The atomic mass number of each element appears under its symbol in the periodic table. It's listed in atomic mass units, which is equivalent to grams/mole.
atomic mass c. atomic number d. neutronsHow do you find the number of valence electrons of an element?1. How many elements are on the periodic table? 2. Which of those are: a. metal? b. gas? c. unknown?What are the representative elements? In what region(s) of t...
3\. Below the symbol is the atomic mass. While this number is a weighted average of the masses of all isotopes of the element, if you round the number to the nearest whole number you will find the mass number of the most common isotope. For carbon the mass number (M) is 12. This ...
If you know the atomic number and the mass number of an isotope of an element, how can you determine the number of protons and neutrons?Answer and Explanation: The atomic number is equal to the number of protons in an atom. F...
How to get the selected items of a ListView in TextBox or Msgbox I select multiple items using CTRL key.Please see picture below : Where I selected 3 items and I need to get the selected Items in a TxtBox, or Msgbox.Thanks in advance !
Use the periodic table to determine theatomic massof each element in the molecule. Multiply each element'satomic massby the number of atoms of that element in the molecule. This number is represented by the subscript next to the element symbol in themolecular formula. ...
The quickest way to find the factors of a number is to divide it by the smallest prime number (bigger than 1) that goes into it evenly with no remainder. Continue this process with each number you get, until you reach 1. Prime Numbers ...
Question: QUESTION 6 Identify how the atomic mass of an element is determined. average mass of all ions average mass of the isotopes that compose that element average mass of only the radioactive particles average mass of the electrons in that elem...
Find the relative mass of any atom by adding the number of protons to the number of neutrons. Hydrogen has a relative atomic mass of 1, and carbon-12 has a relative atomic mass of 12. Isotopes of the same element have different numbers of neutrons, so you need to calculate for one spe...
c. atomic mass number Atomic Number: The atomic number of an element represents the number of electrons or the number of protons in the element while the atomic mass represents the sum of neutrons and protons that exist in the element. ...
