What is the most common isotope of potassium?Same Protons, Different Neutrons:The number of protons in the nucleus of an atom determines the atom's element and provides the atomic number to classify the element. However, the number of neutrons in the nucleus of the atom can vary. Each of ...
Mass numbers are used to identify different isotopes of an element and are a count of the protons and neutrons found in that isotope's nucleus. Interestingly, the number of protons will remain constant, regardless of the isotope, but the number of neutrons will change. This is because an at...
Because cases of barium poisoning are accompanied by severe hypokalemia, potassium infusion is an effective antidote. The toxicity of barium compounds depends on their solubility, with the free ion being readily absorbed from gastrointestinal tract or lung, whereas the sulfate is essentially unabsorbed....
How many atoms are in 0.551 g of potassium (K) ? 1 mol K = 39.10 g K 1 mol K = 6.022 x 10 23 atoms K 0.551 g K 1 mol K 39.10 g K x x 6.022 x 10 23 atoms K 1 mol K = 8.49 x 10 21 atoms K 7 Molecular mass (or molecular weight) is the sum of the atomic masse...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
The atomic number of Potassium is 19 and its mass number is 39. The number of neutrons its atom is A19 B39 C20 D58Submit Atomic number of an element is 30 and its atomic are weight is 65. The number of protons and neutrons are A30 and 65 B35 and 30 C35 and 65 D30 and 35Su...
What is the average atomic mass of oxygen? Oxygen: Oxygen is a very important element for animals because it is required for cellular respiration. Plants generate oxygen in the chemical reaction known as photosynthesis. Oxygen is in the second row and sixteenth column on the periodic table. ...
Potassium is most abundant in rock-forming minerals and has an average concentration of 2.09 wt% (Taylor1964) or 400 Bq kg–1(European Commission1999) in the continental crust. Potassium is geochemically an incompatible LILE (large-ion lithophile element), but occurs as a major component in ...
Interpretation: The reason for placement of argon before potassium in spite of its greater atomic mass and theaverage atomic massfor the given elements should be determined. Concept Introduction: Periodic Table:The available chemical elements are arranged considering...
The mass number of an element is 23 and its atomic number is 11 a) Find the number of electrons. b) Find the number of neutrons. c) Write the electronic conf
