An ionic bond is formed between lithium and bromine.
Ionic compounds are formed by the complete transfer of electrons between the atoms. The atom which gains electron(s) forms anion whereas loss of electron(s) results in the formation of cation. They are bonded to each other by electrostatic force of attraction between the negatively and positively charged atoms.
While writing the ionic chemical formula for binary ionic compound the rules are:
- Writing the chemical symbol of the metals and non-metals involved in the compound formation.
- The charge i.e. the absolute value of oxidation number of each metal is written on respective atoms.
- The charge i.e. the absolute value of oxidation number are cross-multiplied that is the charge of first ion becomes the subscript of second ion and vice versa.
Hence, in the writing of ionic chemical formulas, the value of each ion's charge is "crossed over" in the crossover rule.
Answer:
the rest is lost largely through metabolic processes as heat.
Explanation:
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level;
Answer:
The molar mass and atomic mass are essentially the same for an element
Explanation:
The molar mass of a substance can be obtained by dividing the mass of the substance by the no of moles of the substance present.
The atomic mass of an element is the number of protons and neutrons present in the substance.
These two measurements usually give the same values because they both make reference to the 1/12th the mass of carbon-12 for their measurement.
Because they both have the same reference point, though they have different calculating procedures, the results obtained will be similar.
