Introductionm70a0a008939b9932_1528450127855_0Introduction

Answer the introductory questions for the lesson:

1. What is matter consist of?

2. What is the electric charge?

3. What properties does an electric charge have?

Procedurem70a0a008939b9932_1528446435040_0Procedure

The atom is made up of a positively charged nucleus and a negatively charged electron sphere around it.
Electrons circulating at different distances from the nucleus form electron shells. The number of shells is variable. However, we are able to determine how many electrons are on a given shell.

Task

From the available materials, create a model of the oxygen atom. Use the information that there are 8 neutrons and 8 protons in the nucleus of the atom, and the electrons are circling around the nucleus: 2 in the closer orbit and 6 in the further orbit.

Lesson summarym70a0a008939b9932_1528450119332_0Lesson summary

Atoms consist of the nucleus and the electrons surrounding it. In the nucleus there are nucleons: protons and neutrons. Neutrons are electrically neutral particles; protons carry a positive electric charge and electrons - negative. In an electrically neutral atom, the number of protons and electrons is the same. In this case, the total charge of protons and electrons is zero. Atoms with the number of electrons different from the number of protons are called ions that are atoms having an electric charge. The properties of atoms depend mainly on the number of protons in the atomic nucleus. Groups of atoms with the same number of protons in the nucleus and different number of neutrons are referred to as the isotopes of a given element (determined by the number of protons). Atoms are the basic elements building matter from the point of view of chemistry and remain the smallest particles distinguished by chemical methods. They do not change in chemical reactions.m70a0a008939b9932_1527752263647_0Atoms consist of the nucleus and the electrons surrounding it. In the nucleus there are nucleons: protons and neutrons.
