Which electrons are involved in bonding'?
At times the electrons involved in bonding are shared equally between the nuclei of two atoms and the bond is called a pure covalent bond. More often, however, the sharing is unequal and the electrons spend more time around the nucleus
Radioactive decay is when an unstable nucleus core of an atom emits one or more of 3 different types of particles?
Alpha radiation is when big chunks of an atom are expelled. They are typically protons or a combination of protons and sometimes neutrons.Beta radiation is when electrons are expelled from a decaying atom.Gamma radiation is when electromagnetic waves are expelled from a decaying atom.
What does high potential mean?
when water is pure and is equal to 0 .
What is intrinsic conductivity?
Intrinsic conduction is conduction in a pure semiconductor due to electrons moving from negative to positive and an equal number of holes moving in the opposite direction. referenced from Dan O'Regan "Real world leaving cert physics"
What is electric charge conducted by?
There are two methods of conducting electric charge. Metals conduct electricity because the metallic bond creates a cloud of shared electrons which are highly mobile within the metal. Electrically charged ions can also conduct electricity, so for example, salty water is a good conductor, although pure water is a poor conductor (pure water does contain ions, both H+ and OH-, but in very low concentration).
Electronically Do neutral atoms have equal numbers of electrons and protons?
Yes, this is the pure elimental form of an atom. Atoms with a charge are called Ions.
What happens to the charge of an atom when it gains electron?
The charge of the atom is no longer neutral because the number of electrons is greater than the number of protons. Because the charge of the atom is now negative, it is now not a pure element, but an ion. An ion is an element that is no longer pure because it has gained or lost electrons. The charge of the ion is negative because it has more electrons than protons, and electrons have negative charges and protons have positive charges.
What is atom and element?
an atom is the basic unit of life. it is composed of protons, neutrons, and electrons. an element is composed of a single type of atom (for example: pure gold is made up of atoms containing exactly 79 protons and 79 electrons...the number of neutrons varies depending on if the atoms are isotopes)
Why does a pure element have an oxidation number of 0?
Because the number of protons and electrons in the atoms of pure elements are equal so positive and negative charges are balanced.
What type of bond in an equal sharing of electrons?
A nonpolar covalent bond, also called a pure covalent bond, involves the equal sharing of valence electrons.
Smallest part of a pure substance?
If the pure substance is not an element, the smallest part is a molecule (which is made of atoms) for instance, pure water is made of water molecules, which are made of 2 hydrogen atoms and 1 oxygen atom If the pure substance is an element, the smallest part is an atom. (which is made of Protons, Neutrons, and Electrons) Pure hydrogen is made of atoms. A stable hydrogen atom has 1 proton, 1 neutron, and 1 electron. Protons and Neutrons can be broken down further into Quarks, Leptons, and Bosons. The Electron is a type of Lepton.

How can lead be a pure metal?
Lead is an element. Every atom in the metal is a lead atom. That makes it different from metal alloys, like bronze, the atoms within which are copper and usually tin.
What is the theory of bonding in pure metals?
Pure metals form a metallic bond, in which each atom contributes its valance electron or electrons as the case may be, to the common electron cloud shared by all the atoms of that particular piece of metal.
What is the number of free electrons and holes in a pure semiconductor at 0k?
There are no free electrons and holes in a pure semiconductor at 0k.
Can an pure element be an compound?
No. An element is a pure substance made of only one kind of atom. A compound is a pure substance made of two or more kinds of atom.
How many protons are in an atom of a pure element?
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
