Atoms of different elements emit different frequencies of light due to their unique electron configurations. When electrons absorb energy, they can jump to higher energy levels; when they return to their original levels, they release energy in the form of light. The specific energy differences between these levels vary for different elements, leading to the emission of distinct frequencies or wavelengths of light, which correspond to their characteristic spectra. This phenomenon is the basis for techniques like atomic spectroscopy, allowing for element identification.
What else can I help you with?
How many different kinds of atoms occur naturally on earth and why so?
There are 118 different kinds of atoms that occur naturally on Earth, known as elements. This is because of the unique number of protons in the nucleus of each atom, which determines the element's identity. The various combinations of protons, neutrons, and electrons give rise to the different elements found in nature.
Why do different elements give off different energy signals?
Different elements give off different energy signals because each element has a unique structure of electrons surrounding its nucleus. When these electrons transition between energy levels, they emit light or energy at specific wavelengths characteristic of that element. This is the basis for techniques like atomic emission spectroscopy that are used to identify elements based on their unique spectral signatures.
What metals react with other metals what happens to the valence electrons of the metal atoms?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
What color are the protons in carbon?
Things like atoms and sub atomic particles are far too small to have colour. We perceive colours from the scattering and absorption of light. The different light frequencies give us different colours. Protons are far, far smaller than any visible light wavelengths, so they can't really be said to have any colour at all.
What are the oxidation states of the atoms in a diatonic gas?
In a diatomic gas, such as O₂ or N₂, the oxidation states of the atoms are typically zero. This is because the atoms are in their elemental form and are not combined with different elements, which would give them positive or negative oxidation states. For example, in the case of O₂, each oxygen atom has an oxidation state of 0. Similarly, in N₂, each nitrogen atom also has an oxidation state of 0.
What did Annie Jump Cannon contribute to the atomic theory?
She discovered that different atoms give off different frequencies of light.
What at the atomic level what makes elements reactive?
their atoms take,give,or share electrons with other atoms :)

What is the frequency of a hydrogen atom?
An atom doesn't have a frequency. It can vibrate with many different frequencies. It can absorb radiation of different frequencies under different circumstances. For instance, electrons moving between various energy levels absorb and release characteristic frequencies of visible and ultra-violet light, and in a magnetic field radio frequency energy can be absorbed as the nucleus moves from one spin state to another. Bonds between hydrogen and other atoms absorb energies in the infra red. All these things give spectra of various frequencies, not an individual frequency.

How can atoms make up all of substances around you?
Although there are only 90 elements, they combine in many different ways to form all of the substances around you.

Give an example of a molecule that is a compound and one that is not a compound?
Water (H2O) is an example of a compound, as it is made up of two different elements, hydrogen and oxygen, chemically bonded together. Oxygen gas (O2) is an example of a molecule that is not a compound, as it consists of two atoms of the same element bonded together.
