In this image of the periodic table, the LEAST reactive elements are found:
In this image of the periodic table, the LEAST reactive elements are found:
The elements on the right side of the periodic table have more electrons in the outermost ring of their electron clouds, therefore they are less reactive.

The number 10 on this image of the element, Neon, represents:
The number 10 on this image of the element, Neon, represents:
The answer is the number of protons and the atomic number. The number of protons will always equal the atomic number, but the atomic mass is the number of protons plus the number of neutrons, which we cannot see in this image.

What is the atomic mass of the element in this image?
What is the atomic mass of the element in this image?
The answer is none of these. The number on this image is the atomic number, or the number of protons. The atomic mass of this element is not listed, but is calculated by adding the mass of the protons plus the mass of the neutrons, so none of the other answer choices are plausible.

What is an appropriate estimate of the atomic mass of Neon?
What is an appropriate estimate of the atomic mass of Neon?
The answer is 20 amu. The atomic mass of an element is equal to the mass of all the protons plus the mass of all the neutrons. Most of the elements on the periodic table have about the same number of protons and neutrons, which both have a mass of 1 amu. Because we know the atomic number, 10, is equal to the number of protons, we can make a reasonable assumption that the atomic mass of Neon is close to 20 atomic mass units.

Based on the image above, elements in the bottom half of the periodic table have:
Based on the image above, elements in the bottom half of the periodic table have:
The elements at the bottom of the periodic table have higher atomic masses. The atomic mass is determined by the number of protons and neutrons because electrons have an atomic mass of 0 amu.

The elements in the 1st column on the periodic table from Hydrogen down to Francium are:
The elements in the 1st column on the periodic table from Hydrogen down to Francium are:
The answer is "called the Alkali Metals and are very reactive." These elements are on the left side of the periodic table because they are highly reactive metals with a few free electrons in their orbitals. Elements with free electrons have a tendency to share electrons and combine with other elements easily.
