They both contain the same rechargeable lithium-ion battery and the same display of 4.5" x 2.31" x 0.37". They both still have the same dimensions of 4.5" x 2.31" x 0.37". Their weight is close to the same. The iPhone 4s is minutely heavier by .1 oz.‚ making it 4.9 oz. total. Although to most people

Alkali Metals Introduction Alkali metals refer to six elements belonging to the Group IA of the long form of the Modern Periodic Table‚ viz. Lithium (Li)‚ Sodium (Na)‚ Potassium (K)‚ Rubidium (Rb)‚ Cesium (Cs) and Francium (Fr). Fr is a radioactive element. These elements are called so because they form strongly alkaline oxides and hydroxides. Electronic Configuration of Alkali Metals Each of the alkali metals has one electron in their outermost (valence) shell‚ which is just outside an inert

Table are those in which the last electron enters the outermost s-orbital. As the s-orbital can accommodate only two electrons‚ two groups (1 & 2) belong to the s-block of the Periodic Table. Group 1 of the Periodic Table consists of the elements: lithium‚ sodium‚ potassium‚ rubidium‚ caesium and francium. They are collectively known as the alkali metals. These are so called because they form hydroxides on reaction with water which are strongly alkaline in nature. The elements of Group 2 include beryllium

1. PAPER BATTERY 1.1 INTRODUCTION Traditionally‚ electronics have been designed around their batteries. The batteries form a significant part of many electronic devices. Typical electrochemical batteries or cells convert chemical energy into electrical energy. Batteries based on the charging ability are classified into primary and secondary cells. Secondary cells are widely used because of their rechargeable nature. Presently‚ battery takes up a huge amount of space and contributes to a
