1.how are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on the periodic table?2.how does the number of electrons relate to the arrangement what is the different in the number of electrons in a 3rd period element and the 2nd period ...
How do determine the mass number of the element U not the atomic mass? The atomic number of an atom of an element is 17 while its mass number is 35. How many neutrons does the atom have? How do you find the atomic mass of an element?
Atomicity counts the atoms in a molecule, while valency indicates how many bonds an element can form. 12 Can atomicity change for a particular molecule? No, atomicity remains fixed for a specific molecular formula. 9 How does valency relate to electron shells? Valency depends on the number of...
How will the atomic radii change as electrons are added to a shell? How does the periodic table trends for the electronegativity of the elements work? Describe atomic energy levels. How do they relate to the periodic table? Describe how the atomic diameter changes down a...
1) Why is it important to establish a regular schedule?2) What is the purpose of setting clear goals? Why is it important?3) What does “supplementing the work” mean in Paragraph2? Is it necessary to do this in language learning?4) Do you think it is helpful to notice others’ ...
How does lattice energy relate to ionic radii? What is the conductivity of 0.01M KCl? What is the arrangement of ions in a crystal lattice? What is the molecular weight of KCl? What is crystal lattice? Which ionic compound has the greatest lattice energy? 1. MgO. 2. NaBr. 3. LeF. ...
Artwork: From the hair on your head to the t-shirt on your back, everything in the world is made of atoms. I've greatly exaggerated their size in this illustration. On my screen, each of the atomic red dots is about 10 million times bigger than a typical atom. (Your screen may be...
Hope and love are popular themes of literature and art in many human societies. The human physiology of love and hope is less well understood. This review presents evidence that the lack of love and/or hope delays growth disturbs development and maturati
How does the nucleus influence chemical reactions? The nucleus largely determines the chemical properties of an element through its proton count, which defines the element. 4 What is isotopic notation and how does it relate to the nucleus? Isotopic notation provides the proton number (atomic number...
Right multplication of this quaternion then corresponds to various natural operations on this unit tangent vector: Right multiplying by does not affect the location of the tangent vector, but rotates the tangent vector anticlockwise by in the direction of the orthogonal tangent vector , as it ...
