# When six protons and six neutrons unite to form a carbon atom, the net mass of the 12 nucleides decreases? Topic: Homework forms of energy
July 19, 2019 / By Garnette
Question: slightly. This __________ multiplied by _______ equals the nuclear binding energy of arbon 12. A: mass defect, the atom's mass. B: mass difference, mc^2 C: mass defect, mc^2 D: mass difference, the atom's mass If you pass radiation between two charged plates, which two kinds of radiation emissions willbe attracked and bent toward a negative plate? A: Positrons and alpha particles B: Beta particles and gamma rays C: Gamma rays and positrons D: Alpha particles and Beta particles I have done all my homework myself, I am just stuck with these 2 questions, so please no answers telling me to do it myself ## Best Answers: When six protons and six neutrons unite to form a carbon atom, the net mass of the 12 nucleides decreases?

First question: C (except the "m" should not be there since it is the answer for the first blank you filled in). Nuclear binding energy is calculated by multiplying the change in mass (or mass defect) by the speed of light squared. Second question: A Positrons and alpha particles both have a positive charge. These positive charges will be attracted to the negative electric plate and their path will be bent toward the negative plate.

terrible question ******** atoms have a nucleus containing 1 or more protons, 0 to infinite neutrons which is surrounded by a region of electron density. We group "like" atoms into "elements". Atoms are "like" if they have the same number of protons in their nucleus. Look at a periodic table. Starting with H as you move right across the table and start a new row when you reach the far right, you add 1 proton (atomic number by definition is the number of protons) BUT.. the number of neutrons is free to vary example: .. All H atoms have 1 proton so that .. an atom with 1proton and 0 neutrons is an atom of hydrogen .. an atom with 1p and 1n is an atom of hydrogen too! .. an atom with 1p and 2n's is another atom of hydrogen example: .. all He atoms have 2 protons .. 2p + 0n is an atom of He .. 2p + 1n is an atom of He .. 2p + 2n is an atom of He .. 2p + infinite neutrons is an atom of He we differentiate atoms of the same element (i.e. the same number of protons) that have different numbers of neutrons with the term "isotope". Two atoms of the same element with different numbers of neutrons are different isotopes of that element. ******** now many students are confused by the following terms.. So let's cover them. ATOMIC MASS:.. this is the mass of 1 atom. And it depends on which particular isotope you are referring to. Different isotopes of the same element have different atomic masses. And one last thing, atomic mass is the sum of the mass of the parts - "mass defect". google that term. so atomic mass = mass protons + mass neutrons + mass electrons - mass defect. RELATIVE ATOMIC MASS: this is the number shown on a periodic table. it is the average mass of all naturally occurring isotopes of an element weighted by relative abundance. It is an AVERAGE mass. not the mass of any 1 atom!!!! And it does indeed include mass of electrons. MASS NUMBER: this is NOT a mass at all. It is a count of protons + neutrons. it is a whole number. It should really be called "nucleon number". Many students get confused and think "relative atomic mass" and "mass number" are the same thing. they are NOT!!!! MOLAR MASS: This is not the same thing as atomic mass, nor relative atomic mass. atomic mass is the mass of 1 atom. Molar mass is the mass of 6.022x10^23 atoms. ATOMIC NUMBER: Also shown on a periodic table. this is the number of protons in any atom of that element by definition. ******** silicon... from this periodic table http://ptable.com/ atomic mass Si = # protons in any atom of Si = 14 relative atomic mass = 28.04.. this is the weighted AVERAGE atomic mass of all naturally occurring atoms of Si.. not the mass of any particular atom from this table http://en.wikipedia.org/wiki/Isotopes_of... atoms of silicon with 8 to 30 neutrons have been isolated in the labs. You can see the mass number (sum of protons + neutrons) in the "nuclide symbol" column. You can see the "atomic mass" of each of atoms of each of those isotopes in the "isotopic mass" column. Z is the number of protons... the atomic number of silicon the relative atomic mass is the weighted average mass of Si-28, Si-29, and Si-30.. the 3 stable isotopes *********** so.. to answer your question .. (1).. atomic mass depends on the isotope .. (2).. relative atomic mass = 28.04 .. (3).. # protons = 14 .. (4).. # neutrons = 0 to infinity .. (5).. # electrons > 0... (atoms aren't necessarily neutral) the most common atom of Si has 14p, 14n, 14e, atomic mass = 27.98 amu/atom ****** any of this sinking in?

Mass is defined in terms of inertia - the need for a force to make something change its direction or speed of motion. Mass and energy are under some circumstances interconvertible, as expressed in the equation E = mc^2 but a lot of conditions have to be satisfied for this to happen large scale. For example, you can't turn an electron into pure energy, but an electron and the positron will react to generate energy in the form of a pair of gamma rays (challenge problem for readers: why do you need TWO gamma rays, not just one?). The reference to Higgs was spot-on. This is all very much physics. No one really knows, but we haven't given up and shouldn't give up of finding out quite a bit more. BTW, a neutron weighs slightly more than a proton, and roughly 2000 times as much as an electron. You can calculate the energy released in a nuclear reaction by subtracting the mass of the products from the mass of the parent, and using Einstein's formula. The mass of a proton involves the mass of the quarks, of the gluons holding the quarks together, and the energy involved.

The atom is Silicon. The atomic mass is 14, which means it has 14 protons and 14 electrons. The amount of neutron depends on the atomic weight, which in this case is 28.086 or rounded to 28.1. 28.1-14 means the amount of neutron is also 14.. Britannia
I'm going to go with C for the first one, but do yourself a favor and look it up here, cause im not sure myself ...http://en.wikipedia.org/wiki/Mass_differ... The second question the answer is which particles are positively charged. If you cross out the photon radiation, the neutral particles and the negatively charged particles you should end up with just the ones you need. thats Positrons and alpha particles. so A is your answer.
