What is the electron configuration for helium?Electron ConfigurationElectrons determine the chemical properties of elements. But they are not just scattered around; they form energy levels, or shells. The higher the atomic number, the further the outermost shell is from the nucleus. If an atom ...
What is the number of electrons in each energy level for the element, H? What is the atomic number of carbon-12? How many electrons are in the element Rn? What is the relationship between atomic mass and atomic number? What is the difference between atomic mass and mass number?

Every element has a unique atomic number. This is the number of protons in the nucleus of each atom. What is the atomic number of this helium atom? A neutral atom must have equal numbers of protons and electrons, so the atomic number of an element also gives the number of electrons. H...
Together, protons and electrons form an atom'snucleus. A proton has a positive charge that counters the electron's negative charge. When an atom has the same number of protons and electrons, it is in a neutral state. Electrons are unique from the other particles in multiple ways. They exis...
To find the ratio of speeds of electrons in the 1st orbit of a hydrogen atom (H) to the 4th orbit of a helium ion (He⁺), we can use the formula for the speed of an electron in a given orbit:
One of the six noble gases, Helium, is widely used in the cryogenics processing industry. It has specific properties that make it suitable for cryogenics.
In addition, we now know that alpha particles are the nuclei of helium-4, containing two protons and two neutrons, and as we shall see later, they can be the product of radioactive decay. Electrons in the atom As we have seen, the number of electrons spinning around a nucleus is usuall...
Here is an easy to grasp guide to the science behind one of nature's greatest light shows, written by a geologist and experienced aurora guide.
and above the nucleus in a cloud-like formation. The protons have a positive charge, and the electrons have a negative charge. In a normal or neutral atom, the number of protons and electrons are equal. Many times but not always, the number of neutrons in a neutral atom is the same ...
