In general, nonmetals form covalent bonds, metals and nonmetals form ionic bonds, and metals form metallicbonds.
Non-metals are natural materials that do not generate heat or electricity and are structurally brittle, making them difficult to roll, mold, extrude, or press.
Non-metallic elements in the periodic table include hydrogen, carbon, nitrogen, oxygen, phosphorus, arsenic, and selenium.
Ioniccompounds are formed when metals and nonmetals combine, whereas covalent compounds are formed when nonmetals combine with other nonmetals.
Metal atoms have only a few electrons in their outer shell, whereas non-metal atoms have many electrons.
This means that metals are more likely to react with nonmetals. Electrons transfer from the metal to the nonmetal when it reacts with it.
Thus, there will be covalentbonding between nonmetals.

Answer:
The ionic bond is formed due to an electrostatic force of attraction between two oppositely charged ions. This bond is usually formed between a metal and a nonmetal. Prior to the electrostatic attraction, there is a total transfer of valence electrons from one atom to the other atom.

9.75 x 10^5
A number in scientific notation has the form a x 10^b where
• a is the coefficient
• b is the exponent
Here are the steps to convert a number greater than 1 to scientific notation.
a) Find the coefficient
Put the decimal point after the first digit and drop the trailing zeroes
9.75 000
The coefficient is 9.75.
b) Find the exponent
Count the number of digits after the first digit.
In 975 000 there are five digits after the 9. Therefore, the exponent is 5.
c) Write the number
We write 975 000 as 9.75 x 10^5.

Answer;
- Crystal structure
Explanation;
-Diamond and graphite are allotropes of carbon, they differ in physical properties.
-In graphite, carbon atoms are covalently bonded to form sheets or what we call hexagonal layers, and these sheets are held together by weak inter-molecular forces called vander waal forces. This makes the layers to slide over each other , a property that makes graphite soft and slippery.
-In Diamond, carbon atoms are bonded by strong covalent bonding forming a tetrahedron shaped solid of Diamond which makes it a very hard solid.
