Mass number is the total count of both protons and neutrons in an atom. This is helpful when identifying different isotopes of an element. While the number of protons remains the same for all isotopes, otherwise the atom would change elements to one with a matching number of protons, the ne...
In an ocean that is rapidly warming and losing oxygen, accurate forecasting of species’ responses must consider how this environmental change affects fundamental aspects of their physiology. Here, we develop an absolute metabolic index (ΦA) that quantifies how ocean temperature, dissolved oxygen an...
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 so-calledbody mass index(BMI) refers to a formula for estimating the extent to which one is under- or overweight. The higher the number, the more one’s score moves from being skinny to being obese. Typically, BMI scores in the 18–25 range are considered normal, while 25–30 are...
aGiven the atom and mass ratios of X to oxygen, you need to figure out the mass of X that combines with 47.998 u O, i.e., the mass of three O atoms. At this point you divide by 2 and the result should appear some place in the periodic table! 假使X原子和大量比率氧气,您需要...
What is the mass number of gold? How much atomic mass does bohrium have? What is the mass number of an oxygen atom with 7 neutrons? What is lawrencium's atomic mass? What is the mass of carbon in 58.5 grams of NaC7H5O2?
All the atoms of a particular element have the same number of protons, and hence the same atomic number. Atoms of different elements have different atomic numbers. For example, all carbon atoms have the atomic number of 6, whereas all atoms of Oxygen have 8 protons in their nucleus. What ...
