The atomic orbital is describes using the principle quantum number followed by a letter (s, p, d or f) that describe the sublevel.
For sublevel, it has the shape of a spherical electron cloud surrounding the nucleus and it can hold up to two electrons.
Therefore, the answer to your question is 2 electrons.
        
             
        
        
        
Villi are tiny finger like projections present in the inner epithelial lining of the intestine. Each finger like villi is further divided into microvilli, which is the extension of plasma membrane of each epithelial cell of the villi. These villi and microvilli present on the inner surface of the intestine provide a greater surface area and this enhances the digestion and absorption of the nutrients. 
Therefore, the correct answer is false as a microvilli is the tiny finger like projection of the inner epithelial cells of the small intestine that has absorptive functions.
 
 
        
             
        
        
        
Answer: protons are located in the nucleus and have a positive charge. neutrons are also located in the nucleus and have a neutral charge. electrons are located in the electron cloud and have a negative charge. the electron cloud surrounds the nucleus in an atom.

Answer:
D
Explanation:
I think they would design a airplane with this new metal first because they have to find the right balance for this new type of metal. They can't just sell a airplane with a new metal that has a different weight immediately they need to test it and design it first.
