NF3 is polar in nature due to the presence of lone pair on nitrogen atom causing a distorted shape of NF3 molecule and the difference between the electronegativity of fluorine(3.98) and nitrogen(3.04) causes polarity in N-F bonds and result in a non zero dipole moment of the entire molecule. Exposure to large amounts of cobalt(II) can cause cobalt poisoning. The molar mass is 235.98g/mol. Ionic bond occurs when there is a complete transfer of electrons from one atom (metal) to another atom (nonmetal). When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again. It occurs when one atom loses electrons to another atom, each forming an ion. The higher the electron gain enthalpy, the easier it is to form an anion. The electronegative difference between the atoms determines their bond type. What is the chemical formula for cobalt bromide? Most ionic compounds tend to dissociate in polar solvents because they are often polar. In an ionic bond, electrons are localized to one of the atoms (giving it an overall negative charge), while the other atom has an overall positive charge. The compound NCl3 is an ionic compound (metal and nonmetal), and therefore does not require prefixes- -so NCl3 is nitrogen trichloride.
