Lithium is a Group 1 (IA) element containing just a single valence electron (1s22s1). Group 1 elements are called "alkali metals". Lithium is a solid only about half as dense as water. A freshly cut chunk of lithium is silvery, but tarnishes in a minute or so in air to give a grey surface.
The laws were formulated between 1609 to 16l9, and are (as usually stated):
<ul> <li> Planets move around the Sun in <strong>ellipses</strong>, with the Sun at one focus </li> <li> The line connecting the Sun to a planet sweeps <strong>equal areas in equal times. </strong></li> <li> The<strong> square</strong> of the orbital period of a planet is proportional to the <strong> cube</strong> (3rd power) of the mean distance from the Sun in (or in other words--of the"semi-major axis" of the ellipse, half the sum of smallest and greatest distance from the Sun) </li> </ul> <ol> </ol> <!--more--> <a href="http://www-spof.gsfc.nasa.gov/stargaze/Kep3laws.htm" target="_blank" rel="noopener noreferrer">Read more . . .</a><br />
This high-school level tutorial focuses on three topics: Astronomy of the Earth's motion in space, which includes information, and some experiments and projects that teach concepts about the calendar, seasons, Kepler's laws, building a sundial, and more; Newtonian mechanics, which ha understanding Newton's laws and discussion of mass and motion; and Spaceflight and Spacecraft.

Boolean logic consists of three logical operators:
OR, AND, NOT
OR logic collates the results to retrieve all the unique records containing one term, the other, or both. The more terms or concepts we combine in a search with OR logic, the more records we will retrieve
The more terms or concepts we combine in a search with AND logic, the fewer records we will retrieve.
A few Internet search engines make use of the proximity operator NEAR. A proximity operator determines the closeness of terms within the text of a source document. NEAR is a restrictive AND. The closeness of the search terms is determined by the particular search engine. Google defaults to proximity searching by default.
NOT logic excludes records from your search results. Be careful when you use NOT: the term you do want may be present in an important way in documents that also contain the word you wish to avoid.
