Sand may vary in composition from nearly pure silicon dioxide, gypsum, or basalt, to varying degrees of impurity from mixture with other sediments. Sand is composed of small grains or rock particles or minerals, not a single element.
Truth be told, 'sand' is really just a description of grain size of any solid. However, sand is usually used to refer to silica sand (the stuff found on beaches and deserts and used to make glass etc.). This is not made of a single element, but of a compound, silicon dioxide.
No, sand is not a living thing. Living things are made of cells.
No. Sand is principally silica SiO2 with impurities typically iron(III) oxide which give it the typical reddish color.

A compound is different from an element in that a compound is made up of several elements. An element is a base atom only. Think of a compound as a living room set and an element as a couch only.
Oxygen is an element. This means that it is composed of only one kind of atom, and it takes two atoms of oxygen to make one molecule of oxygen. A compound is composed of more than one kind of element. A simple example is carbon dioxide which is composed of one atom of carbon and two atoms of oxygen. A mixture is composed of more than one kind of compound.
Yes, for example, there's diamond which is composed entirely of the element carbon or sulfur which composed entirely of (yup... you guessed it) sulfur.
Graphite is a naturally occurring mineral that is composed of the element carbon (C). Graphite is made up of lots and lots of layers of carbon laid one on top of the other, and it is one allotrope of this element. Diamond, another natural mineral, is also made up of carbon. It is likewise an allotrope of that element, just as graphite is.
It is silicon and oxygen that make up sand. Most sand is silicon dioxide, or SiO2. Quartz is the most common of a family of minerals made up of silicon dioxide called silicates. It is one example of a form of silicon dioxide.
native element
An element is composed of only one kind of atom. A compound is composed of atoms of more than one element.
A substance that is composed of only one kind of matter is called an element. The smallest particle of an element is called an atom.
No, a compound is a substance composed of two or more different elements chemically bonded together in a fixed ratio, such as water (H2O) or carbon dioxide (CO2). An element consists of only one type of atom, such as oxygen (O) or hydrogen (H).

Element
It is known as an element. An element is a substance that is made up of only one type of atom, characterized by a unique atomic number on the periodic table.
An element is composed of only one type of atom. Compounds are composed of different types of atoms (different elements) that are chemically combined.
Matter also may composed of one element only as Coal, Graphite and Diamond are only Carbon.
A compound is different from an element in that a compound is made up of several elements. An element is a base atom only. Think of a compound as a living room set and an element as a couch only.
Matter with only one particular kind of atom is known as an element. These atoms can either be located individually or combined into larger units. An example of this would be the notion that carbon is an element, because at it's pure substance state it's composed of only carbon atoms.
