In this Science and Technology textbook, you will be able to study the fundamental concepts of science and technology from a different point of view through the medium of the different branches of ______.

The basic purpose of this textbook Science and Technology Part-1 can be said to be 'Understand and explain to others' the science and technology that relates to our ______ life.

While studying the concepts, principles and theories in science, do make the effort to understand their connection with day to day ______.

While studying from this textbook, use the sections 'Can you recall?' and 'Can you tell?' for ______.

You will learn science through the many activities given under the titles such as 'Observe and discuss' and 'Try this' or 'Let's try this.Make sure that you perform all these ______.

Many ______ have been included in the textbook. Carry out these experiments yourself, following the given procedure and making your own observations.

The metallic character of elements increases while going down the ______

While going from left to right within a period the outermost shell ______ the same

The positive charge on the nucleus goes on ______ while the atomic radius goes on decreasing

The tendency of atom to lose valence electrons decreases within a period from left to right due to increasing ______ charge

Music is created by the variety in the use of these notes.Be Mg Ca Zn Sr Fa (Ma) So (Pa) La (Dha) Ti (Ni) B Al Cr Y Ce & La C Si Ti In Zr N P Mn As O S Fe Se 2.2 Newlands’ Octaves Many limitation were found in Newlands’ octaves.This law was found to be applicable only up to ______.

Newlands fitted all the known elements in a table of 7 X 8 that is 56 boxes.Newlands placed two elements each in some boxes to accommodate all the known elements in the table.For example, Co and Ni, Ce and ______.

Moreover, he placed some elements with different properties under the same note in the octave.For example, Newlands placed the metals Co and Ni under the note ‘Do’ along with halogens, while Fe, having similarity with Co and Ni, away from them along with the nonmetals O and S under the note ‘Ti’.Also, Newlands’ octaves did not have provision to accommodate the newly discovered ______.

The properties of the new elements discovered later on did not fit in the Newlands’ law of ______.

The Russian scientist Dmitri Mendeleev developed the periodic table of elements during the period 1869 to 1872 A.D.Mendeleev’s periodic table is the most important step in the classification of elements.Mendeleev considered the fundamental property of elements, namely, the atomic mass, as standard and arranged 63 elements known at that time in an increasing order of their atomic ______.
