Answer:
i) B
ii) D
Explanation:
<em>Bond length is determined by the size of the atoms involved and the bond order </em>
A) C-I
B) H-I
answer : H-I has the shortest bond length because H has an electronegativity value of 2.2 while C has an electronegativity value of 2.5 hence the bond between H-I is greater than C - I due the electronegativity difference between H-I is greater as well.
C) H-Cl
D) H-I
answer : H-Cl has the shortest bond length due the electronegativity difference between H-CI is greater as well.
Answer:
x = 33.52 amu
Explanation:
It is given that,
Isotope A has a mass of 34 amu and an abundance of 52%, isotope B has a mass of 33 amu and an abundance of 48%.
Let x is the average atomic mass of this element. It can be calculated as follows :
So, the average atomic mass of this element is 33.52 amu.
Answer:
The atomic number
Explanation:
Transmutation refers to the conversion of one chemical element into another. A transmutation usually involves a change in the structure of atomic nuclei and this may be induced by a nuclear reaction.
Transmutation was first achieved in 1919 by Lord Rutherford when he successfully changed a nitrogen nucleus to an oxygen-18 isotope, producing a proton in the process.
Since transmutation often involves changing one atom into another, the atomic number or mass number of the original element always changes (to form a new element) in the process.
A meander is best described as a bend or curve in a stream channel.
Can u explain it more plz.
