Answer:
Ge only has 2 pair of unpaired electrons.
Explanation:
An oxygen atom is 16x more massive than a hydrogen atom.
You can figure this out by comparing the atomic masses of the two elements: oxygen has an atomic mass number of 16, and hydrogen has an atomic mass number of 1. Thus, an oxygen atom is 16 times more massive than a hydrogen atom.
Answer:
The compound is an <em>alkali</em>
Explanation:
Although acids and bases in solution can conduct electricity due to the presence of free ions available to carry charges, bases or alkalis turn phenolphthalein indicator pink; as opposed to acids which give colourless test on the indicator.
The anayte compound is therefore a concentrated alakli solution.
Answer:
Isotopes of bromine have same chemical properties because they have same number of electrons.
Isotopes have only different number of mass that does not affect it's chemical properties too much.
