An atom of a particular element is traveling at 4.90 % of the speed of light. The de Broglie wavelength is found to be 3.01 fm. What is the identity of the element? Give name or symbol of the element. The speed of the atom was determined to have a variance of
Atoms and Isotopes 1 Activity: Atoms and Isotopes Why? Atoms and isotopes are identified by the numbers of protons, electrons, and neutrons that they contain The number of protons, electrons, and neutrons in atoms determines the chemical properties of the elements .A knowledge of the number of protons and electrons in an atom will help you understand how atoms combine to form molecules Identify the composition of atoms in terms of protons, neutrons, and electrons Use atomic symbols to represent...
26 Which statement is NOT TRUE? (A) Every atom of a given element has the same number of protons. (B) Almost all of the mass of an atom is located in the nucleus. (C) A given chemical species doesn't always have the same type and number of atoms. (D) The large cloud region of the atom contains electrons, which are 50% of the mass of the aton (E) Different isotopes of the same element have different numbers of neutrons.
B) Theories must be testable; hypotheses do not need to be testable. CHypotheses are educated guesses, and theories are tentative explanations. D) Hypotheses are derived from experimentation, whereas theories are derived from observation. 12) A) Water is an example of an element. B Nitrogen C) Glucose D) Salt 13) What are the four most common elements found in living organisms? A) nitrogen, oxygen, phosphorus, and carbon carbon, oxygen, nitrogen, and hydrogen C) carbon, oxygen, potassium, and calcium D) oxygen, calcium,...
4. The ground-state valence-shell configuration of a particular atom is 4f1450'6s2. The element to which this atom belongs is a a) noble gas. b) S-block main-group element. transition element. inner transition element. e) p-block main-group element. d)
(1): Do you expect the mass of 12C and 13C the same? if not, how do we report "average atomic mass" for carbon? what additional information we need to get the average atomic mass for carbon? (1b) If an element has two isotopes, for example 12C, and 13C, list what they have in common and list what they differ.
QUESTION 3 A fictitious element is composed of isotopes A and B with masses of 61.9887 and 64.9846 amu respectively. The average atomic mass of the element is 64.52 amu. What can you conclude about the natural abundances of the two isotopes? O The natural abundance of isotope A must be greater than that of isotope B OThe natural abundance of isotope B must be greater than that of isotope A. O The natural abundances of both isotopes must be...

How can you identify an element/atom can form: a) Ionic bonding b) Covalent bonding c) Hydrophobic bonding What do you need to do to determine if an element/atoms belongs to: a) Group b) Period?
im confused with this question: i thought atoms A and B were isotopes since both of them have the number of protons equal to the number of electrons but different numbers of electrons. I put the book answer picture also that says that none of them are isotopes. i feel like Lana Del Rey meme now ??♀️ b. What is the percent un tium isotope? 5.77 Using the information given in the fion given in the following table ate whether...
