Please do it ( homework )
2. (a) What is the name of the element that has an atomic number of 35? (b) One isotope of this element has a mass number of 79. Write the symbol of this isotope. (c) How many protons, neutrons and electrons are contained in an atom of this isotope (d) Naturally occurring argon consists of three isotopes whose exact masses and abundances are shown in the table below: Isotope Exact Mass Abundance 36 35.9676 0.34 37.9627 18Ar 0.07 39.9624. 99.59 the atomic mass of argon rounded to two places to the right of the decimal point.
