Engr. Musa D. Abdullahi was born in Katsina, Nigeria, in 1941. He had his Primary and Secondary education in Nigeria. He obtained BSc degree in physics from the University of Manchester, England, in 1965. He was the first person to obtain a postgraduate degree, in Electronics and Telecommunication, from Ahmadu Bello University, Zaria, Nigeria, in August 1968. He taught at Ahmadu Bello University, Zaria, from 1968 to 1972 and thereafter joined the Nigerian Pubic Service. He retired from the Nigerian Civil Service in August 2000. He was a senior lecturer in electronics and telecommunication at Federal University of Technology, Minna, Nigeria, from 2000 to 2007. He was the Pro-chancellor of Umaru Musa Yar’adua University, Katsina, from 2007 to 20017. He is a member of the Nigerian Institute of Physics, Fellow of the Nigerian Society of Engineers, Fellow of the Academy of Engineering and Member of the Order of Federal Republic of Nigeria (MFR). He is now a Visiting Chief Lecturer in the Department of Electrical and Electronics Engineering, Kaduna Polytechnic, Kaduna, Nigeria. He is a prolific contributor of papers in On-line Journals.
Abstract
If an electron of charge -e and mass m or positron of charge +e and mass m is to assume any configuration, it is most likely to be an impenetrable spherical shell of radius a with a uniform surface charge. The electric potential is constant and the electric field is zero inside the shell. From outside the shell it is as if the whole charge is concentrated at the centre of the sphere. The radial electric field outside the shell, in accordance with Coulomb’s inverse-square law, pulls the surface charge outwards while the universal space pushes it inwards to maintain a stable structure, like a bubble in the air. Such a configuration should have intrinsic energy En and mass m, where En = ½mc2, c being the speed of light in a vacuum. A positron and an electron join together to form a neutral particle called “unitron” of intrinsic energy 2En, potential energy -En and mass m. The positron, the electron and the “unitron” are proposed as the basic constituent particles of matter. On this premise, two models of the hydrogen atom are developed, a non-nuclear model identified for the gaseous state and a nuclear model for the liquid or solid state, with emission of radiation at frequencies in conformity with the Balmer-Rydberg formula. The hydrogen atom is the building block of atoms of elements and molecules of compounds.
