Atoms—and the protons, neutrons, and electrons that compose them—are extremely small. For example, a carbon atom weighs less than 2 × 10−23 g, and an electron has a charge of less than 2 × 10−19 C (coulomb). When describing the properties of tiny objects such as atoms, we use appropriately small units of measure, such as the atomic mass unit (amu) and the fundamental unit of charge (e). The amu was originally defined based on hydrogen, the lightest element, then later in terms of oxygen. Since 1961, it has been defined with regard to the most abundant isotope of carbon, atoms of which are assigned masses of exactly 12 amu. (This isotope is known as “carbon-12” as will be discussed later in this module.) Thus, one amu is exactly
1
12
of the mass of one carbon-12 atom: 1 amu = 1.6605 × 10−24 g. (The Dalton (Da) and the unified atomic mass unit (u) are alternative units that are equivalent to the amu.) The fundamental unit of charge (also called the elementary charge) equals the magnitude of the charge of an electron (e) with e = 1.602 × 10−19 C.
A proton has a mass of 1.0073 amu and a charge of 1+. A neutron is a slightly heavier particle with a mass 1.0087 amu and a charge of zero; as its name suggests, it is neutral. The electron has a charge of 1− and is a much lighter particle with a mass of about 0.00055 amu (it would take about 1800 electrons to equal the mass of one proton. The properties of these fundamental particles are summarized in Table 3. (An observant student might notice that the sum of an atom’s subatomic particles does not equal the atom’s actual mass: The total mass of six protons, six neutrons, and six electrons is 12.0993 amu, slightly larger than 12.00 amu. This “missing” mass is known as the mass defect, and you will learn about it in the chapter on nu

16. In a model of an atom, electrons move in circular orbits around a nucleus. Which statement about the electrons is correct? A The electrostatic force on the electrons is away from the nucleus. B The acceleration of the electrons is towards the central nucleus. C The speed of the electrons varies continuously. D The velocity of the electrons remains constant.
Jawaban:
B. The acceleration of the electrons is towards the central nucleus.
Penjelasan:
B. Percepatan elektron menuju inti sentral. Elektron bergerak dalam orbit melingkar di sekitar inti dan ditarik oleh gaya elektrostatik dari inti. Gaya ini menyebabkan elektron bergerak menuju inti, sehingga memiliki percepatan arah inti. Kecepatan elektron dapat bervariasi tergantung pada energi orbitnya, tetapi kecepatannya tidak selalu konstan karena dipengaruhi oleh gaya yang bekerja pada elektron.
