Only H and Br form Polar Covalent Bond.

Covalent bonding:

Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.

1. Polar Covalent Bond

2. Nonpolar Covalent Bond

1. Polar Covalent Bond:

A Polar Covalent Bond is created when the shared electrons between atoms are not equally shared. This occurs when one atom has a higher electronegativity than the atom it is sharing with. The atom with the higher electronegativity will have a stronger pull for electrons (Similiar to a Tug-O-War game, whoever is stronger usually wins). As a result, the shared electrons will be closer to the atom with the higher electronegativity, making it unequally shared.

2. Nonpolar Covalent Bond:

A Nonpolar Covalent Bond is created when atoms share their electrons equally. This usually occurs when two atoms have similar or the same electron affinity. The closer the values of their electron affinity, the stronger the attraction. This occurs in gas molecules; also known as diatomic elements. Nonpolar covalent bonds have a similar concept as polar covalent bonds; the atom with the higher electronegativity will draw away the electron from the weaker one.

Here H and H and N and N form Non-polar covalent bonds. Na and Br form the ionic bond.

“What was the toughest decision you ever had to make?” that means they want to gauge your ability of decision even if there is really hard to choose between any two.

They want to hear on what circumstances what will be your priorities and values you take while taking a decision which can effect a lot and most important to it.

Your decision skills are shown to interviewer that you answer will reflect. You must be accurate in your answer and try to explain the conditions and evidences upon which you taken such decision. Also you can tell how those decisions are beneficial for you in further life.

Best Answer for “What was the toughest decision you ever had to make?”

There are 2 toughest decisions that I ever made in my life.

The first one is about to choose my career. I want to be an engineer but my parents planned for me something else because of financial problems. At that time this decision was toughest for me to choose parents planned career path or my own. But I go against to my parents path and tried my best to get the scholarship from college, which I also did giving my best performance.

Second decision that I have taken is to choose between job and higher studies. In this I have chosen to do job only. I have to learn more within the job and get an experience in my field. I also want to emphasize my skills and gain more knowledge in reputed company.

A segment of the financial market in which financial instruments with high liquidity and very short maturities are traded. The money market is used by participants as a means for borrowing and lending in the short term, from several days to just under a year. Money market securities consist of negotiable certificates of deposit (CDs), bankers acceptances, U.S. Treasury bills, commercial paper, municipal notes, federal funds and repurchase agreements (repos).

No. of  sweets each student get = 20% of 65 = 13

No. of sweets each teacher get = 40% of 65 = 26

No. of sweets distributed to 65 students =  13 × 65 = 845

No. of sweets distributed to 4 teachers = 4 × 26 = 104

Therefore, the total no. of sweets there = 845 + 104 = 949.
