![]() ![]() Lithium-ion batteries power everything from your mobile phone to your laptop. Negative ions in the body relax you and energize your body. Ions are sources of energy, whether in the human body or electrical gadgets. Some examples of molecular ions are NH 4 + (ammonium), OH – (hydroxide), etc. Similar to an atomic ion, a molecular ion may be molecular cation or anion. When a molecule (a group of atoms bonded together) combines with an atomic ion, the molecule gets charged and becomes an ion. So atoms find it easier to lose or gain electrons to become ions. A) more protons than electrons B) more electrons than protons C) more neutrons than protons D) more protons than neutrons. Protons are 1836 times heavier than electrons. In order to have a positive charge, an atom must have. Atom can gain of proton to get positively charged.Atom can lose a proton to get negatively charged.Atom can gain an electron to get negatively charged.Atom can lose an electron to get positively charged.There are 4 ways in which an atom can become an ion: This negatively charged ion is called anion. When an atom has more electrons than protons, it gets negatively charged. This positively charged ion is called cation. When an atom has more protons than neutrons, it gets positively charged. For example, the fluorine atom has nine protons and nine. When the number of these charged particles is the same, the atom is neutral. Negatively charged ions are created when an atom acquires enough electrons to complete a shell. ![]() So atoms are made up of charged particles (and also neutral ones). The protons and neutrons form the nucleus of the atom whereas electrons orbit around the nucleus, as shown in Figure 1.įigure 1: Electrons Revolving Round the Nucleus they have neither negative nor positive charge. Electrons are negatively charged while protons are positively charged. Sub-atomic particlesĪtom is made up of electrons, protons and neutrons. Alternately, we can say that atom is the smallest unit of matter that can exist in a stable form. Because it has lost an electron, it has more protons than electrons the overall charge of the sodium cation is positive. As we discussed in a previous post, all matter is made up of atoms. Ions are nothing but atoms or molecules with positive or negative electrical charge. ![]()
