    • 2 , 8 , 3

    • 2 , 8 , 7

    Correct Answer
    A. 2 , 8 , 7
    Explanation
    The given answer, 2, 8, 7, is the same as the electron configuration of element Y. This means that element Y has 2 electrons in its first energy level, 8 electrons in its second energy level, and 7 electrons in its third energy level. Since element Y has 7 valence electrons, it can form covalent bonds with other elements that have fewer valence electrons, such as an element with the electron configuration 2, 8, 2. Therefore, the correct answer is 2, 8, 2.

    Ikatan kovalen terdapat dalam senyawa ....

    • NaCl

    • KCl

    • HCl

    • BaCl2

    • MgCl2

    Correct Answer
    A. HCl
    Explanation
    The correct answer is HCl because it is a covalent compound. Covalent bonds occur when two non-metal atoms share electrons to achieve a stable electron configuration. In HCl, hydrogen shares its electron with chlorine, forming a single covalent bond. NaCl, KCl, BaCl2, and MgCl2 are all ionic compounds, where a metal atom donates electrons to a non-metal atom, resulting in the formation of positive and negative ions held together by electrostatic forces.

    Aturan duplet terdapat pada molekul . . . .

    • Cl2

    • H2

    • O2

    • N2

    • Br2

    Correct Answer
    A. H2
    Explanation
    Duplet rule states that atoms tend to gain, lose, or share electrons in order to achieve a stable electron configuration similar to the noble gases. In this case, H2 is the only molecule that has two hydrogen atoms, which can share electrons to achieve a stable configuration with two electrons in their outermost shell, similar to helium. Therefore, H2 is the molecule that follows the duplet rule.

    Senyawa kovalen non polar terdapat pada senyawa ...............

    • HCl

    • HBr

    • CCl4

    • HF

    • NH3

    Correct Answer
    A. CCl4
    Explanation
    Nonpolar covalent compounds are formed when two atoms share electrons equally. In the compound CCl4, carbon (C) forms covalent bonds with four chlorine (Cl) atoms. Since chlorine is more electronegative than carbon, the electrons in the covalent bonds are pulled closer to the chlorine atoms, creating a partial negative charge on the chlorine and a partial positive charge on the carbon. However, since all the chlorine atoms are identical and the molecule is symmetrical, the partial charges cancel each other out, resulting in a nonpolar molecule. Therefore, CCl4 is a nonpolar covalent compound.

    • Semua dapat ditarik medan magnet

    • Semua logam pada suhu kamar berwujud padat

    Correct Answer
    A. Semua dapat ditarik medan magnet
    Explanation
    The correct answer is "semua dapat ditarik medan magnet" because all metals can be attracted to a magnetic field. This is due to the presence of free electrons in the metal's atomic structure, which can easily be influenced by a magnetic field.

    Pasangan senyawa yang mempunyai ikatan kovalen adalah . . . .

    • CH4 dan H2O

    • NaCl dan KCl

    • KCl dan CH4

    • CH4 dan MgCl2

    • KOH dan NaCl

    Correct Answer
    A. CH4 dan H2O
    Explanation
    The correct answer is CH4 dan H2O. Both CH4 (methane) and H2O (water) are covalent compounds because they are formed by sharing of electrons between atoms. In covalent bonding, atoms share electrons to achieve a full outer electron shell, resulting in a stable molecule. NaCl and KCl are ionic compounds formed by the transfer of electrons, not sharing. CH4 and MgCl2 are also covalent compounds, but the given answer specifically mentions CH4 and H2O as the correct pair. KOH and NaCl are ionic compounds, not covalent.

    Jika unsur 19X bereaksi dengan 17Y akan terbentuk . . . .

    • Senyawa kovalen dengan rumus XY

    • Senyawa kovalen dengan rumus XY2

    • Senyawa ion dengan rumus XY

    • Senyawa ion dengan rumus XY2

    • Senyawa ion dengan rumus X2Y

    Correct Answer
    A. Senyawa ion dengan rumus XY
    Explanation
    When element 19X reacts with element 17Y, it forms an ionic compound with the formula XY. Ionic compounds are formed between a metal and a non-metal, where the metal loses electrons to become a positive ion (cation) and the non-metal gains electrons to become a negative ion (anion). In this case, element 19X is likely a metal and element 17Y is likely a non-metal, resulting in the formation of an ionic compound with the formula XY.

    • XY6 elektrovalen

    • XY2 elektrovalen

    • X2Y elektrovalen

    • X2Y kovalen

    • XY2 kovalen

    Correct Answer
    A. XY2 kovalen
    Explanation
    The atomic numbers of elements X and Y are 16 and 17 respectively. Since element X has an atomic number of 16, it has 6 valence electrons. Element Y, with an atomic number of 17, has 7 valence electrons. In order for both elements to achieve a stable electron configuration, they can share two electrons through a covalent bond. Therefore, the formula and type of bond formed between X and Y is XY2 covalent.
