Are C and Pb in the same group?
Carbon group element, any of the six chemical elements that make up Group 14 (IVa) of the periodic table—namely, carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl).
Which element has properties most like P?
Arsenic
How do you know chemical properties are similar?
Two different elements have similar chemical properties when they have the same number of valence electrons in their outermost energy level. Elements in the same column of the Periodic Table have similar chemical properties.
What do Chalcogens have in common?
Properties the Chalcogens Share So, what do polonium and oxygen have in common? Oxygen, polonium, and the rest of the chalcogens all have six valence electrons; these are the outermost electrons, farthest away from the center of the atom.
Why are alkaline earth metals conductive?
Alkaline earth metals are placed in group II A of the periodic table and they have two valence electrons in their outermost orbit. As their ionisation potential is very low, hence they can lose their valence electrons very easily. Hence alkaline earth metals are good conductors of heat and electricity.
Why is sodium and potassium are stored in kerosene?
Sodium is a highly reactive metal and reacts vigorously with the oxygen, carbon dioxide and moisture present in the air such that it may even cause a fire. To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn’t react with kerosene.
Which element is kept in kerosene?
Sodium
Why is sodium and potassium stored in water?
Explanation: Sodium and potassium metals reacts very vigorously with water; this reaction gives out so much heat that the hydrogen evolved catches fire. Therefore, these metals are stored under kerosene.
How do we store sodium and potassium?
Sodium, potassium and lithium are stored under oil, give reason. Hint: Sodium, potassium, and lithium can lose electrons easily. Sodium, potassium, and lithium can react easily with the gases present in the air or with the moisture. The oil prevents the reaction of alkali metals with air and moisture.
In which liquid sodium and potassium are stored?
kerosene oil
Where are sodium potassium usually kept?
Sodium, potassium, and lithium are stored under oil because metals like sodium and potassium react so, vigorously that they catch fire if kept in the open. Hence, to protect them they are kept immersed in kerosene oil.
Why is phosphorus stored in water?
White phosphorus is highly reactive, and spontaneously ignites at about 30°C in moist air. It is usually stored under water, to prevent exposure to the air.
Why is white phosphorus kept in kerosene?
Phosphorus is stored in water because phosphorus is very reactive non metal. It reacts vigorously with oxygen and water. A lot of heat is generated in the reaction. It is, therefore,stored in kerosene.
What is the ignition temperature of phosphorus?
approximately 86°F
What is the ignition temperature of phosphorus Class 8?
35 °C.
What is the ignition temperature of red phosphorus?
For example, freshly prepared, bright red phosphorus is highly reactive and ignites at about 300 °C (572 °F), though it is more stable than white phosphorus, which ignites at about 30 °C (86 °F).
Why is phosphorus P4 and not p?
1 Answer. Due to larger atomic size P is unable to form pi bonds and so it is tetra-atomic in which each P atom is linked with 3 other P atoms by 3 sigma bond. But, due to smaller atomic size N forms 1 sigma and 2 pi bonds i.e. triple bonds with other N atom and exists as diatomic molecule.
Which phosphorus is most stable?
Black phosphorus
Can eating match heads kill you?
Those involved in the manufacture of the new phosphorus matches were afflicted with phossy jaw and other bone disorders, and there was enough white phosphorus in one pack to kill a person. Deaths and suicides from eating the heads of matches became frequent.
