Answer:
Check the attached one..I only draw the Dot method of Magnesium and Fluorine.. since i love chemistry ..Hope this helps you...Balance you have to do it yourself..If you didn't get the answer let me know in the comments..But you have try okay..
And an endothermic reaction, always treat heat as a reactant
2 chromosomes.
Each chromosome in the pair are pretty much the same other than the fact they have different alleles because each comes from a different parent
Answer:The atomic mass of the second isotope of an element X 17 amu with atomic number of 7 and it is represented by X-17.
Explanation:
Number of protons in isotope X-15,(p) = 7
Number of neutrons in isotope X-15,(n) = 8
Atomic mass of the isotope X-15 = (p) + (n) = 7 + 8 = 15 amu
Number of protons in second isotope of an element X,(p) = 7
Atomic number = Number of protons in an atom of an element
Number of protons in the isotopes of same element remains the same
Number of neutrons in second isotope of an element X,(n) = 10
Atomic mass of the second isotope of an element X= (p) + (n) = 7 + 10= 17 amu
The atomic mass of the second isotope of an element X 17 amu with atomic number of 7 and it is represented by X-17.
