Question

directions: use the terms below to complete the following paragraphs about atoms, atomic mass, and isotopes. terms may be used more than once.
six neutron(s) proton(s) mass isotopes quarks electron cloud
electrons six protons
the electron has very little mass compared to the 1.____ or 2.__. the mass of the atom depends on the nucleus and how many 3.__ and 4.__ it has. the sum of the protons and neutrons is the mass 5.__. the number of neutrons in an atom can be found by subtracting the atomic number from the 6.__. the mass of the atom is so small that there is a measure called the atomic 7.____ unit designated by amu.
8.____ and 9.__ make up the nucleus and are made up of 10.__. there are 11.____ quarks uniquely
of 12.____. the nuclei of all atoms of a given element always have the same number of 13.__. they will also have the same number of 14.__. some atoms may have more or fewer 15.__ than will other atoms of the same element. atoms of the same element with different numbers of neutrons are called 17.__. every atom of carbon must contain 18.____. but some contain six neutrons and others have eight neutrons.

Explanation:

The problem is about filling in the blanks related to atomic structure. The electron has little mass compared to protons or neutrons. The mass of the atom depends on protons and neutrons. The mass number is the sum of protons and neutrons. Subtracting atomic number from mass number gives neutrons. The atomic mass unit (amu) is for measuring atomic mass. Protons and neutrons are made of quarks. Electrons are in the electron cloud. Isotopes are atoms of the same element with different neutrons. Carbon atoms must have six protons.
