The atomic number,atomic mass,valence electrons and the formula for calculating the number of neutrons is also given.The following table has been completed below in the attachment.

Explanation:

Atomic Number:the number of protons /electrons present in the nucleus of an atom is called the atomic number.

Mass Number/Atomic Mass:the number of protons and neutrons present in a nucleus

<u>Example:</u>C_{6} ^{12};here;6 implies the atomic number and 12 implies the mass number/atomic mass

<u><em>No.of neutrons=Mass number-Number of protons</em></u>

Valence electrons:the number of electrons present in the outer most shell of an atom are called valence electrons

<u>Example:</u>If we consider a carbon atom;as its <em>e</em><em>lectronic configuration is2,4 and</em>  it belongs to 4th group.Therefore the number of valency electrons in carbon is <u>4.</u>

A 133.8-gram sample of bronze was 10.3% tin by mass. Determine the total mass of tin in the sample.
Kay [80]
You just need to multiply the total mass by the decimal value of the part that is tin. 133.8*0.103=13.8g (following the rules of significant figures).
