Phosphorus and sulfur are elements 15 and 16 in the periodic chart and selenium and tellurium are in the same group as sulfur. Sulfur was not covered in the persons edition, but they have been added in this edition because of the importance of sulfur compounds.

What do phosphorus and sulfur have in common?
They have the same number of protons. Transcribed Image Text:What do the clements sulfur (S), nitrogen (N), phosphorus (P), and bromine (Br) have in common? A. They are noble (inert) gases.
Which element would have similar physical and chemical properties as sulfur?
oxygen, sulfur, selenium, tellurium, polonium.. …it have SIX valence electrons, and the element can be reduced to form sulfide ion S2− ….
Which element is chemically most similar to phosphorus?
nitrogen group element, any of the chemical elements that constitute Group 15 (Va) of the periodic table. The group consists of nitrogen (N), phosphorus (P), arsenic (As), antimony (Sb), bismuth (Bi), and moscovium (Mc).
What type of bond is phosphorus and sulfur?
There are 4 phosphorus atoms. Each phosphorus atom is connected to 3 or 4 atoms, at most one of which is phosphorus. Each sulfur atom is connected to 1 or 2 atoms, which must all be phosphorus. The pictures seem pretty consistent about showing a ‘double bond’ when a sulfur atom is connected to just 1 phosphorus.
What’S the difference between phosphate and sulfate?
A sulfate compound’s molecular structure contains a metal or radical plus SO4, or one sulfur atom and four oxygen atoms. A phosphate compound molecule contains a metal plus one phosphorus atom and four oxygen atoms, or PO4.
Are sulphur and phosphorus metals?
Sulphur, sulphur, all halogens, phosphorus, hydrogen, oxygen, selenium, nitrogen, and noble gases are also non-metals. Non-metals are found to the left of halogens and to the right of metalloids in the periodic table. Noble gases and halogens are also referred to as non-metals because they are non-metals as well.
Which is more acidic phosphorus or sulfur?
Sulfur Oxides Sulfurous acid is also a relatively weak acid, with a pKa of around 1.8, but slightly stronger than the two phosphorus-containing acids above.
What role does sulphur and phosphorus plays in steel?
The Phosphorus present in Austenitic stainless steels increases strength. However, it has a detrimental effect on corrosion resistance and increases the tendency of the material to crack during welding. Sulphur (S): When added in small amounts Sulphur improves machinability.
What element has the most similar physical and chemical properties to the element bromine?
Element having atomic number 35 is bromine. Both chlorine and bromine lies in the same group therefore they have similar properties.
What element is will have the most similar physical and chemical properties to the element nitrogen?
Explanation: Well, it’s Group 15. The mnemonic for this Group is, no passers by , i.e. nitrogen, phosphorus, arsenic, antimony, bismuth .
What element will have the most similar physical and chemical properties to the element potassium?
The elements of potassium and sodium have similar chemical properties because they have the same number of valence electrons and form +1 ions.
Which 2 elements have the most similar chemical properties?
Li and Na are in the same group and have very similar properties.
Which two elements have chemical properties that are similar?
The elements in the first column of the Periodic Table (other than hydrogen) are known as Group 1A metals, or alkali metals. When you compare the chemical properties of these elements (lithium, sodium, potassium, rubidium, cesium, and francium), what you’ll notice is that they are all remarkably similar.
Which elements has the most similar chemical properties?
The elements that have the most similar chemical properties are those in the same group, or column of the periodic table. Elements are placed in order of atomic number and end up in vertical groups that have the same number of valence electrons and therefore similar chemical properties.
Why phosphorus and sulfur are exceptions to the octet rule?
Here the sulfur atom has six electron pairs in its valence shell. An atom like phosphorus or sulfur which has more than an octet is said to have expanded its valence shell. This can only occur when the valence shell has enough orbitals to accommodate the extra electrons.
Why does sulfur ignite at a higher temperature than phosphorus?
Sulfur: sulfur consists of S8 rings of atoms. The molecules are bigger than phosphorus molecules, and so the van der Waals attractions will be stronger, leading to a higher melting and boiling point.
Whats the difference between phosphate and phosphorus?
Definition. Phosphorus: Phosphorus is a multi-valent nonmetal chemical element of the VA group. Phosphate: Phosphate is a chemical derivative of the phosphoric acid, containing the phosphate ion (PO3−4). Formally, any salt of a phosphorus oxoacid is a phosphate.
What is the chemical makeup of phosphate?
Formula and structure: The chemical structure of phosphate is PO43-, where a central phosphorous atom is bond to four oxygen atoms, one of the bonds is a double bond and the other three oxygen atoms have simple bonds and over such oxygen a negative net are present, thus the ion is trivalent and with a tetrahedrical …
Are there phosphates in shampoo?
In cosmetics and personal care products, the Sodium Phosphate ingredients are used in the formulation of bath products, colognes, dentifrices, mouthwashes, hair conditioners, hair dyes and colors, permanent waves, shampoos, makeup and skin care products.
How do you separate sulphur iron and phosphorus?
1) Spread the sample over paper & move bar magnet over it. Iron is stuck to bar magnet while sulphur, phosphorus are left behind. 2) Remaining mixture is dissolved in carbon disulphide. Sulphur being soluble in CS2 is filtered & phosphorus is left in residue.
What is the effect of phosphorus and sulphur in cast iron?
7. What is the effect of phosphorus and sulphur in cast irons? Explanation: Although sulphur stabilizes cementite, it causes brittleness. The same is true for phosphorus, due to which both elements are limited to a minimum quantity.
Why phosphorus and sulfur should not be kept at room temperature?
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. It is also extremely toxic, even in very small quantities. (See Hazard warnings below.)
Is phosphorus acidic or basic?
Phosphorus is a soft base so the complexes most often involve a soft metal atom or ion.
Why Sulphuric acid is more stronger than phosphoric acid?
Based on pKa, sulfuric acid is the strongest acid. The smaller the pKa value the stronger the acid. All of the pKa values for sulfuric acid are less than those of phosphoric acid, hence sulfuric acid is the strongest acid.
