### nebulas:

Emission nebula
* are nebulas.
* e are clouds of dust heated by nearby stars
  - glowing ionized gas
  - high temperature gas
  - fluorescent regions of gas glowing in the presence of embedded stars
  - the nurseries for new star formation
* e are usually isolated regions of much larger interstellar clouds
  - red because they usually produce red light
  - the sites of recent and ongoing star formation
  - make their own light
  - signal the birth of stars and are large
+ Nebula, Types of nebulae, null, Emission nebulae
  * Emission nebulae make their own light. Usually the gases in an emission nebula are ionized. This makes them glow. Emission nebulae are usually red because they usually produce red light.

### nebulas:

Reflection nebula
* Most reflection nebulae are blue because the tiny particles of dust that reflect are very small.
* Some reflection nebulas reflect blue light
* e are a third type of gas-dust cloud found in the interstellar medium
  - also usually sites of star formation
  - blue for the same reason our sky is blue
  - cold un-ionized gas
  - colorful objects
* e are dust clouds that reflect the light of stars nearby
  - which are illuminated by the reflected light of nearby stars
  - visible primarily due to the light they reflect
  - depend heavily on the presence of dust in the cloud
* e reflect the light from nearby stars
  - of a nearby star from their constituent dust grains
  - shine by reflecting light from nearby stars

### negatively charged ion:

Anion
* also is located on a twofold axis.
* are hydrogen atoms, which carry extra electrons
  - larger than cations
  - more attracted to the root surface than cations
  - negative electrons form by the gain of electrons
  - negatively charged electrolytes, and cations are positively charged
  - one of the two types of ions
  - opposed to cations, which carry a positive charge
* have a negative charge
  - negative valence
* is an ion
* migrate to the anode
  - towards the anode, and cations migrate towards the cathode
* move from cathode to anode.
* negatively charged ion.
* vary in ability to enter into complexes.
  * are one of the two types of ions. The other type is called a cation, and these have a positive charge. Ions are atoms that have an electrical charge.

### negatively charged ion | anion:

Hydroxide ion
* are anions.
* has a charge of minus one and it has one potassium.
* is an anion
  - normally a poor leaving group
  - the caustic component of lye, and hydronium ion makes acid solutions corrosive

Negativism
* are quality.
* can be hard for the mate.
* destructive enemy because it gives nothing, expects nothing, and produces nothing.
* greatly limits the potential for creative action.
* is nonproductive and harmful
* often becomes part of their psyche.

Negativity
* Negativities are amounts.
* can slowly erode worker's job satisfaction and performance.
* drains energy, wastes time, and barrier to change.
* exists at the same level in all countries.
* feeds on negativity.
* has a dramatic effect on game play.
* is fueled by anger over having to move
  - infectious, whether it starts on the touch lines or on the field
  - negativity, and it has no place at the helm of a democracy
  - quality
* is the result of faulty thinking
  - unchecked pessimism
  - what campaigning is all about
* key ingredient of proper decision-making.
* much more powerful emotion than being positive.
* naturally dissolves on the half-life principle.
* spreads faster than a cold.
* tends to disagree with or oppose that which is considered positive or constructive.

### neighborhoods:

Urban neighborhood
* Some urban neighborhoods face similar barriers to providing high-quality health care.
* are neighborhoods
  - urban areas
* come in many shapes, configurations, and sizes.
