The tendency of atoms of various elements to acquire stable configuration of the nearest noble gas is the cause of chemical combination.

A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.

Laws Of Chemical Combination For Elements And Compounds

• Law of Conservation of Mass. In simple terms, this law states that matter can neither be created nor destroyed.
• Law of Definite Proportions.
• Law of Multiple Proportions.
• Gay Lussac’s Law of Gaseous Volumes.
• Avogadro’s Law.

Answer

• Exothermic reactions.and endothermic reactions cause chemical bonding of atoms of elements.
• There are several types of chemical bonding. Heat and catalysts are often needed to start the chemical bonding process.
• Other combinations require extra energy to cause the molecules to bond.

Chemical bonds are forces that hold atoms together to make compounds or molecules. Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds. The ions then are attracted to each other.

The single line representation for a bond is commonly used in drawing Lewis structures for molecules. Because of the nature of ionic and covalent bonds, the materials produced by those bonds tend to have quite different macroscopic properties. By contrast, the ionic solid NaCl has a melting point of 800°C.

Ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.

In finance, a bond is an instrument of indebtedness of the bond issuer to the holders. The most common types of bonds include municipal bonds and corporate bonds. Bonds provide the borrower with external funds to finance long-term investments, or, in the case of government bonds, to finance current expenditure.

Examples of bonds include treasuries (the safest bonds, but with a low interest – they are usually sold at auction), treasury bills, treasury notes, savings bonds, agency bonds, municipal bonds, and corporate bonds (which can be among the most risky, depending on the company).

A bond is an IOU. Those who buy such bonds are, put simply, loaning money to the issuer for a fixed period of time. At the end of that period, the value of the bond is repaid. Investors also receive a pre-determined interest rate (the coupon) – usually paid annually.

A bond is simply a loan taken out by a company. Instead of going to a bank, the company gets the money from investors who buy its bonds. The company pays the interest at predetermined intervals (usually annually or semiannually) and returns the principal on the maturity date, ending the loan.

Many bond investments have gained a significant amount of value so far in 2020, and that’s helped those with balanced portfolios with both stocks and bonds hold up better than they would’ve otherwise. Bonds have a reputation for safety, but they can still lose value.
