Soal Latihan Bab Materi (Atom, Ion, Molekul) - Quiz

Soal latihan ini digunakan untuk mengetahui pemahaman siswa mengenai Materi (Atom, Ion, Molekul)


Questions and Answers
  • 1. 

    Suatu atom atau kumpulan atom yang bermuatan listrik disebut…

    • A.

      Atom

    • B.

      Molekul

    • C.

      Ion

    • D.

      Unsur

    Correct Answer
    C. Ion
    Explanation
    An ion is a charged atom or group of atoms. It can be positively charged, called a cation, or negatively charged, called an anion. When an atom gains or loses electrons, it becomes an ion. This charge is due to the imbalance between the number of protons and electrons in the atom. Therefore, an ion is the correct answer because it refers to a charged atom or group of atoms.

    Gabungan antara atom-atom yang tidak sejenis mengakibatkan terbentuknya. . .

    • A.

      Ion

    • B.

      Atom

    • C.

      Molekul unsur

    • D.

      Molekul senyawa

    Correct Answer
    D. Molekul senyawa
    Explanation
    When atoms of different elements combine, they form compounds called molecules. These molecules are made up of two or more different types of atoms bonded together. This process is known as chemical bonding. Therefore, the correct answer is "Molekul senyawa" which translates to "compound molecules" in English.

    Materi yang tersusun atas atom-atom sejenis yaitu. . . .

    • A.

      Tembaga

    • B.

      Gula pasir

    • C.

      Garam dapur

    • D.

      Gas Hydrogen

    Correct Answer
    A. Tembaga
    Explanation
    Materi yang tersusun atas atom-atom sejenis adalah tembaga.

  • 4. 

    Jika atom netral melepaskan elektron, maka atom tersebut akan menjadi ion positif (kation).

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    When a neutral atom loses an electron, it becomes a positively charged ion, also known as a cation. This occurs because the atom now has more protons than electrons, resulting in a net positive charge. Therefore, the statement "Jika atom netral melepaskan elektron, maka atom tersebut akan menjadi ion positif (kation)" is true.

  • 5. 

    Atom merupakan bagian yang terkecil dan tidak dapat dibagi lagi dengan reaksi kimia biasa adalah pendapat dari Thomson.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Thomson's opinion was that atoms are not the smallest and indivisible particles and can be divided further through ordinary chemical reactions. This contradicts the statement given in the question, which states that atoms are the smallest and cannot be divided further. Therefore, the correct answer is False.

    Rate this question:

  • 6. 

    Setiap molekul unsur tersusun dari empat atom unsur.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because it states that every molecule of an element is composed of four atoms of that element. This implies that the molecule is a tetramer, meaning it consists of four identical subunits. This is a valid and accurate statement about the composition of elements at the molecular level.

    Jumlah neutron dan elektron yang dimuliki oleh atom P adalah.....

    • A.

      15 dan 31

    • B.

      16 dan 31

    • C.

      16 dan 15

    • D.

      15 dan 16

    Correct Answer
    C. 16 dan 15
    Explanation
    The correct answer is 16 and 15. The atomic number of an element represents the number of protons in its nucleus. Since the atomic number of P is 15, it means that it has 15 protons. The mass number of an element represents the total number of protons and neutrons in its nucleus. Since the mass number of P is 31, it means that it has 31 - 15 = 16 neutrons. Therefore, the correct answer is 16 and 15.

    Perhatikan data berikut ini : 1.    KOH 2.    NaCl 3.    HNO3 4.    KNO3 5.    HCl Yang merupakan senyawa asam adalah nomor ….

    • A.

      1 dan 3

    • B.

      2 dan 5

    • C.

      3 dan 4

    • D.

      4 dan 5

    Correct Answer
    C. 3 dan 4
    Explanation
    Senyawa asam adalah senyawa yang dapat melepaskan ion H+ (ion hidrogen) ketika dilarutkan dalam air. Dari data yang diberikan, HNO3 (asam nitrat) dan KNO3 (asam nitrat) merupakan senyawa asam karena keduanya dapat melepaskan ion H+ ketika dilarutkan dalam air. Oleh karena itu, jawaban yang benar adalah nomor 3 dan 4.
