The correct answer is Release of large amount of heat and radiation.
U-235, which makes up just over 0.7% of natural uranium, is relatively uncommon; uranium is nearly 100 times more frequent than silver.Because uranium-235, one of the radioactive metal's isotopes, is the only naturally occurring isotope capable of supporting a nuclear fission process, radioactive metal is special. Nuclear power facilities, as well as the nuclear reactors that power ships and submarines, can be powered by uranium that has been "enriched" to have a higher proportion of U-235. In nuclear weapons, it can also be applied. Examples of extremely unstable fission fragments produced by uranium-235 fission events caused by neutron absorption include the barium and krypton nuclei. These pieces nearly instantly split into barium-144 and krypton-89 by releasing three neutrons between them.

A) LITHIUM is the least reactive alkali metal
B) FRANCIUM is the most reactive alkali metal
C) BERYLLIUM is the least reactive alkaline earth metal
D) RADIUM is the most reactive alkaline earth metal
E) TENNESSINE is the most reactive halogen
For E it might also be Astatine because Tennessine is a fairly new
Answer: D) 1 lone pair, square pyramidal
Explanation:
Formula used : ![\text{Number of electrons}=\frac{1}{2}[V+N-C+A]](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electrons%7D%3D%5Cfrac%7B1%7D%7B2%7D%5BV%2BN-C%2BA%5D)
where,
V = number of valence electrons present in central atom = 7
N = number of monovalent atoms bonded to central atom = 5
C = charge of cation = 0
A = charge of anion = 0
Now we have to determine the hybridization of the 
molecule.
![\text{Number of electrons}=\frac{1}{2}\times [7+5+0-0]=6](https://tex.z-dn.net/?f=%5Ctext%7BNumber%20of%20electrons%7D%3D%5Cfrac%7B1%7D%7B2%7D%5Ctimes%20%5B7%2B5%2B0-0%5D%3D6)
Bond pair electrons = 5
Lone pair electrons = 6-5 = 1
The number of electrons are 6 that means the hybridization will be 
and the electronic geometry of the molecule will be octahedral .
But as there are five atoms around the central iodine atom, the sixth position will be occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be square pyramidal.
Answer:
NaCl
Explanation:
because He which is helium gas its an element alone,
Cl which is chlorine is a single element,
B which is Boron and its a single element,
but NaCl which is simply called table sugar is the combination between Na, sodium and Cl, chlorine , so its called a compound not an element.
Answer:
False.
Explanation:
(5 kilometers / 30 minutes), you could then say that in 60 minutes (one hour) you would be traveling at (10 kilometers / 60 minutes)...
Therefore, it is unlikely that you would be traveling at (6 kilometers / hour), so the answer should be... False.
