the entire mass of an atom
Answer:
Percentage of carbon of alkene is higher compared to the alkane that has the same number of carbon per molecule. Because of this, combustion of alkene will produce more sooty flame compared to their corresponding alkane and because Alkenes have a higher percentage of carbon compared to their corresponding alkane.
Explanation:
Relative atomic mass : C= 12 and H=1
Percentage of Carbon Hexane (C6H14)
Percentage of Carbon = 83.7 percent
6(12) x 6(12) +14(1) x 100 percent= 83.7 percent
Percentage of Carbon Hexene = 85.7 percent
