Answer:
positive one (+1)
Explanation:
sodium having atomic mass is twenty three (23) and atomic number is eleven (11).
Sodium atom having only one electron in it's outer most shell and it is easy for atom to lose this electron from outer most shell to make itself stable.
So after losing this electron positive charge on the upper right side of the atom will occur with the number of electron lose that is Na+1 .
Answer:
V ∝ n
Step-by-step explanation:
Suppose that pressure and temperature are constant.
If you try to force more molecules of air into a balloon, the balloon will expand.
This is an example of <em>Avogadro's Law</em>: the volume of a gas is directly proportional to the number of moles (particles).
V ∝ n
Answer:
See Explanation
Explanation:
Metallic bonds involve attraction between electrons and positively charged metal ions. The metals are ionized and electrons form a sea of valence electrons. These loosely bound electrons surround the nuclei of the metals.
The presence of this sea of electrons explains the fact that metals conduct electricity and heat due to the free valence electrons.
Due to the nature of the bonding between metal atoms,metals are malleable and ductile.
Due to the strong electrostatic interaction between metal ions and electrons, the metallic bond is very strong and is very difficult to break thereby accounting for the greater strength of metals as the size of the metallic ion decreases.
<span>We can relate the average speed
of the gas molecules by its kinetic energy. The kinetic energy is the work done
by the object due to its motion. It is represented by the formula of the half
the velocity squared multiply by the mass of the object. The absolute zero
theory is the assumption that at 0 Kelvin or -273.15 degrees Celsius, the gas
molecules stop moving. It is because the temperature is severely cold enough to
allow movement of the gas molecules. The gas molecule that is closest to the
absolute zero is in cylinder B because it moves so slow and its movement is
almost near to the absolute zero theory.</span>
