The third shell contanis one s orbital,three p orbitals and five d orbitals.Each orbital hold 2 electron so the total number of electron which can be accommodate in third shell are 18 electrons
Answer: The bond formed between magnesium and oxygen is an ionic bond.
Explanation:
An ionic bond is formed when an atom transfer its valence electrons to another atom.
Whereas, a covalent bond is formed by the sharing of electrons between the atoms.
Silicon and oxygen forms silicon dioxide. Silicon has 4 valence electrons which are shared with each oxygen atom. Hence, silicon and oxygen forms a covalent bond.
Oxygen and oxygen shares two pairs of electrons therefore, a covalent bond is formed between oxygen and oxygen.
A covalent bond is formed between carbon and hydrogen as carbon has 4 valence electrons which are shared with four hydrogen atoms.
Magnesium has 2 valence electrons which are transferred to the oxygen atom in order to complete its octet.
Therefore, the bond formed between magnesium and oxygen is an ionic bond.
<u>Answer:</u> The wavelength of light is 
<u>Explanation:</u>
To calculate the wavelength of light, we use Rydberg's Equation:
Where,
= Wavelength of radiation
= Rydberg's Constant = 
= Final energy level = 3
= Initial energy level = 6
Putting the values in above equation, we get:
Hence, the wavelength of light is
Food contamination is classified into three types: 1) Physical 2) Chemical Biological.
Physical contamination occurs if a paint chip falls into soup
It must be noted that, physical<span> contamination get into food through</span><span> poor procedural practices such as</span><span> dirt, hair, nail polish flakes, broken glass, nails, staples, plastic fragments, bones, bits of packaging, etc.</span>
