Which pair of elements has same chemical properties ?

Answer question numbers 3(a) - 3(d) on the basis of your understanding of the following paragraph and the related studied concepts: Around the year 1800, only 30 elements were known. Dobereiner in 1817 and Newlands in 1866 tried to arrange the then known elements and framed laws which were rejected by the scientists. Even after the ejection of the proposed laws, many scientists continued to search for a pattern that correlated the properties of elements with their atomic masses. The main credit for classifying elements goes to Mendeleev for his most important contribution to the early development of a Periodic table of elements wherein he arranged the elements on the basis of their fundamental property, the atomic mass and also on the similarity of chemical properties. The formula of their hydrides and oxides were treated as basic criteria for the classification of the elements. However, Mendeleev's classification also had some limitations as it could not assign the position to isotopes. He also left some gaps in the periodic table. 3(a) state Mendeleev's Periodic Law. 3(b) Why did Mendeleev leave some gaps in the Periodic table? 3(c) if the letter 'R' was used to represent any of the elements in the group , then the hydride and oxide of carbon would respectively be represented as (i) RH_4 , RO (ii) RH_4 , RO_2 (iii) RH_2 , RO_2 (iv) RH_2 , RO 3(d) isotopes are (i) atoms of an element with similar chemical properties but different atomic masses. (ii) atoms of different elements with similar chemical properties but different atomic masses. (iii) atoms of an element with different chemical properties but same atomic masses. (iv) atoms of different elements with different chemical properties but same atomic masses.

The pair of elements that have similar chemical properties are

The atoms of different elements having same mass number but different atomic number are known as isobars. The sum of protons and neutrons, in the isobars is always different.

From the list, given below, select the correct answers for [Isobars, Isotopes, Efflorescence, Hygroscopy, Charles's law, Boyle's law, Kelvin, Thermal dissociation, Thermal decomposition]. Atoms of the same element having the same atomic number but different mass numbers.

Atom with the same atomic number and different mass numbers are called

Amongst the following statements, select the set having statements which was porposed by Dalton. (1) All the atoms of a given element have identical properties including identical mass. Atoms of different elements differ in mass. (2) When gases combine or reproduced in a chemical reaction they do so in a simple ratio by volume provided all gases are at the same T & P (3) Chemical reaction involve reorganization of atoms. These are neither created nor destroyed in a chemical reaction. (4) Matter consists of indivisible atoms

Solid which do not show the same physical properties in different directions are called:

The isotopes of hydrogen have different physical properties due to difference in mass. They have almost same chemical properties with a difference in their rates of reactions which is mainly due to
