Answer:
Reduction
Explanation:
The charge on Mg goes from 2+ to 0 which means this is a reduction.
Answer:
Calculate the atomic radii of two touching or overlapping atoms.
Explanation:
No doubt, we can't find the atomic boundary of a single atom, but when atoms are in the form of pairs it becomes very easy to measure the atomic radii of two and then dividing it by 2 to get an estimate of atomic radius of a single atom.
It is also called as covalent radius which is half of the total inter-nuclear distance between two same bonded atoms (Homo-nuclear).
If two adjacent mettalic ions are joined by such pairing then the same half of the distance between the nucleus is termed as metallic radii.
It has 78 neutrons in a cesium
D. uranium: atomic number 92, mass 238, neutrons 146
238-92=146
