two types of waves
Transverse Wave and Longitudinal waves
Which element is an example of transparent material_

Sodium +________=Sodium Chloride
Chloride
How do the elements group 7 look
A pale of colours
what kind of animals live on the jungle
Mammals, Birds, Reptiles, Amphibians, insects
in which wave a radio is?
Transverse wave
How makes the camera refraction posible
it travel trought the lens of the camera
magnesium+oxygen=______________
Magnesium Oxide
Is the group 7 reactive? Why?
Yes, because Halogens are highly reactives because they have 7 electrons in their outermost shelf
Why do animals live in groups?
Therefore, species that form groups through social interaction will result in a group of individuals that gain an evolutionary advantage, such as increased protection against predators, access to potential mates, increased foraging efficiency and the access to social information.
What is the sound?
vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.
Why is refraction important to a camera?
If you want to create an image you need to be able to focus all of the incoming rays into a single point
Silver Lodine
Explain the reactivity of group 1
They have no tendency to lose, gain or share electrons
What is animal adaptation?
An adaptation is defined as a physical or behavioral feature of an animal that helps them better survive in their environment
Does sound travel faster in space?
Sound does not travel at all in space
Hou does light allow us to see colour
cone cells help detect colours
The reaction between silver and iodine
Silver+Lodine=Silver Lodile
Why is it called a periodic table?
It is called the periodic table because of the way the elements are arranged.
Do humans have adaptations?
Because of these adaptations, and because of many environmental factors, humans have also adapted biologically throughout human history
Can sound waves generate heat?
Yes, sound can generate heat
why the rainbow appear?
Because the sunlight look like white light and the rain, when the sunlight enters a raindrop the different colours aare hent a different anngles
The reaction between two elements to produce carbon dioxide
Carbon+Oxygen= Carbon Dioxide
What is an atom? What are atoms made of?
Atoms are the basic particles of the chemical elements. An atom consists of a nucleus of protons and generally neutrons, surrounded by an electromagnetically bound swarm of electrons
