What element is 5s24d105p4?
What element is 5s24d105p4?
tellurium
Which group has least metallic character?
If we look at the periodic table group 17 and group 18 have the least or lowest metallic character.
What is the least metallic metal?
Of solid and liquid elements at normal temperature and pressure, the least metallic are those at upper right of the Periodic Table: carbon, phosphorus, sulfur, bromine and iodine. Carbon in some of its allotropic forms has one property in common with metals; it is a good conductor of electricity.
What element is heavier than gold?
Tungsten: One Of The Heaviest Metals & A Hard Act To Follow
| Metal | Density (g/cm3) |
|---|---|
| Neptunium | 20.45 |
| Plutonium | 19.82 |
| Gold | 19.30 |
| Tungsten | 19.25 |
Which is the smallest element?
helium
How do you find the smallest number?
Calculate the smallest or largest number in a range
- Select a cell below or to the right of the numbers for which you want to find the smallest number.
- On the Home tab, in the Editing group, click the arrow next to AutoSum. , click Min (calculates the smallest) or Max (calculates the largest), and then press ENTER.
Which city is the smallest city in the world?
Vatican City
Which has the largest radius Co3+ Mn3+ fe3+ Cr3+?
Fe 3+ has highest radii because by going left to right in the periodic table , the size get decreased so .. Fe 3+ >Co3+ >Cr3+ >Mn3+ .
Which elements have the largest atomic radius?
Francium has the largest, Helium has the lowest. Atomic radius increases as you go to the left and downward due to the attraction of electrons and the nucleus in an atom….
Why is Fe2+ bigger than Fe3+?
Fe2+ will be larger than Fe3+. This is because the outermost electron in the Fe2+ ion is pulled off to form Fe3+ ion. As the electrons are removed, it reduces the repulsion increasing nuclear charge experienced by each of the other d electrons and decreases the size of the ion….
Why is Mg2+ smaller than Li+?
Interestingly, the atomic radii of Li and Mg are 1.52 and 1.60 A respectively, and here also the difference is quite small. Despite the Mg atom having a slightly larger size, the Mg2+ ion is marginally smaller in size than the Li+ ion because of its higher nuclear charge.
What is the radius of Mg2+?
0.72 A
Which is bigger Li+ or Na+?
As Na atom is larger than Li atom, therefore, Na+ ion is also bigger in size than Li+ion. (v) P or As: Both these atoms belong to group 15 of the periodic table. Since As is placed after P, therefore its size is large because atomic size increases down the group.
What is the radius of Be2+?
Ionic radius of Be2+ is _than Becc11…..
Which ion is bigger Na+ or Mg2+?
Explain your answer. 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.
