Answer:
Explanation:
The given number is 6.02 × 10⁹. It is written is scientific notation.
As you see it has two parts:
- The first part are the digits with the decimal point after the first digit. This part is called mantissa. The mantissa can only have one digit, between 1 and 9, before the decimal point.
- The second part is a power of 10. The exponent can be either positive or negative.
If the exponent is negative means that the decimal point must be moved to the left and if the exponent is positive means that the decimal point must be moved to the right.
In the number 6.02 × 10⁹ the exponent is 9, so you must move the decimal point 9 places to the right:
- 6.02 × 10⁹ = 6.02 × 1,000,000,000 - 6,020,000,000,

Answer 1: The two most basic types of bonds are characterized as either ionic or covalent. In ionic bonding, atoms transfer electrons to each other. ... In contrast, atoms with the same electronegativity share electrons in covalent bonds, because neither atom preferentially attracts or repels the shared electrons.
Answer 2 : In ionic bonding, the atoms are bound by attraction of oppositely charged ions, whereas, in covalent bonding, atoms are bound by sharing electrons to attain stable electron configurations.
Answer 3 : Each nitrogen molecule consists of two atoms of nitrogen that are bonded by a triple covalent bond. This is a direct consequence of the fact that each nitrogen atom has 5 valence electrons. Each atom can thus complete its octet by sharing three electrons.
