<u>Answer:</u> The isotope produced after the transmutation process of Cf-249 and C-12 is 
<u>Explanation:</u>
Transmutation is defined as the process where one chemical isotope gets converted to another chemical isotope. The number of protons or neutrons in the isotope gets changed.
The chemical equation for the reaction of Californium-249 nucleus with Carbon-12 nucleus follows:
In a nuclear reaction, the total mass and total atomic number remains the same.
<u>To calculate A:</u>
Total mass on reactant side = total mass on product side
249 + 12 = A + 4
A = 257
<u>To calculate Z:</u>
Total atomic number on reactant side = total atomic number on product side
98 + 6 = Z + 0
Z = 104
Hence, the isotope produced after the transmutation process of Cf-249 and C-12 is
a compound is a pure substance made up of two or more elements chemically combined a molecule is defined as the smallest particle of an element which can exist separately elements are pure substances which can not be split into simple substances by chemical means the atom is defined as the smallest particle of an element which can take part in a chemical change so I think the difference between the molecule of a compound is bigger than the molecule of a compound
The answer is c, relying on renewable energy sources
Answer:
Detail is given below
Explanation:
Atomic radii trend along group:
As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.
As the size of atom increases the ionization energy from top to bottom also decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.
In A we can see that there is one positive charge and force of attraction is 2.30×10⁻⁸ N and distance is 0.10 nm
In B we can see that negative charge is further away from nucleus because of greater distance thus force of attraction will be less. 0.58×10⁻⁸ N
In C this distance further increases and force also goes in decreasing 0.26×10⁻⁸ N.
