The element lithium (Li) has 3 protons and 3 electrons. The element fluorine (F) has 9 protons and 9 electrons. An atom of the e
Naddik [55]

When an atom of the element lithium (Li) transfers an electron to an atom of the element fluorine (F), then the bond results between the atoms is ionic bond.

<h3>what is chemical bond? </h3>

A chemical bond is defined as the bond which holds atoms together in molecules.

Bonds arise due to the electrostatic forces present between positively charged atomic nuclei and negatively charged electrons.

<h3>Types of chemical bond</h3>
  1. Ionic bond
  2. Covalent bond
  3. Coordinate bond

<h3>What is Ionic bond ? </h3>

Ionic bond is defined as the transfer of electron from one atom to another atom.

Since, electron transfer from lithium to fluroine. Thus lithium get positive charge and fluorine occupy negative charge.

Thus, the bond form between lithium atom and fluorine atom is ionic bond.

Can someone how to do these problems!!
Novosadov [1.4K]
You can use the follwing equations.
pH=14-pOH
pOH=-log[OH⁻]

a)  pOH=-log10⁻¹²
     pOH=12
     pH=14-12
     pH=2

You can also use these equations:
[H⁺]=K(w)/[OH⁻]    (K(w)=1.01×10⁻¹⁴)
pH=-log[H⁺]

b) [H⁺]=(1.01×10⁻¹⁴)/10⁻²M
    [H⁺]=1.01×10⁻¹²M²
    pH=-log(1.01×10⁻¹²)
    pH=12

You can use either method.  It does not really matter.
I hope this helps.  Let me know if anything is unclear and when you do the calculations for c you should get pH=7.
