Consider the table below, which shows data from the first six elements of the periodic table. Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus. frederic bartlett teorias

"Witryna10 kwi 2024 · It is denoted by the symbol "A". The mass number determines the isotopic identity of an element, as isotopes of the same element have the same atomic number but different mass numbers. To summarize, the main difference between atomic number and mass number is that the atomic number is the number of protons in the nucleus, … " - Is the atomic mass on the top or bottom

WitrynaThe decimal 22.990 indicates that there are multiple isotopes of sodium, each with a different number of neutrons. However, the isotope with a mass of 23 is the most common by far, so the weighted average of all the sodium isotopes is very close to 23. Thus, the atomic mass is rounded to the nearest whole number, 23. Witryna13 lut 2014 · Feb 13, 2014 Atomic masses increase from left to right and from top to bottom of the Periodic Table. Explanation: As you go from left to right in the Periodic Table, you are adding more protons and neutrons to the nuclei. The atoms in the rows further down have even more protons and nucleons.
