Across a normal shock wave, the density of the flow increases as the shock compresses the gas. The Mach number decreases; it transitions from supersonic (greater than 1) upstream to subsonic (less than 1) downstream of the shock. This change occurs because the shock wave converts kinetic energy into thermal energy, resulting in a rise in pressure and temperature. Consequently, the flow properties adjust to accommodate the conservation of mass, momentum, and energy across the shock.
planer density is the ratio of number of atoms to area of plane .
The number of transistors in a defined square area on an IC chip.
By writing your name address and phone number on each and every piece of the device.
When you change your mobile number in Uzzap the system will send a pin code to your new number. Next time you log into Uzzap you will be prompted to enter this pin.

When going left to right across a period, the atomic number of element increases.
The number of valence electrons for the elements increases across a period, from 1 (group 1) to 8 (group 18).
they get more electrons the farther right the get
As you go down the periodic table, the density generally increases. This is because the atomic mass and atomic size of elements increase as you move down a group, resulting in a greater mass packed into a larger volume. Exceptions can occur due to fluctuations in atomic structure or intermolecular forces.
When the vertical axis represents "number of things" and the horizontal represents "volume of the thing"---slope is change in vertical over change in horizontal, so units of the slope would be "number/volume", which is density.
It decreases across a period. Since the atomic number increases, so does no. of protons and electrons. This makes the electrostatic force of attraction between electrons larger and hence the atom shrinks a bit. This makes the radius smaller.
the no. of electrons increses
That is the specific gravity of the substance.
A normal calcium atom should have 20 neutrons, but if it is an isotope the number of neutrons will change.
