The element which can not loose electron easily and having electronagtive character is called non-metal it has following property-
1. it can not conduct heat and electricity
2. it is netiher ductile not malleable
3. it is not lsuturous and also not sonorous
Answer:
the first three statement
Explanation:
Its phosphorus (P)In writing the electron configuration for Phosphorus the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for Phosphorous go in the 2s orbital. The next six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the next two electrons in the 3s. Since the 3s if now full we'll move to the 3p where we'll place the remaining three electrons. Therefore the Phosphorus electron configuration will be 1s22s22p63s23p3.
Explanation:
In order to calculate the number of moles of a compound, we will find it out as follows.
No. of moles of chromium(III) chloride =
=
= 0.63 moles
No. of moles of =
=
= 5.88 moles
No. of moles of =
=
= 1.05 moles
No. of moles of =
=
= 1.02 moles
No. of moles of KCl =
=
= 1.34 moles
No. of moles of =
=
= 1.31 moles
No. of moles of =
=
= 6.25 moles
No. of moles of =
=
= 2.27 moles
No. of moles of =
=
= 1.11 moles
Therefore, we can conclude that out of the given options contains the largest number of moles of compound.
