(Table)You have seen that the product of two natural numbers is one or more than one bigger than each of the two natural numbers. For example,` 3xx4`= 12, `12gt4` and `12gt3` What happens to the value of the product when we multiply two proper fractions Fill the following table and conclude your observations.

You have seen that the product of two natural numbers is one or more than one is bigger than each of the two natural numbers. For example, 3xx4 =12, 12 gt 4 and 12 . What happens to the value of the product when we multiply two proper fractions? Fill the following table and conclude your observations.

Two dice is thrown at the same time. What is the probability that the sum of two numbers appearing on the top of the dice is (a) 10,(b) less than or equal to 12, ( c) a prime number , (d) multiple of '3'?

In table-3 write the names of the organisms in the appropriate box according to where i they can be found. You could put the name of one organism in more than one column. If you put the organism in the colon in 'some other place', try to mention the place where you could find it.Some examples are filled in to help you. Copy the table 3 in your notebook. Try to enhance the list as much as you can. In which column will you put a frog?

Express 2310 as a product of prime factors. Also see how your friends have factorized the number. Have they done it as you ? Verify your final product with your friend's result. Try this for 3 or 4 more numbers. What do you conclude?

Two dice, one red and one white , are thrown at the same time. Write down all the possible outcomes. What is the probability that the sum of the two numbers appearing on the top of the dice is less than or equal to 12?

It is not possible to measure the atomic radius precisely since the electron cloud surrounding the atom doesnot have sharp boundary. One practical approach to estimate the size of an atom of a non-metallic element is to measure the distance between two atoms when they are bound together by a single bond in a covalent molecule and then dividing by two. For metals we define the term "metallic radius" which is taken as half the internuclear distance separating the metal cores in the metallic crystal. The vander Waal's radius represents the overall size of the atoms which includes its valence shell in a nonbonded situation. It is the half of the distance between two similar atoms in separate molecules in a solid. The atomic radius decreases across a period and increases down the group. Same trends are observed in case of ionic radius. Ionic radius of the species having same number of electrons depends on the number of protons in their nuclei. Atomic radii of the noble gases are larger than the precedent elements of the same periods because

The sinle quantum number by Neil.s Bohr and the appearance of several spectral lines in a particular series of Hspectrum, suggest that there more than one quantum to explain all the quantized properties of an electron in a particular energy level inside the atom. If fact when the properties of the electron is transformed from Cartesian co-ordinate to polar co-ordinates then it becomes the function of r, theta and phi suggesting three independet quantum numbers. In addition to this a fourth quantum number is required to consider the spinning behaviour of an electron. The principal quantum number n suggest the orbit number in which electron revolves, Azimuthal quantum number 1 suggest the shape of orbitals, magnetic quantum number m, gives orientation of orbital in presence of external magnetic field, while spin quantum number s, gives direction of an electron about its own axis n != 0 values of "1" ranges in between 0 to (n-1), while m depends upon 1. Total number values of m = 21+1, and "m" ranges in between -1 to +1 including 0. For each electron spin will be +-(1)/(2) The two unpaired electron present in C-atom are different w.r.t their
