A pion is an unstable particle that has an average lifetime of 26.033 nanoseconds (2.6033×10−8 seconds). This is the time interval between its creation in a nuclear process and its extinction into decay.
a pion (or a pi meson, denoted with the Greek letter pi: π) is any of three subatomic particles: π0, π+, and π−. Each pion consists of a quark and an antiquark and is therefore a meson. Pion are the lightest mesons and, more generally, the lightest hadrons. They are unstable, with the charged pions π+ and π− decaying after a mean lifetime of 26.033 nanoseconds (2.6033×10−8 seconds),
The fundamental reason for merging space and time into spacetime is that space and time are separately not invariant, which is to say that, under the proper conditions, different observers will disagree on the length of time between two events (because of time dilation) or the distance between the two events (because of length contraction). But special relativity provides a new invariant, called the spacetime interval, which combines distances in space and in time. All observers who measure the time and distance between any two events will end up computing the same spacetime interval.

Answer:
A)Chlorine and Bromine:
They are both non metal hence they form a covalent bond due to covalent bonding.
B)Potassium and Helium:
Helium ion has a small cationic radius and distorted by the potassium ion due to polarization.
C)Sodium and Lithium:
Both are metals hence they form a metallic bond since they share electrons to the electron cloud.
Answer:
The molar mass and atomic mass are essentially the same for an element
Explanation:
The molar mass of a substance can be obtained by dividing the mass of the substance by the no of moles of the substance present.
The atomic mass of an element is the number of protons and neutrons present in the substance.
These two measurements usually give the same values because they both make reference to the 1/12th the mass of carbon-12 for their measurement.
Because they both have the same reference point, though they have different calculating procedures, the results obtained will be similar.
