Answer:
When calcium reacts with tellurium it will donates its two electrons and these two electron will be accepted by tellurium.
There must be 1 calcium atom for every 1 tellurium atom in the reaction.
Explanation:
Calcium has atomic number of 20. Its electronic configuration is given as:
![[Ca]=1s^2 2s^2 2p^6 3s^2 3p^6 4s^2](https://tex.z-dn.net/?f=%5BCa%5D%3D1s%5E2%202s%5E2%202p%5E6%203s%5E2%203p%5E6%204s%5E2)
Calcium atom will loose 2 elections to attain electronic configuration of noble gas.
![[Ca^{2+}]=1s^2 2s^2 2p^6 3s^2 3p^6 4s^0](https://tex.z-dn.net/?f=%5BCa%5E%7B2%2B%7D%5D%3D1s%5E2%202s%5E2%202p%5E6%203s%5E2%203p%5E6%204s%5E0)
Tellurium has atomic number of 52. Its electronic configuration is given as:
![[Te]=1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^{10} 4s^24p^6 4d^{10} 5s2 5p4](https://tex.z-dn.net/?f=%5BTe%5D%3D1s%5E2%202s%5E2%202p%5E6%203s%5E2%203p%5E6%204s%5E2%203d%5E%7B10%7D%204s%5E24p%5E6%204d%5E%7B10%7D%205s2%205p4)
Tellurium atom will gain 2 elections to attain electronic configuration of noble gas.
![[Te^{2-}]=1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^{10} 4s^24p^6 4d^{10} 5s2 5p6](https://tex.z-dn.net/?f=%5BTe%5E%7B2-%7D%5D%3D1s%5E2%202s%5E2%202p%5E6%203s%5E2%203p%5E6%204s%5E2%203d%5E%7B10%7D%204s%5E24p%5E6%204d%5E%7B10%7D%205s2%205p6)
So, when calcium reacts with tellurium it will donates its two electrons and these two electron will be accepted by tellurium.
There must be 1 calcium atom for every 1 tellurium atom in the reaction.
B. elements
It's called the periodic table (of the elements)
The compound MnCL2 called
Manganese cloride
Answer:
hi this it for the Instructions: In this engineering lab, you will build and test a device that releases and absorbs
thermal energy in order to reach a goal. You will need to repeat tests of your device to make sure it
does not need to be redesigned or improved. Record your observations and test measurements in
the lab report below. You will submit your completed report. yea that thing the answer is in the file
Explanation:
sorry for telling you on this :( but i hope this helps
Answer:
a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.
Explanation:
A hydrogen bond is a partial intermolecular bonding interaction between a lone pair on an electron rich donor atom, particularly the second-row elements nitrogen, oxygen, or fluorine, and the antibonding molecular orbital of a bond between hydrogen and a more electronegative atom or group.
