and the outermost region of the atom which holds its electrons in orbit around the nucleus, as illustrated in Figure 1. Atoms contain protons, electrons, and neutrons, among other subatomic particles. The only exception is hydrogen (H), which is made of one...
Atoms aren't just packets of matter: they contain electrical energy too. Each proton in the nucleus of an atom has a tiny positive charge (electricity that stays in one place). We say it has a charge of +1 to make everything simple (in reality, a proton's charge is a long and com...
Compounds composed of metals and non-metals contain charged species The charged species are known as ions. An ion is a charged particle and can be negatively or positively charged. Anions are negatively charged ion while cations are the positively charged ion ...
Atoms are made up of three main particles: neutrons (neutrally charged), electrons (negatively charged), and protons (positively charged). The protons and neutrons are found in the nucleus, the center of the atom, while the electrons are constantly traveling around the nucleus. The number of ...
Thomson’s Model Thomson suggested that atoms had negatively charged electrons embedded in a positive sphere. This is the first model that included smaller particles of the atom His model is similar to blueberries in a muffin Rutherford’s Model Developed the first model that included a nucleus Si...
Neutrally charged particles found in the nucleus What is an electron? negatively charged particle in the nucleus What is an electron shell? an orbit that electrons follow around an atom's nucleus What are valence electrons? electrons in the outermost shell of an atom and can participate in the...
Protons are not elementary particles; they're actually made up of even smaller particles calledquarks. Like neutrons, protons contain three quarks (two "up" quarks and one "down" quark) that are held together inside a proton by theStrong Force.Particles made of three quarks are referred to ...
