Does the nucleus of an atom have a positive electric charge?

The nucleus of an atom has a positive charge. The nucleus of an atom has two types of particles, protons and neutrons. Protons have a positive charge but the neutrons have no charge, therefore the nucleus has a net positive charge. The positive charge of the nucleus is balanced by the negative charge of the electrons. They are found in the periphery of the nucleus where they occupy energy shells or levels that surround the nucleus. Protons do not usually move anywhere, unlike electrons. Electrons can move from atom to atom . An atom is said to be neutral if it has equal numbers of protons and electrons.

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
