Most societies punish children for acting out in a bad way. What they do not think of is why they are acting out. It could be just to get attention‚ but most of the time‚ it is something deeper. Their attitude comes from an emotional attachment to an unstable family. An unstable family is a family that has an absentee parent‚ is inconsistent‚ or yields a child with behavioral issues. An unstable family is a family that often times has an absentee parent. “Over the course of the twentieth

The dropping of the atomic bombs on Hiroshima and Nagasaki remains among the most controversial events in modern history. Historians have actively debated whether the bombings were necessary. What effect they had on bringing the war in the Pacific to an end and what other options were available to the United States. As American policymakers struggled with how to use a powerful new technology and what the long-term impact of atomic weaponry might be‚ not just on the Japanese but on domestic politics

must lose 4 electrons (to become a noble gas). So that is why Zr4+ is formed. Compare the stability of the zr atom and zr ion. the electron configuration for Zr is [Kr] 4d2 5s2. Ions are formed by losing electrons in outer shells to obtain more stable electron configurations like those of noble gases. By losing 4 electrons‚ it would have the electron configuration of the noble gas‚ Kr. So that is why the Zr 4+ ion is

The Periodic Properties of Atoms The Periodic Table: In the 1870’s‚ the Russian chemist Mendeleev developed the periodic table‚ based upon the relationship between the atomic weights of the elements and their chemical properties. As one ascends from lightest to heaviest elements‚ there is a periodic recurrence of chemical properties. For example‚ the elements with atomic numbers 2‚ 10‚ 18‚ 36‚ 54‚ and 86 all are chemically inert (the noble gases)‚ while those with atomic numbers one greater 3‚ 11

The atom is a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons. Atoms lack a well-defined outer boundary‚ so their dimensions are usually described in terms of an atomic radius. This is a measure of the distance out to which the electron cloud extends from the nucleus. However‚ this assumes the atom to exhibit a spherical shape‚ which is only obeyed for atoms in vacuum or free space. Atomic radii may be derived from the distances

Atoms‚ Molecules and Elements Atoms‚ molecules and elements are the building blocks of everything we can see‚ hear‚ and touch. Though not visible to the naked eye‚ it is the combination of millions of these tiny substances that make us who and what we are today. Many elements make up the world around us‚ and each element reacts differently to its surroundings. The definition of reactivity as pertained to chemistry states‚ “The relative capacity of an atom‚ molecule‚ or radical to undergo a chemical
