Atomic number: The number of protons in the nucleus of an atom determines an element's atomic number.

                                                            Or

The number of protons in an atom,called the atomic number. atomic number (Z)

 In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1. All carbon atoms, and only carbon atoms, contain six protons and have an atomic number of 6. Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same.

Atomic Struccture:  Matter has mass and takes up space. Atoms are basic building blocks of matter, and cannot be chemically subdivided by ordinary means.

Example: S,H,O,N etc.

There are 90 naturally accuring atom is the World.25 atom exiest(man maded).

Atoms are composed of three type of particles: protons, neutrons, and electron.

            Electron= -ve charge

            Protons = + ve charge

            Neutrons= (0)neutral

Both the protons and neutrons reside in the nucleus. Protons have a postive (+) charge, neutrons have no charge --they are neutral. Electrons reside in orbitals around the nucleus. They have a negative charge (-).

Ewers started to write poetry when he was 17 years old. His first noticed poem was an obituary tribute to the German Emperor Frederick III.
Ewers earned his Abitur in March 1891. He then volunteered for the military and joined the Kaiser-Alexander-Gardegrenadier-Regiment No. 1, but was dismissed 44 days later because of myopia.
Ewers's literary career began with a volume of satiric verse, entitled A Book of Fables, published in 1901. That same year he collaborated with Ernst von Wolzogen in forming a literary vaudeville theatre before forming his own such company, which toured Central and Eastern Europe before the operating expenses and constant interference from censors caused him to abandon the enterprise. A world traveler, Ewers was in South America at the beginning of World War I, and relocated to New York City, where he continued to write and publish.
Ewers' reputation as a successful German author and performer made him a natural speaker for the Imperial German cause to keep the United States from joining the war as an ally of Britain. Ewers toured cities with large ethnic German communities and raised funds for the German Red Cross.
During this period, he was involved with the "Stegler Affair". American shipping companies sympathetic to the fight against Imperial Germany reportedly aided the British in identifying German-descended passengers traveling to Germany to volunteer for the Kaiser's army. Many were arrested and interned in prison camps by the British Navy; eventually, German volunteers often required false passports to reach Europe unmolested. Ewers was implicated as a German agent by one of these ethnic Germans, Richard Stegler
