These three main transition series are included in the set of 30 elements often called the d-block transition metals….General properties of the group.
Q. Why is potassium K and not p?
The name is derived from the english word potash. The chemical symbol K comes from kalium, the Mediaeval Latin for potash, which may have derived from the arabic word qali, meaning alkali. In all cases it is the negative anion, not the potassium, which is the key to their use. …

Q. Why are transition metals not in a group?
The transition elements are unique in that they can have an incomplete inner subshell allowing valence electrons in a shell other than the outer shell. Other elements only have valence electrons in their outer shell. This allows transition metals to form several different oxidation states.

Q. Are transition metals soft or hard?
they are good conductors of heat and electricity. they can be hammered or bent into shape easily. they have high melting points (but mercury is a liquid at room temperature) they are usually hard and tough.
Q. Why do transition metals have similar properties even though they are not in the same group?
Why do transition metals have the same properties but aren’t in the same group? The reason that that elements in the same ‘group’ have similar chemical properties is because they have the same number of valence electrons.
Q. Why do transition metals only have 2 valence electrons?
It is due to the fact that valence is the electrons in the outermost shell and because the s shell fills up before the d shell of a preceding energy level they have 2 electrons in their outermost she’ll.
Q. Are transition metals good conductors?
The transition metals are in Groups 3 through 12 and include iron, copper, nickel, gold, and silver. Except for mercury, the transition metals have high melting points and high densities. They are good conductors of heat and electric current, and are very malleable.
Q. What blocks are transition elements?
d-block
Q. Where are the transition elements?
Transition elements are the elements that are found in Groups 3-12 (old groups IIA-IIB) on the periodic table (salmon-colored block in the middle of the table).
Q. What is magnesium’s atomic radius?
173 pm
Q. Which has a bigger atomic radius K or Br?
Since potassium is located at the start of period 3, and bromine at the end of the same period, potassium will have a larger atomic radius than bromine, and thus the largest atomic radius of the four given atoms.
Q. Which is smaller magnesium or chlorine?
Since chlorine’s 17 protons are greater than magnesium’s 12 protons, chlorine will have a greater effective nuclear charge to draw chlorine’s valence electrons closer to the nucleus and, thus, chlorine is expected to have the smaller atomic radius, while magnesium with the lower effective nuclear charge is expected to …
Q. Which is smaller Na+ or Mg2+?
mg2+ would be the smaller ion this is because each ion has the same number of electrons however mg2+ has a greater number of protons and therefore is more charge dense and the outer electrons feel a greater pull from the nucleus. …
