What is the relationship between two element X and Y whose atomic numbers are 18 and 20 but their mass number remains same as 40?
There is no relationship other than having the same mass number. Element X has an atomic number of 18, which makes it the noble gas argon. The particular isotope is argon-40, which means that the atomic nuclei of this isotope of argon contain 18 protons and 22 neutrons. Element Y has an atomic number of 20, which makes it the alkaline earth metal calcium. The particular isotope is calcium-40, which means the atomic nuclei of this isotope of calcium contain 20 protons and 20 neutrons.
What else can I help you with?
What does the term isotope mean?
Isotopes are atoms of the same element that have different numbers of neutrons in their nucleus, resulting in variations in atomic mass. This leads to isotopes having similar chemical properties but different physical properties, such as stability and radioactivity.
What states there is a direct relationship between the volume and absolute temperature for a ideal gas?
According to Charles's Law, there is a direct relationship between the volume and absolute temperature of an ideal gas, assuming pressure remains constant. This law states that as temperature increases, the volume of the gas also increases proportionally, and vice versa.
What is a symbiotic relationship in which one orginisim benefits and the other is not harmed?
A common example of this type of relationship is commensalism, where one organism benefits from the association while the other remains unaffected. An example is the relationship between barnacles and whales, where barnacles attach themselves to whales to gain a stable surface for attachment, while the whales are not affected.
What fraction of the radioisotope remains in the body after one day?
If an isotope is absorbed into the body, the fraction that remains after one day depends on the radiological half-life of the isotope and the biological half-life (basically how fast the element can be eliminated from the body) of the element that the isotope represents.
How long will it take a g sample of bismuth to decay such that 2.0 g of the element remains?
You forgot to say that isotope is.
What is a constant interval?
An interval that remains the same throughout a sequence
What relationship does boyle's law describe?
The relationship between pressure and volume (apex)
What is a static relationship in sciene?
A static relationship in science refers to a relationship between variables where there is a constant or unchanging association between them. This means that as one variable changes, the other remains consistent. It is often represented by a straight line on a graph.
Do banks reuse account numbers?
No, banks do not typically reuse account numbers. Each customer is usually assigned a unique account number that remains theirs for the duration of their banking relationship.
What is the relationship between the temperatuer and the volume of a gas?
As temperature increases so does volume as long as pressure remains constant.
What is the Mathematical relationship between electrical power and the number of coils of wire?
There is none. There is a relationship between voltage and current and turns ratios in a transformer. But this rule remains - power in = power out. You don't get anything for free.
What is the type of relationship between acceleration and force?
The relationship between acceleration and force is direct and proportional. This means that an increase in force applied to an object will result in a corresponding increase in acceleration, assuming the mass of the object remains constant.
Does the relationship between the angle of incidence and the angle of reflection change as the angle of incidence increases?
No, the relationship between the angle of incidence and the angle of reflection remains the same regardless of the angle of incidence. This relationship is governed by the law of reflection, which states that the angle of incidence is equal to the angle of reflection.
How do you calculate the constant of proportionality?
The constant of proportionality can be calculated by dividing the output variable by the input variable in a proportional relationship. It represents the ratio between the input and output quantities in the relationship. This constant remains the same throughout the relationship.
How can a scatter plot be used?
A scatter plot can be used to see if there is any relationship between two variables. It can also give a general idea of the nature of that relationship (linear, quadratic, logarithmic, inverse square, etc; whether or not the relationship remains constant over the domain, whether or not the variation remains constant (homoscedasticity), and so on.
What is the relationship between internal energy and temperature in an isothermal process?
In an isothermal process, the internal energy of a system remains constant because the temperature does not change. This means that the relationship between internal energy and temperature is that they are directly proportional in an isothermal process.
What remains a vital element in crime detection?
The most vital element in crime detection and criminal investigation is the human element.
