Want this question answered?
i dont no
Learn that the atomic number means the number of protons. The mass number is the number of protons and the number of neutrons. So if we take the number of protons from the mass number then we get the number of neutrons that are present (mass umber - atomic number = number of neutrons). in this case 15 - 8 = 7. Since you dont mention there is any charge on the atom ill assume that its charge is neutral. For an atoms charge to be neutral then the positive charges from protons must equal the negative charges from electrons and vica versa. So for this to be the case with 8 protons then we must have 8 electrons.
Magnesium is a metal element. There are 12 electrons in a single atom.
The number of protons determines the name of the element: 5 Protons = Boron (B) (just look at the periodic table and the atomic number corresponds to the number of protons the element has)The atomic mass of the element determines the isotope of the atom which is simply Protons (5) + Neutrons (6) = atomic mass (11) so the isotope of this Boron atom is written as 11B (this is short hand the more formal version is written with the atomic number written right below the atomic mass, but i dont know how to do that on the computer)Now the last thing is the charge which is Protons (5) - Electrons (2) = Charge (3+) you subtract the number of electrons because electron's charge is negative one) so the final answer will look like this 11B3+
dont now
well the electrons must be researched and the atomic number and since the protons are equal to the electrons you dont have to go crazy looking for it.i dont know how to find the atomic mass though
The atomic number of the potassium is 19. So the number of protons and electrons is 19 in the atom of potassium. The number of neutrons can be calculated as mass number minus atomic number. It comes to be 39 minus 19. That is 20.
protons dont have an atomic number as they are not elements
you dont count you measure it
For a neutral atom they must have equal numbers of protons and electrons. The atomic number is the number of protons in an atom of an element. Find the atomic number by looking at the periodic table of elements.
i dont know dont care dont count on it.
you go to Everybodys House and count how many people live in that particular House. and Dont forget to count the hobos, they count to you know even If they dont live in a house.
i dont know its symbol it might be pu but the atomic # is 94 and the atomic mass is 244 i dont know its symbol it might be pu but the atomic # is 94 and the atomic mass is 244
dont know why dont you go count them!
for a fact it is heat or electrons dont belive me go to quizlet and ask them if you dont belivr me!
dont allowed to count
i dont know, i hate chemistry it sucks! i wanna no 'if an element has 17 protons, how many electrons are there?' sorry i didnt no the answer
