What do atoms of the same element have in common?
The common feature is that the atoms of all elements consist of electrons, protons, and neutrons.
What do atoms of the same element have the same?
All atoms of the same element have the same number of protons in their nucleus.
Is light from all elements the same?
Each atom has a set of energy levels associated with it. All of the atoms of a particular element have the same set of energy levels, but every element has a unique set of energy levels associated with its atoms. The electrons in the higher energy levels can often become excited by light, heat, electricity, etc.
How do atoms interact with light?
When light falls onto an atom the oscillations of the electromagnetic wave causes the electron to oscillate. In this fashion the atom absorbs the energy of the light. If this atom now interacts with other atoms it can pass along the photon energy (wave oscillations).
What do all atoms of the same element have in common quizlet?
Atoms of the same element all have the same number of protons but they can have different numbers of neutrons. The atomic number is the number of protons in the nucleus of the atoms in that element. The atomic mass is the average mass of the different isotopes of that element.
Do all atoms of the same element have the same atomic number?
Although all atoms of a given element must have the same atomic number, they need not all have the same mass number. For example, some atoms of carbon (atomic number 6) have a mass number of 12, others have a mass number of 13, and still others have a mass number of 14.
Do atoms radiate light?
Atoms emit light when they are heated or excited at high energy levels. The color of light that is emitted by an atom depends on how much energy the electron releases as it moves down different energy levels. Absorption is shown by the energy levels increasing as the photon gains energy.
What is light interaction?
Light–matter interactions are fundamentally quantum electrodynamical, and in many cases, are described as quantum transitions by electrons, accompanied by the emission, absorption or scattering of quanta of the electromagnetic field in vacuum (photons).
Do all atoms of the same element have the same atomic mass?
All atoms of a chemical element have the same atomic number (number of protons in the nucleus) but may have different mass numbers (from having different numbers of neutrons in the nucleus). Atoms of an element with the same mass number make up an isotope of the element.
Why do all atoms of an element have the same atomic number although they may have different mass numbers quizlet?
Atoms of each element have the same number of protons, but they can have different numbers of neutrons. Why do isotopes of the same element have different atomic masses? Isotopes of an element vary in mass because their numbers of neutrons differ.
How are atoms of the same element the same How are atoms of the same element different?
Basic principles. Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.
