Explanation:
The speed at which a planet orbits the Sun changes depending upon how far it is from the Sun. When a planet is closer to the Sun the Sun’s gravitational pull is stronger, so the planet moves faster. When a planet is further away from the sun the Sun’s gravitational pull is weaker, so the planet moves slower in its orbit.
Physical chemistry is the area that deals with the
mechanisms, the rate, and the energy transfer that occurs when matter undergoes
a change. So the correct option for the given question is option “B”. Whenever
there is a change in the state of matter, the physical properties definitely
undergo a change. A solid matter will always have a definite shape and volume,
while a liquid has a definite volume but no shape. Gases do not have either definite
volume or shape. Chemical properties might not be affected, but physical
properties are definitely impacted when a matter undergoes change.
Hey there!
The acronym STP in chemistry stands for Standard Temperature and Pressure. At STP, the temperature will be 273.15 Kelvin (0°C or 32°F) and one mole of gas will occupy 22.4 liters of volume. Standard pressure is set at 1 atm. STP measurements are often used to solve the ideal gas formula (PV = nRT).
Hope this helped you out! :-)

Answer:
Option B= neon
Explanation:
The given electronic configuration is of neon. Neon is noble gas with atomic number 10. The noble gases configurations are used for abbreviated electronic configuration
For example, the atomic number of neon is ten and sodium is eleven. The abbreviated electronic configuration of sodium is written by using the neon abbreviation in following way:
The electronic configuration of neon is given below:
Ne₁₀ = 1s² 2s² 2p⁶
The abbreviated electronic configuration of sodium:
Na₁₁ = [Ne] 3s¹
