Homework Answers
Answer -B . Electrons determine the atoms size .
Electrons remain at the surface of an atom and an atom when come close to one other they started repelling because like charges repel and unlike charges attract . Electrons are negatively charged and protons are positively charged . Two opposite charges attract each other . And anything which occupy space and has mass is known as matter so the statement 3 is also incorrect .

Part A An atom's size is determined by how far the outermost electrons are from the nucleus. The size of an atom is affected by the size of an atom's orbitals as well as by the positive pull of an atom's protons. Arrange the following elements in order of decreasing atomic size. Rank the atoms from the largest to smallest. To rank items as equivalent, overlap them. ► View Available Hint(s) Reset Help Largest atom Smallest atom 1 Review Constant...
