Did you ever find out the answer I'm in dier need
Answer:
As you go down the periodic table, usually atoms get bigger because n gets bigger (there are electrons in higher shells). Effective nuclear charge does get bigger too going down the periodic table, but this effect is smaller than the change in shell.
Explanation:
Answer:
Average kinetic energy of the particles in an object.
Total energy of particles in an object.
Explanation:
Thermal energy is the _average kinetic energy of the particles in an object____ and internal energy is the ___total energy of particles in an object__.
Thermal energy is a form of kinetic energy. Kinetic energy is due the change in position of a body or the motion of a body. When we apply thermal energy to a system, the particles gain kinetic energy which causes the motion of its particles.
The internal energy of system is the sum of all the total energy of particles contained in the object. It is given as the change between the kinetic and potential energy of a system.
