WebAn atom with an unequal number of protons and electrons is called an ion. An ion with more electrons, which have a negative charge, than protons, which have a positive charge, is negative and called an anion. An ion with more protons than electrons is positive and called a cation. You can remember this through the phrase "cat-ions are paws-itive."

WebIsotopes are atoms of a given chemical element that have different numbers of neutrons in their nuclei. For example, while all atoms of the element oxygen have eight protons in their nuclei, those oxygen atoms may have eight, nine, or ten neutrons. The different numbers of neutrons in the nucleus distinguishes the three isotopes of oxygen. Web7 dec. 2015 · Ionizing radiation comes from radioactive atoms, many of which occur naturally in the environment. Radioactive atoms, just like any other form of matter, can be gas, liquid, or solid. Atoms are the building blocks of matter. Their structure determines their elemental and chemical properties.

WebA molecule is comprised of two or more chemically bonded atoms. The atoms may be of the same type of element, or they may be different. Atoms can readily gain or lose electrons. If electrons are lost or gained by a neutral atom, a charged particle is formed called as an ion. Option C is true. Atoms are always neutral in nature. WebDescription. The combining capacity, or affinity of an atom of a given element is determined by the number of hydrogen atoms that it combines with. In methane, carbon has a valence of 4; in ammonia, nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1.Chlorine, as it has a valence of one, can …
