An Atom Is Electrically Neutral

To better understand unstable atoms, it helps to appreciate what constitutes stability. In the familiar planetary model, an atom consists of a nucleus of heavy positively charged particles, called protons, and electrically neutral ones called neutrons. Orbiting the nucleus is a cloud of lighter, negatively charged electrons. An atom contains sub atomic particles electrons, protons and neutrons. Electrons are present in the outer shells. The given atom contains eleven electrons. The atom is neutral so the number of electrons will be equal to number of protons. Atom is electrically neutral because it consist of equal no of protons and electrons. If it gain electron then atom is negatively charged and if electron is kept out then the atom is positively charged. Hope it helps you. Answer: A proton and an electron have an equal amount but an opposite type of charge. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral. Ions are more stable because their valence shell is fulfilled and therefore no sharing or bonding of electrons take place. An atom is electrically neutral when it has equal numbers of protons and electrons. Further answer All atoms are electrically neutral unless something has happened that has added or removed one.

Electric charge

A basic property of elementary particles of matter. One does not define charge but takes it as a basic experimental quantity and defines other quantities in terms of it.

According to modern atomic theory, the nucleus of an atom has a positive charge because of its protons, and in the normal atom there are enough extranuclear electrons to balance the nuclear charge so that the normal atom as a whole is neutral. Generally, when the word charge is used in electricity, it means the unbalanced charge (excess or deficiency of electrons), so that physically there are enough “nonnormal” atoms to account for the positive charge on a “positively charged body” or enough unneutralized electrons to account for the negative charge on a “negatively charged body.'

Laravel docker deploy. In line with this usage, the total charge q on a body is the total unbalanced charge possessed by the body. For example, if a sphere has a negative charge of 1 × 10-10 coulomb, it has 6.24 × 108 electrons more than are needed to neutralize its atoms. The coulomb is the unit of charge in the meter-kilogram-second (mks) system of units. SeeCoulomb's law, Electrical units and standards, Electrostatics

Electric Charge

the source of an electromagnetic field that is associated with material carriers; an intrinsic characteristic of elementary particles that determines their electromagnetic interactions. Electric charge is one of the basic concepts in the science of electricity. The entirety of electric phenomena is a manifestation of the existence, motion, and interaction of electric charges.

Two distinct kinds of electric charges are differentiated and are conventionally designated as positive and negative; it has been noted that bodies (or particles) with like charges repel one another and those with unlike charges attract one another, a fact first established by C. F. Dufay in 1733–34. The charge of an electrified glass rod was designated positive, and the charge of a resin rod (specifically, an amber rod) was designated negative. In accordance with this assumption, the electric charge of an electron is negative (the Greek word elektron means “amber”).

Electric charges are discrete: there exists a minimal elementary electric charge, of which the charges of all bodies are multiples. The total electric charge of a closed physical system is equal to the algebraic sum of the charges of its constituent elementary particles (for the common macroscopic bodies these particles are protons and electrons). This total charge is rigorously preserved during all interactions and transformations of the particles in the system. The force of interaction between quiescent charged bodies (or particles) obeys Coulomb’s law. The relationship between electric charges and an electromagnetic field is defined by Maxwell’s equations.

In the International System of Units, electric charges are measured in coulombs.

An Atom Is Electrically Neutral. True False


An atom of an element is made up of three particles including, proton, electron and neutron. Neutron is a neutral particle so, does not effect the neutrality of an atom. A proton has positive charge and an electron has negative charge. The number of electrons and number of protons in an atom are equal. So, the whole positive charge of protons cancels the while negative charge of electrons in an atom. Therefore, the net charge on an atom is zero and an atom is electrically neutral.
