What is the molecular compound name for NI3?
Nitrogen triiodide is the inorganic compound with the formula NI3. It is an extremely sensitive contact explosive.
Is cr2o3 molecular or ionic?
Answer and Explanation: Cr2 O3 is named chromium (III) oxide. Chromium is a metal and oxygen is a nonmetal, so this is an ionic compound.
Which of the following is not an ionic compound?
Answer: (b) (ii) and (iii) Covalent bonding are found in non-ionic substances. Because two atoms share a pair of electrons, hydrochloric acid (HCl) and carbon tetrachloride (CCl4) form covalent bonds.
Is cro3 covalent or ionic?
covalent
Cation in high oxidation state are said to exhibit high polarisibility. Hence, CrO3 is covalent while CrO is ionic.
Is CS2 ionic or molecular?
So, is CS2 ionic or covalent? CS2 is a covalent molecule as both the carbon and sulfur atoms have nearly the same electronegativity values. The electronegativity difference among the carbon and sulfur atom is nearly 0.03, and thus the bond between them is hardly even polar.
Which of the following is ionic compounds?
Sodium chloride, sodium bromide,lithium chloride and lithium bromide are the ionic compound. Explanation: An ionic compound is composed of cation and anion and by the electrostatic force of attraction.
Is NaCl an ionic molecule?
Ionic compounds, such as sodium chloride (NaCl), are formed by a transfer of electrons that creates ions. Ions exert electrostatic force on each other, which forms ionic bonds.
Is NI3 polar or nonpolar molecule?
The molecules themselves have a trigonal (triangular) pyramid shape. They are, of course, polar.
Why NI3 is unstable?
The reason nitrogen triiodide is so unstable is down to its molecular structure – one nitrogen atom and three iodine molecules all on one side due to how the nitrogen’s electrons are arranged.
Is fe2o3 ionic or covalent?
It is represented by Fe2O3. The oxidation state of iron oxide is +3 and +2. The bond formed between iron and oxygen is due to the difference in electronegativity between the two atoms. Since iron is metal and oxygen is non-metal therefore the bonding between oxygen and iron is ionic.
Which is not a ionic compound?
Answer : Non-ionic compounds are those that have covalent bonds. Hydrochloric acid (HCl) and carbon tetrachloride (CCl4) form covalent due to sharing of a pair of electrons between two atoms.
How do you identify an ionic compound?
The most simple way to identify an ionic compound is to check if the chemical compound is made of just two elements wherein one element can be a metal (belonging to any groups 1, 2 or 3) and the second element is a non-metal, (from group 5, 6 or 7).
Is N2O ionic?
Which of these compounds would you expect to be ionic: N2O, Na2O, CaCl2, SF4? SOLUTION We predict that Na2O and CaCl2 are ionic compounds because they are composed of a metal combined with a nonmetal. We predict (correctly) that N2O and SF4 are molecular compounds because they are composed entirely of nonmetals.
Which molecule has an ionic bond?
A salt such as sodium chloride (NaCl) is a good example of a molecule with ionic bonding (see Figure 3-3). The atomic number of the element sodium (Na) is 11, meaning that a sodium atom possesses eleven protons and eleven electrons.
Why is NI3 unstable?
What does Ni3 mean in chemistry?
Nitrogen triiodide is an inorganic compound with the formula N I 3. It is an extremely sensitive contact explosive: small quantities explode with a loud, sharp snap when touched even lightly, releasing a purple cloud of iodine vapor; it can even be detonated by alpha radiation.
Is Ni3 a formula unit?
›› NI3 molecular weight. Molar mass of NI3 = 394.72011 g/mol. In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.
Is Ni3 a polar covalent bond?
Yes, it is a polar covalent bond. You have to make difference between the N-H bond and the NH3 compound. Both are polar. In the bond N-H; because of the difference in electronegativity between N- and H- atoms. And in NH3 because of the lone pair of electrons on the N-atom which makes the structure of ammonia triangular pyramid.
How many atoms are in Ni3?
Atoms Mass percent; Nickel: Ni: 58.6934: 3: 48.1063: Phosphorus: P: 30.973762: 2: 16.9245: Oxygen: O: 15.9994: 8: 34.9692
