Reactive elements have atoms that can combine to form compounds. The atoms in a compound are combined through different types of bonds, such as ionic, covalent, hydrogen, and metallic bonding. With ionic bonding, there is an exchange of electrons between atoms. Covalent bonding occurs when electrons are shared by two atoms.
What else can I help you with?
Substance in which all atoms are alike?
A substance in which all atoms are identical is called an element.
A reactive metal whose compounds make up limestone?
Calcium is a reactive metal whose compounds make up limestone, chalk, cement and teeth. Drinking milk is one way to get this mineral.
Is o3 compound or element atom or molecule compound or element or mixture or substance?
Yes....it is an element....it is an isotope...(isotope) meaning two or more forms of the same element whose atoms differ in number of neutrons... hence in mass. Example C - Carbon = Coal = Diamond -- diamond is the purest form of carbon
What is the difference between quartz and crystal?
Both quartz and rock crystal are made up primarily of silicon dioxide. The main difference between them is that rock crystal does not have any significant amount of trace elements that would color it. Quartz does contain coloring trace elements.
How many atom in 292 moles?
The number of atoms would be 292 X Avogadro's Number X number of atoms per molecule of the substance whose moles are in question. The latter value must be specified before a complete answer can be given.
What are three elements whose atoms are likely to form bonds?
Helium, neon and argon are the least likely elements to form compounds.
What is it called when two elements whose atoms are chemically bonded form?
When two elements chemically bond to form a compound, it is known as a chemical reaction. During this process, atoms from each element combine to form new molecules with different properties than the original elements.
Why do atom combine?
Atoms can combine only if they are having an incomplete valence shell. They combine to attain an octet structure. They can also share electrons. There are some elements whose atoms do not combine, they are the inert gases.
Type of matter whose atoms are all the same?
Elements
What compounds whose structure is not primarily determined by the linking together of carbon atoms?
Inorganic
What is a pure subsatce whose smallest unit is made up of atoms of more than one element?
Compounds have atoms of more than one element.Covalent Compounds have covalent bonds between the atoms as in Water (H2O), or methane (CH4).Ionic Compounds have ionic bonds between the atoms such as Salt (NaCl) which will dissociate into ions in a suitable solvent such as water to give the ions Na+ and Cl-
What is a substance produced when elements combine and whose properties are different?
That would be a compound. Combine the elements of hydrogen and oxygen, and get a compound (water) that is quite different from the two gasses you started with.
How are atoms connected to an element?
Well the connection between atoms and elements is they are a compound... Usually compounds have quite different properties (e.g. colour, texture, taste, smell and density) from the elements whose atoms they contain... For example: the compound of water is a liquid at room temperature. Water contains atoms of the elements hydrogen and oxygen, which exist in air as colourless glass - quite different to water...
Compare and contrast compounds and mixture?
a substance produced when elements combine and whose properties are different from each of the elements. that's a compound. a mixture is a composition of two or more substances that are not chemically combined with each other and are capable of being separated. a compound is like C6H12O6 or glucose (plant sugar) or H2O and a mixture is like a pizza, with many different compounds.
Elements are the basic building blocks of matter how is it possible that there are hundreds of thousands of different kinds of matter when there are just 112 elements?
The large variety of matter comes from the different ways that elements can combine and bond together. Through chemical reactions, elements can form molecules and compounds with unique properties and structures. This allows for countless combinations and arrangements of elements to create the vast array of substances we see in the world.
Organic compounds have?
Organic compounds have carbon atoms bonded to hydrogen atoms, and may also contain other elements like oxygen, nitrogen, sulfur, or phosphorus. They are found in living organisms and are the basis of many biological processes. Organic compounds can range from simple molecules like methane to complex structures like proteins and DNA.
What is a pure substance whose smallest unit is made up of atoms of more than one element?
it is mixtures not compounds
