One suggestion is that the F atom is small compared to the larger Cl and Br atoms, and the lone pair electron in p z of F is readily and easily donated and overlapped to empty p z orbital of boron. As a result, the pi donation of F is greater than ...
WebBoron is a chemical element with atomic number 5 which means there are 5 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. WebFor example, the element boron is composed of two isotopes: About 19.9% of all boron atoms are 10 B with a mass of 10.0129 amu, and the remaining 80.1% are 11 B with a mass of 11.0093 amu. The average atomic mass for boron is calculated to be:
