A pure substance is classified by having a definite and constant composition. The substance can be either an element or a compound, but what makes the substance pure, is that it does not vary.
The concept of electronegativity deals with the power of attraction of an electron to element in a compound.2.5 = carbon2.58 = sulfurSulfur, having the higher electronegativity, will attract the electrons in the compound slightly more than carbon in the same case.If you want to measure the power of attraction to single atoms, electron affinity is used.
Golfers do not disolve sugar in their "tee". When put in tea, sugar is invisibly present, having its form dissolved:"in solution". Robert L. Wolke's book "What Einstien told his cook 2",page 420.
Hydrogen is an element having atomic number 1.It is the most plentiful element sen in stars.
The "orbit" of an electron is the energy level that electron happens to be in. When we get to particles the size of electrons, the concept of electrons following a specific path begins to fall apart. We can no longer talk about an electron being somewhere and having a specific velocity; we can only talk about the PROBABILITY of an electron being at a specific place, as well as the most likely velocity at a given orbit.

all compounds having carbon and hydrogen as an essential element are organic compounds
A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense, central, positively charged nucleus surrounded by a system of electrons. The entire structure has an approximate diameter of 10 -8 centimeter and characteristically remains undivided in chemical reactions except for limited removal, transfer, or exchange of certain electrons.
If an element is missing one electron, which is defined as having a negative charge, then the element is a positively charged ion. If an element gains an extra electron, it will have a negative charge and be a negative ion. An element with an equal number of positively charged protons and negatively charged electrons is considered to be a neutral element (in other words, no charge). By the way, no charge for this answer!
if X simply represents and unknown, then the compound would be potassium permanganate, KMnO4
A mineral is defined as a compound having a fixed chemical composition ... Thus an element is not a mineral.
It will not ionize ealily, high electronegativity willionize easily.
if a neutral atom donates an electron it will gain a positive charge. This is due to electrons having a negative charge.
When a metallic atom and a nonmetallic atom have an electron transfer to form an ion, this is known as an ionic compound. For example, salt (NaCl) an electron transfer occurs. The Na, which has 1 electron on its valence shell ( outer shell) and the Cl, which has 7 electrons on its valence shell. The Na transfers its one electron to the Cl. This therefore results in the Cl having a full valence shell; at this point Cl is negative and Na is positive. We can then conclude the NaCl is an ionic compound.
An element is a homogeneous material having a definite mass, where as a compound is also a homogeneous material, an out come of chemically bonded, mechanically inseparable, involving 2 or more elements.
Hydrogen is the simplest, lightest element. It normally occurs as "protium", the atom having one proton and one electron.
It is a measure which gives the relative mass of an element (or compound) - relative to 12C having a mass of 12.
