Why is arsenic called arsenic?
Arsenic gets its name from a Persian word for the yellow pigment now known as orpiment. For keen lexicographers apparently the Persian word in question Zarnikh was subsequently borrowed by the Greeks for their word arsenikon which means masculine or potent.
Why is arsenic a metalloid?
Arsenic is the third element in the fifteenth column of the periodic table. It is classified as a metalloid because it has some properties similar to a metal and others of a non-metal. Arsenic atoms have 33 electrons and 33 protons with 5 valence electrons in the outer shell. Arsenic exists in a number of allotropes.
How many protons does arsenic 63 have?
Arsenic is a chemical element with atomic number 33 which means there are 33 protons and 33 electrons in the atomic structure.
What country discovered arsenic?
Mineral forms of arsenic were known as early as the fourth century BC, but the German scholastic Albertus Magnus is usually accredited with the discovery of the element around 1250.
How a neutron is formed?
Neutrons are produced copiously in nuclear fission and fusion. They are a primary contributor to the nucleosynthesis of chemical elements within stars through fission, fusion, and neutron capture processes. The neutron is essential to the production of nuclear power.

Is arsenic reactive yes or no?
33As Arsenic
One is a brittle, gray metallic form and the other is a yellow, non-metallic solid. Yellow arsenic is the more reactive and unstable of the pair. Arsenic is stable, being unaffected by air, water, most acids and alkalis. Arsenic has no liquid phase; the solid sublimes directly into a vapor.
How many neutrons does selenium 75 have?
How many neutrons are in an atom of selenium 75? Since atomic number represents number of protons, that will be 34. Take the difference of the mass number and the atomic number to get the number of neutrons. So, 79-34 will get you 45 neutrons.
