Which element does X represent in the following expression: EX? Enter the chemical symbol of the element:
students welcome here in this question we have an X element is given. So it is represented as X jewel and 25 is a given. Okay, so this one is Z is equal to 12. So the number of protons, it represents the number of protons and number of electrons. Okay, so 12 represents the number of protons and number of neutrons number of electrons and Ze. Yeah, so this one is atomic mass. 25 represents the mass number atomic mass number. And here the number of neutrons, this is equal to 25. Well that is equal to 13 neutrons are present here. Okay, so now we have to represent the element expertise. The element X represents. We know that the atomic mass of an element which is having 12 is magnesium. So magnesium is the element which is having atomic number 12 and mask number Can be 25. Okay, so here the element can be represented Mac MZ 12 and 25. So this is the magnification representation of the given element X. Okay, thank you.

What element does this number 25-12 stand for?
As a transition metal, manganese, a chemical element with the symbol Mn and atomic number 25, is a solid at room temperature.
Which two of the following—3116X, 3115X, and 3216X—are isotopes of the same element?
A: (a) The isotopes of the same element are 31 16X and 3216X.
Which of the following has chemical properties in common with the others: allotropes, isotopes, isotones, and isobars?
Isotopes have similar chemical properties because they share the same electronic configuration and atomic number, so the correct response is option A. Isotopes.
What three isotopes are examples?
Carbon-14, tritium (hydrogen-3), chlorine-36, uranium-235, and uranium-238 are a few examples of radioactive isotopes.
What are isotopes and isotones? What is the Class 12 example?
When two nuclides have the same neutron number N but different proton number Z, they are said to be isotones. For instance, boron-12 and carbon-13 nuclei both have 7 neutrons, making them isotones. Likewise, 36S, 37Cl, 38Ar, 39K, and 40Ca nuclei all have 20 neutrons, making them all isotones of 20.
Give two examples of each for isotopes and isobars.
Iron and nickel, which both have the same mass number of 58 but different atomic numbers of 26 for iron and 28 for nickel, are an example of two isotopes and isobars.
Describe isotopes and give two examples.
Three isotopes of carbon, carbon-12, carbon-13, and carbon-14, each have six protons, but six, seven, and eight neutrons, respectively.
What does Value Class 9 mean?
For example, the valency of sodium (Na) is 1, magnesium (Mg) is 2, chlorine (Cl) is 1, etc. Valency is simply the number of electrons gained, lost, or shared by an atom of an element to achieve the closest noble gas configuration.
Which 3 isotopes are there?
There are three isotopes of the element hydrogen: hydrogen, deuterium, and tritium. How do we distinguish between them? They each have a single proton (Z = 1), but they differ in the number of neutrons in their nuclei.
