The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Therefore, we group elements whose atoms have the same number of valence electrons together in the Periodic Table. ... This tendency is called the octet rule, because the bonded atoms share eight valence electrons.
pH of 1 is Red
pH of 13 is Yellow
Explanation:
Indicators are substances which change color to signal the end of an acid-base reaction as required by the balanced chemical equation of the reaction.
Examples are:
- methyl orange
- methyl red
- phenolphthalein
- litmus
- cresol red
- cresol green
- alizarin R3
For methyl red:
pH 1 is acidic and its red
pH 13 is basic and it is yellow
pH 7 is neutral and it is orange

Answer: stars vary in their effective temperature and colour. A hot star radiates more energy per second per metre surface area than a cooler star. Does this then mean that a hot star is going to appear brighter to us than a cooler one? The answer to this actually depends on a few factors
