Basic Facts Of Metals and Nonmetals

Fashioned For You

Elements can be divided into two classes:
1)Metals
2)Non Metals

Properties Of Metals:
1) Have lusture
2) Opaque - Liquid cannot pass through
3) Hard
4) Strong
5) Hard wearing, last long
6) Malleable - Can be hammered into shapes
7) Ductile - Can be drawn into wires
8) Good conductor of electricity and heat

Short terms of elements:
1) Meth
2) Eth
3) Prop
4) But
5) Pent
6) Hex
7) Hept
8) Oct
9) Non
10) Dec

Second part of SCI 10

1) Is a good conductor of electricity
2) Sonorous - produce ringing sound when hit
3) Usually solid at room temperature
4) High density - usually heavy
5) Form basic oxides
6) high melting point
7) Ions of metals have positive charges

Exceptions:
Sodium is a soft metal of low density

Properties of Nonmetals:

1) Dull - Not shiny
2) Soft
3) Brittle - Breaks easily
4) low density - light
5) poor or non conductor of heat and electricity
6) usually liquids or gasses
7) low melting point
8) form acidic oxide
9) some ions have negative ions other are neutral


Oxide is a binary compound of oxygen and another element or group.

Reproduction

What is asexual reproduction?

Asexual reproduction is the process where only one parent is needed to create offspring through budding, grafting, fission, binary fission, spore formation and fragmentation.  

How it happens?

Asexual reproduction occurs through one of the processes that are budding, grafting, fission, binary fission, spore formation or fragmentation. Any of those processes can occur but it depends of the circumstances that the organism is in.

What are the different types of asexual reproduction in plants and animals?

What are the benefits of asexual reproduction for plants and animals?

The benefits are that only one organism is needed to create offspring and this is good because finding a mate can be difficult for some organisms that are in desolate environments. Another benefit is if an organism is in a dire situation then it can clone another organism to pollinate if there no other pollinators.
