What family is Lutetium in?
Rare Earth Metals
What is Group 4 on the periodic table called?
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member.
What is Group 3 of the periodic table?
Group 3 is the first group of transition metals in the periodic table. This group is closely related to the rare-earth elements. The group is also called the scandium group or scandium family after its lightest member.
What is Group 5 on the periodic table called?
pnictogens
Is Sulphur a metal or nonmetal?
sulfur (S), also spelled sulphur, nonmetallic chemical element belonging to the oxygen group (Group 16 [VIa] of the periodic table), one of the most reactive of the elements. Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water.
What is Group 13 on the periodic table called?
Boron group element
What is the most important metalloid?
silicon
What do all elements in group 13 have in common?
The group 13 elements consist of six elements. They are boron (B), aluminium (Al), gallium (Ga), Indium (In), thallium (Tl), and element 113. The commonest property of the group is that each one of the elements has three electrons in the outer shell of their nuclear structure.
Which group does only contain metals?
Group 2A
Which is the most electropositive element?
Fluorine (shown in red) is the most electronegative (least electropositive) element (EN = 4.0). Cesium and francium (shown in blue) are the least electronegative (most electropositive) elements (EN = 0.7).
Is lead a metal?
Lead (Pb), a soft, silvery white or grayish metal in Group 14 (IVa) of the periodic table. Lead is very malleable, ductile, and dense and is a poor conductor of electricity.
Is pencil lead metal?
Pencil lead is made of graphite which is a form of carbon. As such “pencil lead” is a non-metal.
Why is lead more common than gold?
So to narrow down and answer your question: Lead (Pb) tends to be more abundant than Gold (Au) because it has an even number of protons in its nucleus (82 versus 79) and its inner electron shells are filled (Basic Metal versus Transition Metal).
Where is lead found in the earth?
earth’s crust
How is lead removed from the body?
Most of the lead that enters the body is excreted in urine or through biliary clearance (ultimately, in the feces).
How is lead removed from the earth?
Lead is released into the air during burning coal, oil, or waste. Once lead gets into the atmosphere, it may travel long distances if the lead particles are very small. Lead is removed from the air by rain and by particles falling to land or into surface water.
What is the main source of lead?
How does lead get in the air? Sources of lead emissions vary from one area to another. At the national level, major sources of lead in the air are ore and metals processing and piston-engine aircraft operating on leaded aviation fuel. Other sources are waste incinerators, utilities, and lead-acid battery manufacturers.
