Explanation:
Answer:
Its either glucose or protien
Explanation:
The atomic cation with +1 charge with the following configuration:
1s22s22p63s23p6
Is Potassium (K+), remember potassium have 19 electrons in its neutral state, when if losses one electrons it becomes + with one less electron, meaning it will have 18 electrons as a cation.
There are 2 electrons in 1s orbital as it can be seen from the electron configuration.
Answer:
P4 + 5O2 --> 2P2O5
2C2H6 + 7O2 --> 4CO2 + 6H2O
Explanation:
As against non-metals are the elements which are usually soft. ... Generally, the elements containing 1,2 or 3 electrons in the valence shell of their structure are known as metals. While the elements with 4, 5, 6 or 7 electrons in their outermost shell are known as non-metals.
