The element in question is Sodium
An atomic mass unit is defined as 1/12 th of the mass of carbon-12 atom.
The mass of an atom is mainly due to its protons and neutrons in the nucleus.
Weight of a proton is 1.6 x 10^-27 kg
Weight of a neutron is 1.6 x 10^-27kg
However weight of an electron is 9 x 10^-31kg and hence is negligible in calculation of amu
It is given that weight is 23 AMU and number of protons is 11
The protons in a nucleus also act as atomic number of the periodic table
Proton number 11 is the atomic number of Sodium
Hence the element is Sodium

If gravity is the ONLY force acting on an object, then the force of
Earth's gravity produces acceleration of 9.8 meters per second²
downward. That number doesn't change, and it doesn't depend
on the mass or weight of the object.
If there are any other forces acting on the object at the same time,
like air resistance or some other kind of friction for example, then
all bets are off, and we can't say what the object's acceleration will
be in that case.
Answer:
Molecular compounds consist of two or more nonmetals. The nonmetals that make up a molecular compound are held together by covalent/molecular bonds. Covalent bonds is known as the "sharing" of valence electrons between two or more chemical species. Valence electrons are shared so that the atoms of the compound can become stable, much like how ionic bonds transfer valence electrons between atoms to achieve stability.
