What is the atomic number of Fe2+?
Iron is a chemical element with an atomic number 26. A symbol Fe represents it. It is the most common element that is found on the earth.
What is the name of Fe3+?
Fe3+, also known as ferric ion or fe(iii), belongs to the class of inorganic compounds known as homogeneous transition metal compounds. These are inorganic compounds containing only metal atoms,with the largest atom being a transition metal atom.
Which is smaller in size Fe2+ or Fe3+?
Fe2+ is greater in size than Fe3+. Consider the electronic configuration of Fe2+[Ar] 3d6 and Fe3+ [Ar]3d5 (For comparison, Fe [Ar] 4s2 3d6). Fe3+ ionic radius is 63 pm, while Fe2+ has an ionic radius of 77 pm. (For comparison, the Fe atom has a radius of 140 pm.)
What is the radius of Fe 3?
The electronic configuration of the Fe atom is (Ar)(3d)6(4s)2, and it has an atomic radius of 0.126 nm. The radius of Fe2+ is 0.076 nm, and that of Fe3+ is 0.064 nm.
What is the radius of Na+?
227 pm
Which is larger F 1 or F?
F-1 is larger than F because F has a greater positive charge and electrons repel the nucleus.
Which is larger Na+ or Li+?
(iv) Li+ or Na+: Both the cations are formed from the atoms which are present in group 1. As Na atom is larger than Li atom, therefore, Na+ ion is also bigger in size than Li+ion. Atomic radius means the size of the atom i.e. the distance from the centre of the nucleus of the atom to the outermost shell of electrons.
Which is bigger Li or Li+?
A cation has less electron than the neutral form of the element. Remember that the atomic radius is dependent upon the number of electrons (i.e. high number of electrons means larger radius). Li+ has 1 electron less than Li. Therefore, Li+ is smaller than Li.
Is Li+ smaller than H?
Answer. Explanation: lithium is smaller than hydrogen as the attraction is high in lithium.
Which is bigger K+ or Cl?
In other words, K+ has bigger effective nuclear charge than Cl− , which translates to a bigger net positive charge felt by the outermost electrons. This will compress the energy levels a bit and make the ionic radius smaller for the potassium cation. Therefore, the chloride anion will have the larger atomic radius.
