Select all the correct images.Select the two atomic models that belong to the same element.
Answers
Answer : The atomic models that belongs to the same element are atomic model 2 and 3. (Shown below)
Explanation :
As we know that an atom is the smallest unit of a matter that consist of three subatomic particles which are electrons, protons and neutrons.
The protons and the neutrons are located inside the nucleus or center of the nucleus where the mass of the an atom is concentrated and the electrons are located around the nucleus.
The protons are positively charged, the electrons are negatively charged and the neutrons are neutral that means it has no charge.
Atomic number is defined as the number of protons or number of electrons.
Atomic number = number of protons = number of electrons
Same element has same number of protons.
Atomic model 1 : In this model, there are 8 number of electrons, 8 number of protons and 8 number of neutrons.
Atomic model 2 : In this model, there are 5 number of electrons, 5 number of protons and 6 number of neutrons.
Atomic model 3 : In this model, there are 5 number of electrons, 5 number of protons and 5 number of neutrons.
Atomic model 4 : In this model, there are 6 number of electrons, 6 number of protons and 6 number of neutrons.
From this we conclude that, the atomic model 2 and 3 has same number of protons. So, these two models belongs to the same element.
Hence, the atomic models that belongs to the same element are atomic model 2 and 3. (Shown below)

What is an ecosystem?
An Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the ecosystem through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Many insulating materials contain spaces filled with air because ; Air is a poor conductor of heat and electricity
Insulators are materials that do not allow the easy passage of heat or electricity through them. they are used to protect users from direct exposure to electricity and heat and also for the protection of equipment's at home and at work places.
Insulators are generally bad conductors of heat and electricity. some examples of insulators are ;
- Dry wood,
- Air,
- Porcelain,
- Rubber,
- Plastic and glass
They are all very good insulators. but the most commonly used insulator in electrical installations is Porcelain
Hence we can conclude that many insulating materials contain spaces filled with air because Air is a poor conductor of heat and electricity.
