What else can I help you with?
The MOST electronegative element on the periodic table is?
Fluorine is the most electronegative element on the periodic table. It has the highest electronegativity value of 3.98.
If these choices which is the most electronegative element?
To determine the most electronegative element among a set of choices, one would typically refer to the Pauling scale of electronegativity. Generally, fluorine is recognized as the most electronegative element, with a value of about 4.0. If fluorine is among your choices, it is the most electronegative; otherwise, compare the electronegativity values of the remaining elements.
When will an atom be electronegative?
An electronegative atom gain electrons.
What is the most electronegative element according to periodic trends?
fluorine is the most electronegative of the elementscaesium is the least electronegativeAdditional Explanation: http://en.wikipedia.org/wiki/Electronegativity#Periodic_trendsSource: The widely quoted Pauling electronegativity of 0.7 for francium is an extrapolated value of uncertain provenance. The Allen electronegativity of caesium is 0.66.
Which element is given first the more electronegative or less electronegative?
fluorine is most electronegative and cesium is least electronegative
Does CCl2F2 have hydrogen bond?
No, CCl2F2 (carbon tetrachloride) does not have hydrogen bonds because it does not contain hydrogen atoms directly bonded to highly electronegative atoms like oxygen, nitrogen, or fluorine, which are necessary for hydrogen bonding to occur. Carbon tetrachloride only has polar covalent bonds due to the differences in electronegativity between carbon and chlorine or fluorine atoms.
How many atoms in ccl2f2?
There are a total of 9 atoms in CCl2F2: 1 carbon atom, 2 chlorine atoms, and 2 fluorine atoms.
Is ccl2f2 induced dipole dipole-dipole or hydrogen bonds?
CCl2F2 will have both Van der Waals forces and dipole-dipole forces.Hydrogen bonds only form from a Hydrogen atom, when a highly elecronegative atom (Nitrogen/Oxygen/Fluorine)
What is the electronegative value of iodine?
The electronegativity value of iodine is 2.66 on the Pauling scale.
The MOST electronegative element on the periodic table is?
Fluorine is the most electronegative element on the periodic table. It has the highest electronegativity value of 3.98.
Is aluminum more electronegative than sodium?
Aluminum is more electronegative than sodium. The electronegativity of aluminum is 1.61. The electronegativity of sodium is 0.93.
What is the use of for CCl2F2?
CCl2F2, also known as CFC-12, was commonly used as a refrigerant and propellant in aerosol sprays. However, its use has been phased out due to its contribution to ozone depletion.
What is the mass of 0.500 mol of dichlorodifluoromethane CCl2F2?
To find the mass of 0.500 mol of dichlorodifluoromethane (CCl2F2), you need to calculate the molar mass of the compound. The molar mass of CCl2F2 is 120.91 g/mol. Therefore, 0.500 mol of CCl2F2 would have a mass of 0.500 mol x 120.91 g/mol = 60.455 g.
What is most electronegative calcium or gallium?
Gallium. Ga electronegativity 1.81; Calcium 1.00.
Is hydrogen more electronegative than sulfur?
No, sulfur is more electronegative than hydrogen. Hydrogen has an electronegativity value of 2.20 on the Pauling scale, while sulfur has a value of 2.58. This means sulfur has a greater tendency to attract electrons in a chemical bond compared to hydrogen.
Which has least electronegative value krypton or lithium?
Lithium has the least electronegative value. Electronegativity generally decreases as you move down a group in the periodic table. Krypton is in the same period as lithium but is a noble gas and has a very low electronegativity value compared to lithium.
What is one mole of freon CCl2F2 the chemical ratio of carbon to chloride to fluorine is 2-1-2?
One mole of freon CCl2F2 contains 1 atom of carbon, 2 atoms of chloride, and 2 atoms of fluorine. The chemical ratio of carbon to chloride to fluorine in freon CCl2F2 is 1:2:2.
