Why is bromine a nonmetal?
Bromine is a non-metal with seven valence electrons in the outermost shell and has a tendency to gain an electron to complete its octet. Thus, is very reactive in nature and is thus, present in a diatomic form in its elemental state. via
Is BR a metal nonmetal or semimetal?
Bromine is non metal .. via
Is boron a metal or nonmetal or metalloid?
Boron is a non metallic element and the only non-metal of the group 13 of the periodic table the elements. Boron is electron-deficient, possessing a vacant p-orbital. It has several forms, the most common of which is amorphous boron, a dark powder, unreactive to oxygen, water, acids and alkalis. via
Is bromine a poison?
Bromine works by directly irritating the skin, mucous membranes, and tissues. The seriousness of poisoning caused by bromine depends on the amount, route, and length of time of exposure, as well as the age and preexisting medical condition of the person exposed. via
Is California a nonmetal?
Calcium (Ca) is an active metal and react with water at room temperature. Such metals are stored in kerosene. Calcium is an alkaline earth metal having atomic number 20. The metal is used in aluminium alloys for bearings. via
Is BR a nonmetal?
Smelly element No. 35, bromine, is a fairly abundant element but has a rare property: it is the only nonmetal to exist in liquid form at room temperature, and one of only two elements (the other being mercury) that is liquid at room temperature and pressure. Bromine is very harmful to the atmosphere. via
What is the largest atomic mass?
Oganesson has the highest atomic number and highest atomic mass of all known elements. via
Are metalloids dull and brittle?
Metalloids are metallic-looking brittle solids that are either semiconductors or exist in semiconducting forms, and have amphoteric or weakly acidic oxides. Typical nonmetals have a dull, coloured or colourless appearance; are brittle when solid; are poor conductors of heat and electricity; and have acidic oxides. via
Is iodine a metal or nonmetal?
As a pure element, iodine is a lustrous purple-black nonmetal that is solid under standard conditions. It sublimes (changes from a solid to a gaseous state while bypassing a liquid form) easily and gives off a purple vapor. Although it is technically a non-metal, it exhibits some metallic qualities. via
Is Si a metal?
Silicon the semiconductor
Silicon is neither metal nor non-metal; it's a metalloid, an element that falls somewhere between the two. via
Which non-metal is lustrous in nature?
Complete step-by-step answer:
Some non-metals are also lustrous in nature, such as iodine, graphite, diamond etc. Hence, the name of a non-metal having the property of lustre is iodine. via
What is a group of 13 called?
13 = "baker's dozen" – Kristina Lopez. Jan 20 '17 at 21:35. via
Which group does only contain metals?
In the periodic table which is a representation of all the 118 elements in a tabular form featuring all the characteristics be it physical or chemical, presence of radioactivity etc was proposed by Mendeleev, the group in the periodic table in which it contains only the metals is Group 2A. via
Which metalloid has the highest atomic mass?
Leonardion is the metalloid with the greatest atomic mass. Sheldonium has the lowest atomic mass. via
