Lithium 6 would have 6 valence electrons in the outer orbital, while lithium 7 would have 7 in the outer orbital.
Answer: 10 electrons
Explanation:
N represents Nitrogen. Nitrogen has an atomic number of 7, this means in ground state it has 7 electrons also.
But N-3, means Nitrogen has gained 3 more electrons. So, we have 10 electrons
Answer: Ionic bond is composed of Ca2+ cations and Cl– anions; those ions are stable since they have filled valence shells. Its ionic formula is written as CaCl2, the neutral combination of these ions.
Explanation:
Answer:
<h3>A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. A chemical property describes the ability of a substance to undergo a specific chemical change.</h3>
Explanation:
<h3>Physical properties can be broken down into extensive and intensive properties. Intensive properities can help you identify a substance. ... Other examples of intensive properties include density , solubility, color, luster, freezing point and malleability</h3>
<h3>Luster. ... Luster is how the surface of a mineral reflects light. It is not the same thing as color, so it crucial to distinguish luster from color. For example, a mineral described as “shiny yellow” is being described in terms of luster (“shiny”) and color (“yellow”), which are two different physical properties.</h3>
