Neon is a noble or inert gas. It belongs to group 18 on the periodic table, and it is represented by Ne and atomic number 10. It has a red glow in an electric field, hence its use in neon signs. Electronegativit
What is the orbital notation for neon? Orbital Notation: An orbital notation is a specific way to show the arrangement of electrons in an atom using what are called subshells. The subshells (designated s, p, d, f, and g) hold a particular number of electrons. There are 2, 6, 10, ...
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...
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.
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.
The words valence and valency have two related meanings in chemistry. Valence describes how easily anatomorradicalcan combine with other chemical species. This is determined based on the number of electrons that would be added, lost, or shared if it reacts with other atoms. ...
In an element, the numbers of electrons and protons are equal. Moreover, since they have opposite charges, they cancel each other out and keep the atom neutral. The total number of protons present in the atom of a substance is known as theatomicnumber. Atomic mass refers to a weighted ...

due to the oxygen atoms that have many pairs of unshared electrons. Substances that are soluble in oil and water, such as lecithin, are known as emulsifying agents. Phospholipids also play an important role in the body. Because they are able to form lipid bi-layers, phospholipids are a maj...
What neutral atom is isoelectronic with the Br− ion? Isoelectronic Species:Two species are isoelectronic if they have the same number of electrons. Atoms can either gain or lose electrons resulting in the formation of charged species called ions. These ions may have the same number of ...
