B. product
Think about it like this: a company produces products, not coefficients.
Water molecules are made of hydrogen atoms and one oxygen atom.
Hope this helped!
D
Isotopes have the same number of protons so they both have 17 and a different amount of neutrons which is why the mass number is different
Answer:
Lithium
Explanation:
Alkali metals are group of metals which are present in first group of periodic table. As we know atomic number is equal to number of protons contained by a particular element. Therefore, the alkali metals along with there number of protons are listed below;
Alkali Metal Number of Protons
Lithium 3
Sodium 11
Potassium 19
Rubidium 37
Cesium 55
Francium 87
Hence, it is cleared from above table that Lithium is having fewer protons than 10.
It is greater than the total mass of the products
