Problem 48E

Which statements about subatomic particles are false?

a.        Protons and electrons have charges of the same magnitude but opposite signs.

b.        Protons have about the same mass as neutrons.

c.        Some atoms don't have any protons.

d.        Protons and neutrons have charges of the same magnitude but opposite signs.

Step-by-Step Solution:
Step 1 of 3

Solution : In chemistry, the empirical formula of a chemical compound is the simplest positive integer ratio of atoms present in a compound. The smallest whole number ratios of the subscripts of molecular formula are derived by dividing the subscripts by largest common factor. For example: the mpirical formula of disulfur dioxide is S O . 2 2 the e mpirica l formula of ethane(C H 2 w6l be CH . 3 Empirical formula gives the relative numb er of atoms of each kind present in that compound. For example: Consider, Ethane (C H 2 6 Relative number of atoms in simplest form will be CH and it is the3empirical formula of ethane. Molecular formula is a chemical formula that gives the total number of atoms of each element in each molecule of a substance. These definite numbers of atoms present in a molecule are repre sented as s ubscripts in the molecular formula. For Example : C H is the molecular formula of ethane. 1 molecule of ethane contains 2 2 6 atoms of Carbon a nd 6 hydrogen (H) atoms. Now, let’s see if 2 compounds have same empirical formula and molecular formula, if they are the same compound: Let’s consider a scenario : There are some compounds which have same molecular formula and empirical formula. In these compounds, the subscripts in molecular formula will be already the smallest whole number ratios which cannot be divided further by largest common factor. For example: Consider,...
