a positive ion? [Select ]
In which block would you most likely find Element A?
Select)
In which block would you most likely find Element B?
[Select]
Answers
Answer:
the one with the lower ionization energy is more likely to be positive as it is easier to remove the valence electron that causes the positive charge
element a is likely in the s block as that is a low ionization energy and they get larger as you move up and to the R in the table
and element b is likely in the p block for the same reason

The amplitude of a wave is the distance between a point on one wave and the identical point on the next wave T or F?
Answers
It is false that the amplitude of a wave is the distance between a point on one wave and the identical point on the next wave.
What is amplitude?The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position, as defined in physics. It is one-half of the length of the vibration path.
The energy of the disturbance that causes the wave determines the amplitude of the wave. The amplitude of a wave caused by a more energetic disturbance is greater.
A wave's amplitude is the distance from the center line to the top of a crest or the bottom of a trough.
The amplitude of a wave is the height of the wave measured from its highest point to its lowest point. The length of a wave from one peak to the next is referred to as its wavelength.
Thus, the given statement is false, as the definition is of wavelength and not of amplitude.

What is the mass of a boy that weighs 270 N?|
Answers
The mass of boy weighing 270 N has been 27.55 kg.
The mass of the object has been determining the quantity of the matter, while weight of the object has been the mass with the gravitational pull.
The weight of the object has been given as:
Weight = mass × gravitational constant
Weight of boy = 270 N
Gravitational constant = 9.8
The mass of boy is:
270 = mass × 9.8
[tex]\rm Mass\;=\;\dfrac{270}{9.8}[/tex]
Mass = 27.55 kg.
The mass of boy weighing 270 N has been 27.55 kg.

Choose whether each statement is a scientific hypothesis, theory, or law. The pressure a gas exerts on a container increases as the temperature increases because the particles in the warmer gas move faster and collide with the walls of the container with more force.
Answers
Answer:
1) theory
2) law
3) hypothesis
Explanation:
edge 2021
A scientific hypothesis is a proposition that can be determined by experiments. If the gas container is heated, then the pressure inside will increase as shown by the hypothesis.
What is a scientific theory?A scientific theory is a statement that has been tested by a thorough experiment and by following the experimental procedure to evaluate the results. The increase in temperature increases pressure because particle moves rapidly shown in theory.
A scientific law is a statement that is proven true by repeated experiments. As the temperature of the gas increases the pressure also increases showing the law of the ideal gas equation.
Therefore, scientific theory, law, and hypothesis are different.

which element has the highest electrical conductivity (h) (Mg) (CL) (He)
Answers
4. He
Conductivity is the measure of the ease at which an electric charge or heat can pass through a material.A conductor is a material which gives very little resistance to the flow of an electric current or thermal energy.Electrical conductivity tells us how well a material will allow electricity to travel through it.Usually metals are good conductors of electricity.1. Chlorine is a non metal thus it will have the lowest electrical conductivity.
2. As a plasma, helium's electrons and protons are not bound together, resulting in very high electrical conductivity, even when the gas is only partially ionized.
3. Hydrogen is also electrically conductive above certain temperatures.
4. Since, magnesium is a metal thus it is also electrically conductive in nature but less than hydrogen and helium.
Therefore, Helium will have the highest electrical conductivity.

Many physical factors, such as land, climate, and altitude, influence the distribution of natural resources. Because these factors differ from place to place on this planet, the distribution of resources is unequal.
What is earth surface ?The Earth's surface is defined as the part of the water or land that comes into contact with the air above it. The surface is the part of the Earth with which we interact. The crust is the rock layer that surrounds the Earth's mantle. The crust encircles the entire planet, including the ocean floor.
The crust is the planet's surface, where we live; it's actually a very thin layer, only 70 kilometers thick at its thickest point.
Petroleum is formed by the same geological process that creates sedimentary rock. The geological processes that create rocks and natural resources such as granite and copper do not occur everywhere on Earth and take a long time to form. This explains why granite and copper aren't found everywhere on the planet.
Thus, Because these factors differ from place to place on this planet, the distribution of resources is unequal.

1)Which elements are involved in Metallic bonding? ____________
2)How do valence electrons behave in Metallic bonding?_________
3)Provide examples of Metallic bonding in your daily lives. _______
Answers
Answer:
1.) Metals are the only substances that use metallic bonds among their atoms. While many elements are commonly known as metals, including iron, aluminum, gold, silver and nickel, metals include a variety of other elements as well. 2.) In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions.
Explanation:
3.) Metallic bonding is utilized for its conductive properties to help transfer electricity throughout a house via copper wiring.
