What is Cr on the periodic table?
Why is Cr electron configuration different?
Why does Cr have a unique configuration? There are two main reasons: The 3d orbital is slightly lower in energy, and minimizing repulsions in the 4s orbital by moving one of the 4s electrons to a close-lying 3d orbital minimizes the ground-state energy of chromium. What element is 3s23p1?
| A | B |
|---|---|
| neon | [He] 2s2 2p6 |
| magnesium | [Ne] 3s2 |
| aluminum | [Ne] 3s2 3p1 |
| silicon | [Ne] 3s2 3p2 |
How do you write kr?
listen); plural: kronor; sign: kr; code: SEK) is the official currency of Sweden. Both the ISO code "SEK" and currency sign "kr" are in common use; the former precedes or follows the value, the latter usually follows it but, especially in the past, it sometimes preceded the value. How do you write kr electron configuration? So after the 3d. 10 we get 4p. 1 2 3 4 5 6 4 p6 and there's krypton right there in the 4p6.
What is electron configuration of kr 36?
Ans: 36 electrons. How do you write the electron configuration for krypton? Ans: Krypton electron configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6. What is the electronic configuration of 11na? Step-by-step explanation: When we write the configuration we'll put all 11 electrons in orbitals around the nucleus of the Sodium atom. In writing the electron configuration for sodium the first two electrons will go in the 1s orbital. Therefore the sodium electron configuration will be 1s22s22p63s1.
What is the electronic configuration of N and P?
Answer: Electronic configuration of Nitrogen is 2, 5. Electronic configuration of Phosphorus is 2, 8, 5. Why is group 7 called halogens? Halogen means 'salt-forming compounds'. Group 7 elements when they react with metal forms salt, hence the name halogen.
What is the Colour of each element in Group 7?
| Group 7 element | Colour | Colour in gas state |
|---|---|---|
| Chlorine, Cl 2 | Yellow-green | Yellow-green |
| Bromine, Br 2 | Deep-red | Red-brown |
| Iodine, I 2 | Grey | Purple |
