Answer:
An ionic bond is formed between a metal and a non-metal. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.
Explanation:
There are two types of atomic bonds - ionic bonds and covalent bonds. They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 - 200 kcal/mol). Whether two atoms can form a covalent bond depends upon their electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and negatively charged ion (anion). The bond between these two ions is called an ionic bond.
Answer:
Effects of CHD
Explanation:
With less blood flow, your heart doesn't get the oxygen it needs, and that can cause chest pain, called angina, especially when you exercise or do heavy labor It also can affect how well your heart pumps and make the rest of your body short on oxygen, too.
This is what Ik about it, I hope it helped, have a great Saturday:)
Answer:
Species 4
Explanation:
The species began to peak in population and then remained very steady

Assumingely, they sound like they are both archaebacteria. Which are found everywhere, some even on your body.
