Answer:
)Cisplatin is a medicine used in the treatment of cancer disease
2)12.3×10-⁵
3) it is defined as the number of moles of solute present in 1kg of solvent it is denoted by'm'
molality(m)= number of moles of solute/mass of solvent in kg
4)cubic metre (m3)
5)Antiretroviral drugs
6)1 amu= 1.66056×10-²⁴g which is exactly equal to one–twelth of mass of one carbon–12 atom
7)4SF
8)kilogram per cubic meter (kg/m3)
9) atomic mass unit is defined as was exactly equal to one twelth of mass of one carbon 12 atom
10)equal volumes of gases at the same temperature and pressure should contain equal number of molecules
11) number of moles of solute in one litre of the solution
12) M= number of moles of solute/volume of solution in litre
13) one mole contains exactly 6.022×10 ^ 23 elementary entities
14) reactant which is present in the lesser amount gets consumed after sometime and after that no for the reaction take place whatever be the amount of other reactant present hence the reactant which gets consumed limits the amount of product formed
15) The threshold frequency is defined as the minimum frequency of incident radiation below which the photoelectric emission is not possible completely
16) λ=hmv
17) the range of wavelength or frequencies over which electromagnetic radiation extends
18) no two electrons in an atom can have the same set of all four Quantum numbers. (or)only two electrons may exist in the same orbital and this electrons must have opposite spin
19) [Ar] 3d¹⁰ 4s¹
20) [Ar] 3d⁵ 4s¹
21) Lyman series of hydrogen atom lies in the ultraviolet region
22) in the ground state of the atom the orbitals are filled in order of their increasing energies
23) “The chemical and physical properties of elements are a periodic function of their atomic numbers”.
24) Unniloctium
25) 18th group
26) (n-1)d1–10 ns1–2.
27) The general outer electronic configuration of f block elements is (n−2)f(0−14)(n−1)d(0−1)ns2.
28) the tendency of an atom in a molecule to attract the shared pair of electrons towards it is known as electronegativity
29) the combining power of an element, especially as measured by the number of hydrogen atoms it can displace or combine
30) the distance from the centre of the nucleus to the outermost shell of the electrons in the atom of any elements is called its atomic radius
31) Fluorine has the atomic number 9 which contain 9 protons and 9 electrons. ... Thus, the radius of fluoride ions is larger than that of fluorine atoms. F and are smaller and they have less shells. Between F and ,has one more electron, which causes the radius to be bigger
32) Ionization energies decrease DOWN a Group, but increase across a PERIOD
33) An atom is highly stable when its valence orbital is completely filled or half-filled and in nitrogen, the valence p orbital is exactly half filled. ... So, the ionization energy of nitrogen is more than that of oxygen.
34) atoms can combine either by transfer of valence electrons from one atom to another or by sharing of valence electrons in order to have an octet in their valency shell this is known as octet rule
35)
