1 Answer. Elements and compounds are similar in that they are both made of atoms and in some cases molecules.

Answer: Elements primarily combine to form compounds through two main types of chemical bonding: ionic bonding and covalent bonding. Nonmetal elements are typically short electrons and will covalently bond to each other by sharing electrons.

Almost all the elements combine to form compounds, although the reactivity may vary from element to element. These combinations take place because almost all the elements are unstable. By gaining or losing electrons, ionic compounds are produced. Sharing of electrons results in the formation of covalent compounds.

no metals cannot combime to form a compound…. This is because they donates electrons to form cations… thus two metals cannot form a compound as no other metal would be ready to accept electrons…

A compound contains atoms of different elements chemically combined together in a fixed ratio. A mixture is a combination of two or more substances where there is no chemical combination or reaction. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds.

Globally, more than 350,000 chemical compounds (including mixtures of chemicals) have been registered for production and use. A compound can be converted to a different chemical substance by interaction with a second substance via a chemical reaction.

That is because a molecule can be made up of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule. However, all compounds are made up of two or more different types of atoms. Elements are rarely found in their pure state; compounds are much more common.

Answer: The ionic compounds are usually hard because the ions are held by strong force of attraction as the positive and negative ions are strongly attracted to each other and difficult to separate.

In this lesson, we looked at some of the more common physical properties of compounds, including color, odor, melting point and boiling point. A chemical property is a characteristic of a substance that can only be observed during some type of chemical reaction.

If the compound contains three elements one of which is oxygen then the compound name will end in –ate or –ite, eg Calcium carbonate contains calcium, carbon and oxygen….Rule three.

A compound is a chemical substance made up of two or more elements.

• fermium (Enrico Fermi),
• lawrencium (Ernest Lawrence),
• roentgenium (Wilhelm Röntgen),
• rutherfordium (Ernest Rutherford),

The name of a compound with two elements has two words. To get the first word we use the name of the first element, or the element to the left of the formula. To get the second word we use the name of the second element and change the suffix to “ide” at the end of the word. What if there is more than one atom?

For binary ionic compounds (ionic compounds that contain only two types of elements), the compounds are named by writing the name of the cation first followed by the name of the anion. For example, KCl, an ionic compound that contains K+ and Cl- ions, is named potassium chloride.

The aptly named titin weighs in at a molecular weight of 3 million and consists of a continuous chain of 27,000 amino acids, making it 20 to 50 times larger than the average-size protein. Like the Titans of Greek mythology, titin is known not only for its size but for its strength.

Protons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.

Originally Answered: What is the largest molecule? DNA. In nature as well as synthesized, the largest molecules are polymers. In cells, some protein molecules consist of 16000 monomers for a total of roughly 160000 atoms (beta galactosidase).

The chemical formula for the protein is C169723H270464N45688O52243S912. If you’ve taken Organic Chemistry, then you know you are in for a real treat in pronouncing the IUPAC name. It is 189,819 letters long, which could make it the longest word in the English language.
