    Solution

    According to the question the correct option will be option ‘B’ because John Dalton considered that "all matter is composed of small particle called the atom."

    According to Dalton,

    - Atom is the smallest indivisible part of matter which takes part in the chemical reaction.

    - Atom is neither created nor be destroyed.

  • Question 2
    1 / -0

    Which of the following particle mass is equal to the atomic mass unit?

    Solution

    According to the question the correct option will be option ‘A’ because Neutrons are the particle with no electrical charge, its mass is equal to one atomic mass unit.

  • Question 3
    1 / -0

    around the nucleus the sections are available are called-

    Solution

    According to the question the correct option will be option ‘C’ because shells or orbits around the nucleus

  • Question 4
    1 / -0

    According to Dalton's atomic theory, atoms of a given element are identical in which of the following-

    Solution

    According to the question the correct option will be option ‘A’ because According to atomic theory, atoms of a given element are identical in size and chemical properties.

  • Question 5
    1 / -0

    Nucleus, which contains-

    Solution

    According to the question the correct option will be option ‘C’ because the central part of an atom is called nucleus, which contains both protons and neutrons.

  • Question 6
    1 / -0

    The atom is indivisible was proposed by:

    Solution

    According to the question the correct option will be option ‘B’ because John Dalton considered that "all matter is composed of small particle called the atom."
      According to Dalton,
    -Atom is the smallest indivisible part of matter which takes part in the chemical reaction.

  • Question 7
    1 / -0

    correctly represents symbol for chlorine in Berzelius system is-

  • Question 8
    1 / -0

    Dalton suggested that atoms were indestructible and unchangeable to elaborate-

    Solution

    According to the question the correct option will be option ‘A’ because Atoms cannot be subdivided, created or destroyed into smaller particles when they are combined, separated or rearranged in chemical reactions. The whole matter remains conserved in the form of reactants changing to products.

  • Question 9
    1 / -0

    Smallest particles of matter which cannot be further divided molecules are-

  • Question 10
    1 / -0

    If combining atoms of a compound have nearly similar electro negativities the bond between them is called-

    Solution

    According to the question the correct option will be option ‘B’ because A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.
    So, combining atoms of a compound have nearly similar electro negativities the bond between them is covalent.
