this chart shows characteristics of three different types of atoms. which statement is best supported by the information in the chart?
Answers
Answer:
Atom X will accept electrons from atom Y
Explanation:
The outermost shell of an atom is full when it contains 8 valence electrons (except for the first shell, which only contains 2 electrons). Therefore, any atom tends to accept electrons if it's very close to complete the shell with 8 electrons, or to donate electrons if it has only a few electrons in its outest shell.
In this case, we have:
- Atom X: 6 valence electrons --> it tends to accept electrons, since it needs only 2 of them to complete the shell
- Atom Y: 2 valence electrons --> it tends to donate electrons, so it has its outermost shell completed also
- Atom Z: 8 valence electrons --> it has no tendency in donate/accept electrons, since its outermost shell is already full
Therefore, atom Y will donate its 2 valence electrons to atom X, so that both of them have their outermost shell completed.

2.Chemical Energy - is really a form of potential energy and is the energy stored in food, gasoline or chemical combinations.
Examples: Striking a match, combining vinegar and baking soda to form CO2 Gas, breaking light sticks releases chemical energy.
3.Radiant Energy - is a combination of heat and light energy. Light energy, like sound energy, travels out in all directions in waves.
Examples: A light bulb, the glowing coils on a toaster, the sun, and even headlights on cars.
4.Mechanical Energy - is moving energy. It is the form that we most see around us. All moving objects produce mechanical energy. The movements within machines is also mechanical energy.
Examples: People, a rolling bicycle, moving gears, and running cars.
5.Atomic Energy - is produced when you split atoms. A tremendous amount of energy is released when this happens.
Examples:Atomic bombs, nuclear power plants, nuclear submarines, and the sun.
6.Electrical Energy - Energy produced by electrons moving through a substance is known as electrical energy. We mostly see electric energy in batteries and from the outlets in our homes. Electrical energy lights our homes, run motors, and makers our TVs and radios work.
Examples: CD players, TVs and Video games.
Final answer:
The six forms of energy are chemical, thermal, nuclear, electrical, mechanical, and light energy. Each has different characteristics and uses, such as chemical energy being stored in potential changes or light energy being visible to the human eye.
Explanation:
Energy exists in many forms. Here are six common forms of energy:
- Chemical Energy: It is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform into other substances.
- Thermal Energy: It is the internal energy present in a system due to its temperature.
- Nuclear Energy: The energy in the nucleus of an atom. It can be obtained through two methods, namely fission (splitting of atoms) and fusion (joining of atoms).
- Electrical Energy: Form of energy caused by the movement of electrons.
- Mechanical Energy: It's a sum of potential and kinetic energy. It is associated with the motion and position of an object.
- Light Energy: It is a form of energy that is visible to the human eye.

Answer:
the mechanical energy of an object can be the result of its motion (i.e., kinetic energy) and/or the result of its stored energy of position (i.e., potential energy). The total amount of mechanical energy is merely the sum of the potential energy and the kinetic energy.

Explanation
Bone-strengthening activity is key to ensuring that bones remain healthy to maintain an individual's lifestyle. The physical activity to strengthen bone may be brisk walking, exercises that include weights, or gymnastics to lift a few. The purpose of these activities are to observed to contribute to an increase in the bone mineral density of adolescents and children. Several studies have established that about 150 minutes a week for adults, or 3 days a week (60 minutes a day) for the youth should be devoted to bone strengthening physical activity to ensure good health of the body.
Hope this helps!

Answer:
Amplitud = 2 m
wavelength = 35 m
Explanation:
The waves are described by an equation of the form
Y = A sin (kx -wt)
With k = 2 π/λ
With A is the amplitude of the wave, λ the wavelength and w the velocity
If we analyze the reporter's data, the maximum height of the value from zero to the highest, which corresponds to the amplitude of the wave
The other value 35 m between each wave corresponds to the distance between the ridges that is equivalent to the wavelength
35 meters apart makes gives frequency (how many per meter, or how many per 100 meters etc...)
