Cellular Respiration and Photosynthesis. Photosynthesis is the process of when plants use sunlight to make foods from carbon dioxide and water, to later on make oxygen. Cellular respiration is the process through which cells convert sugars into energy.
The smallest and the basic particle of a chemical element is said to be an atom. It is made up of three subatomic particles that is electrons, protons and neutrons. The neutrons and protons are present in the nucleus of an atom whereas electrons are present in the orbits around the nucleus of the atom. There are several shells in the orbital depending on the atomic number. The electrons which are present in the outermost shell are said to be valence electrons.
They can be determined by the electronic configuration of the element.
The atomic number of strontium, is 38. The electronic configuration of strontium, is:
From the electronic configuration it is clear that the outermost shell of strontium, is . So, the number of valence electrons in strontium, is 2.
Hence, there are 2 valence electrons in an atom of strontium ().
A. contact list hope it helped you with ur question
Answer:
C6H12O6+6O2->6CO2+6H2O
Explanation:
You need to start in for the given Questions think in a way what will you need a number for fit to the chemical name. I would suggest if you need practice because sometimes it goes higher when you are chemistry student especially involved in fraction. Thank you for listening
10 is c, 6 is d, hope this helps !
