What is the oxidation state of Cl in Cl2O3?
What is the oxidation state of Cl in Cl2O3?
+3
What is the charge of S in SO2?
S atom has six valence electrons out of which 2 remain as lone pair of electrons and 4 are shared with 2 oxygen atoms to form covalent bonds. Hence, no electron is gained and no electron is lost. So, neither negative nor positive charge is present on the S atom. Hence, the formal charge on S atom in SO2 is zero.
What charge is SO2?
The sulfur–oxygen bond has a bond order of 1.5. There is support for this simple approach that does not invoke d orbital participation. In terms of electron-counting formalism, the sulfur atom has an oxidation state of +4 and a formal charge of +1.
What are the consequences of actinide contraction?
The gradual decrease in the ionic radii with increase in atomic number of actinoids. In the actinoid series, the nuclear charge and number of 5felectrons increases by one unit. The size contraction in actinoids is greater as compared to that in lanthanoids.
What are the characteristics of the transition elements?
Properties of transition elements include:
- have large charge/radius ratio;
- are hard and have high densities;
- have high melting and boiling points;
- form compounds which are often paramagnetic;
- show variable oxidation states;
- form coloured ions and compounds;
- form compounds with profound catalytic activity;
What is the most important characteristic of the transition metals?
Transition metals, for the most part, are good conductors. They are also malleable, ductile, lustrous, and sliver-white in color. An exception to this would be copper, which is brownish red in color. Metals have another great characteristic, they easily mix.
What are the characteristics of the transition elements and why are they called transition elements?
Transition elements are those elements in which the atoms or ions (in stable oxidation state) contain partially filled d-orbital. These elements lie in the d-block and show a transition of properties between s-block and p-block. Therefore, these are called transition elements.
Why are they called transition elements?
The d-block elements are called transition elements because they exhibit transitional behaviour between s-block and p-block elements. Their properties are transitional between highly reactive metallic elements of s-block which are ionic in nature and the elements of p-block which are covalent in nature.
Why are groups 3/12 called transition metals?
Question: Why Are Transition Metals Called Transition Metals? Answer: Most of the elements on the Periodic Table are transition metals. These are elements that have partially filled d sublevel orbitals. So, they transition between metallic and nometallic properties.
Why P-block elements are called P-block elements?
The s-block and p-block elements are so called because their valence electrons are in an s orbital or p orbital respectively. They are also called Typical Elements to distinguish them from the transition and inner transition series.
What is the difference between S-Block and p block?
Hint: The s-block elements are present on one side and the p-block elements are present on the opposite side of the periodic table and involve the filling of the s and p-orbitals respectively. The s-block consists of mostly metals whereas p-block consists of both metals and nonmetals.
What does P block mean?
P block elements are in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons therefore in all there are six groups of p-block elements.
