When atomic collisions increase, the temperature typically increases. This is because temperature is a measure of the average kinetic energy of particles in a substance, and more frequent collisions generally lead to greater energy transfer among the particles. As their kinetic energy rises, the temperature of the substance also increases.
What else can I help you with?
Why the stability decrease with increasing atomic mass?
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
Why resistance of alloys decreases with temperature?
The decrease in resistance of alloys with temperature occurs because as temperature increases, the atoms within the alloy vibrate more vigorously, causing increased collisions between electrons and atoms. This increased atomic movement disrupts the orderly flow of electrons, leading to a higher resistance.
Does an element on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
What is typically transferred during atomic and molecular collisions?
Energy.
How does atomic radii increase or decrease in the table?
Atomic radii generally increase from top to bottom within a group (with more electron shells) and decrease from left to right across a period (due to increasing nuclear charge). This trend is influenced by the balance between the increasing positive nuclear charge and the increasing number of electron shells, which can shield the outer electrons from the nucleus.
What would be the effect of a change in temperature on the resistivity?
A change in temperature generally increases the resistivity of most materials. This is because as temperature rises, the atoms in the material start to vibrate more vigorously, causing more collisions between electrons and atoms. These collisions impede the flow of electrons, resulting in an increase in resistivity. Conversely, at lower temperatures, resistivity tends to decrease due to reduced atomic vibrations and fewer collisions.
Explain how a change in temperature affects the pressure inside a container?
On an atomic scale, atoms are constantly vibrating. This vibration along with the electronic orbitals of the atom limit the minimum distance between two atoms. With increase in temperature the amplitude of this vibration increases. This leads to an increase in the minimum distance. This increase in the minimum distance manifests itself as an increase in the volume at a macroscopic scale.
How does the atomic radius increase or decrease horizontally on the periodic table?
Atomic radius decreases horizontally in periodic table. This is due to increase in nuclear charge.
What accompanies an increase in atomic number within a specific period?
An increase in atomic number within a specific period corresponds to an increase in the number of protons in the nucleus of the atom. This leads to a higher positive charge, causing the outer electrons to be more strongly attracted to the nucleus. As a result, the atomic size tends to decrease across a period as atomic number increases.
Which common factor affect both resistance as well as resistivity and how?
Temperature is a common factor that affects both resistance and resistivity. An increase in temperature generally leads to an increase in resistance and resistivity of a material. This is because higher temperature causes more atomic vibrations and collisions within the material, hindering the flow of electrons and increasing resistance.
Why the stability decrease with increasing atomic mass?
Stability depends on to proton/neutron ratio; and this ratio increase with the atomic number.
Towards the bottom of the periodic table does the atomic mass increase or decrease?
Towards the bottom, atomic mass increases. Atomic number also increases.
What is the general trend in densities for period 2?
The general trend in densities for period 2 elements of the periodic table is that densities increase from left to right. This is because elements in period 2 have increasing atomic numbers, leading to an increase in atomic mass and a decrease in atomic volume, resulting in higher densities.
What factors contribute to the decrease in ionization energy within a group in the periodic table as the atomic number increases?
as atomic number is increase the size of the atom goes on increasing as more number of electron is added to the outer most orbit so the nuclear force exerted by the nucleus on electron is less so the affinity to loose electorn is more as the atomic number is increase that is the reason ionization energy decrease with increase in atomic number
Why resistance of alloys decreases with temperature?
The decrease in resistance of alloys with temperature occurs because as temperature increases, the atoms within the alloy vibrate more vigorously, causing increased collisions between electrons and atoms.

Why do radii of atoms become smaller from sodium to chlorine?
The atomic radii decrease from sodium to chlorine due to the increase in effective nuclear charge as you move across the period. This results in a stronger pull on the valence electrons, causing the atomic size to decrease. Additionally, the increased number of protons in the nucleus as you move from sodium to chlorine also contributes to this decrease in atomic size.
