Slide 1

The Periodic Table Chapter 6

Slide 2

Why is the Periodic Table essential to me? The intermittent table is the most valuable device to a scientist. You get the opportunity to utilize it on each test. It sorts out loads of data about all the known components.

Slide 3

Pre-Periodic Table Chemistry … was a wreck!!! No association of components. Envision heading off to a supermarket with no association!! Hard to discover data. Science didn't bode well.

Slide 4

HOW HIS WORKED… Put components in lines by expanding nuclear weight. Placed components in segments by the way they responded. A few PROBLEMS… He exited clear spaces for what he said were unfamiliar components. (Turned out he was correct!) He broke the example of expanding nuclear weight to keep comparative responding components together. Dmitri Mendeleev: Father of the Table

Slide 5

The Current Periodic Table Mendeleev wasn't too far-removed. Presently the components are placed in columns by expanding ATOMIC NUMBER!! The even columns are called periods and are named from 1 to 7. The vertical sections are called gatherings are marked from 1 to 18.

Slide 6

Groups… Here's Where the Periodic Table Gets Useful!! Components in a similar gathering have comparable substance and physical properties!! (Mendeleev did that intentionally.) Why?? They have a similar number of valence electrons. They will shape similar sorts of particles.

Slide 7

Families on the Periodic Table Columns are likewise assembled into families. Families might be one section, or a few segments set up together. Families have names as opposed to numbers. (Much the same as your family has a typical last name.)

Slide 8

Hydrogen has a place with its very own group. Hydrogen is a diatomic, receptive gas. Hydrogen was included in the blast of the Hindenberg. Hydrogen is promising as an option fuel hotspot for cars

Slide 9

Alkali Metals 1 st section on the occasional table (Group 1) excluding hydrogen. Extremely responsive metals, constantly joined with something else in nature (like in salt). Sufficiently delicate to cut with a margarine cut

Slide 10

Alkaline Earth Metals Second section on the occasional table. (Assemble 2) Reactive metals that are constantly joined with nonmetals in nature. A few of these components are critical mineral supplements, (for example, Mg and Ca

Slide 11

Transition Metals Elements in gatherings 3-12 Less responsive harder metals Includes metals utilized as a part of adornments and development. Metals utilized "as metal."

Slide 12

Boron Family Elements in gathering 13 Aluminum metal was once uncommon and costly, not a "dispensable metal."

Slide 13

Carbon Family Elements in gathering 14 Contains components imperative to life and PCs. Carbon is the reason for a whole branch of science. Silicon and Germanium are essential semiconductors.

Slide 14

Nitrogen Family Elements in gathering 15 Nitrogen makes up over ¾ of the climate. Nitrogen and phosphorus are both imperative in living things. The greater part of the world's nitrogen is not accessible to living things. The red stuff on the tip of matches is phosphorus.

Slide 15

Oxygen Family or Chalcogens Elements in gathering 16 Oxygen is essential for breath. Numerous things that stink, contain sulfur (spoiled eggs, garlic, skunks,etc.)

Slide 16

Halogens Elements in gathering 17 Very receptive, unpredictable, diatomic, nonmetals Always discovered joined with other component in nature . Utilized as disinfectants and to fortify teeth.

Slide 17

The Noble Gasses

Slide 18

The Noble Gasses Elements in gathering 18 VERY lifeless, monatomic gasses Used in lit "neon" signs Used in zeppelins to alter the Hindenberg issue. Have a full valence shell.
