WebLogical values and text representations of numbers that you type directly into the list of arguments are counted. If an argument is an array or reference, only numbers in that array or reference are used. Empty cells, logical values, or text in the array or reference are ignored. If the arguments contain no numbers, MIN returns 0. WebIf an amount of energy greater than the work function is transferred to an electron, the barrier is overcome and the electron is freed of its bond. Conductive materials like metals have relatively low work functions.
