29 Apr Atomic Structure

Chemistry tuition classes in Miracle Learning Centre is very useful. If you do not understand chemistry, you must definitely attend the chemistry tuition class at Miracle Learning Centre. Let us learn about atomic structure in this chemistry tuition lesson.

Your chemistry tuition teacher at Miracle Learning Centre will teach you about atomic structure. An atomic consists of three types of particles: proton, electron and neutron. The proton is positively charged and has a similar mass as the neutron. Protons and neutrons are found in the nucleus. The electron is negatively charged and has a mass of 1/1840 of the proton. It is found in the shells outside of the nucleus.
The proton number is the number of protons in the atom. The nucleon number is the number of protons and neutrons in the atom. To find the number of neutrons, we take the nucleon number minus the proton number. The number of protons is equal to the number of electrons in a neutral atom. The positively charged ion has more protons than electrons. The negatively charged ion has more electrons than protons.

The student at Miracle Learning Centre asked, ” By looking at the periodic table, how do i tell the electronic configuration of a flourine atom? “
The chemistry tuition teacher at Miracle Learning Centre replied, ” An atom has the same number of protons and electrons. Since the proton number of flourine is 9, it should have 9 electrons. The first shell can hold a maximum of 2 electrons. The second shell can hold a maximum of 8 electrons. Hence the electronic configuration of flourine atom is 2,7.”

Miracle Learning Centre hope you have understood atomic structure and how it helps you to answer chemistry tuition questions. Do come to Miracle Learning Centre for more chemistry tuition lessons to learn more about atomic structure and chemistry.
