Both the number of protons and the number of electrons of an atom determine
its atomic number, as in an atom ( but not in an ion ).
Explanation:
whats the question. cause I didn't see it
Atoms consist of electrons surrounding a nucleus that contains protons and neutrons. Neutrons are neutral, but protons and electrons are electrically charged. Protons have a relative charge of +1, while electrons have a relative charge of -1. The number of protons in an atom is called its atomic number.
I would say you are correct so b 4.6
In gas particles, when the temperature is increased heat energy is increased, this heat energy is converted to kinetic energy in the gas particles.
Kinetic energy is the energy associated with motion.
Kinetic energy = 1/2mv²
kinetic energy is proportional to velocity. When the gas particles gain kinetic energy, kinetic energy increasing means their velocity is also increasing.
Therefore when temperature is increased, the kinetic energy of the particles increase and the particles move faster.
However when the temperature is decreased, the kinetic energy of particles reduce, when the kinetic energy reduces the velocity of gas particles too reduce.
therefore when temperature is decreased
C. the particles move slower and their average kinetic energy decreases
