Neutron - The neutron is a subatomic particle with no net electric charge and a mass slightly larger than that of a proton. Neutrons are usually found in atomic nuclei. The nuclei of most atoms consist of protons and neutrons, which are therefore collectively referred to as nucleons. The number..
Neutron number - The neutron number, symbol N, is the number of neutron s in a nuclide. Atomic number ( proton number) plus neutron number equals mass number: Z+ N= A. Neutron number is rarely written explicitly in nuclide symbol notation, but appears as a subscript to the right of the element..

Multiplication of a matrix by a scalar
Let A=[a i j ] be an m x n matrix and k be any number called a scalar. Then the matrix obtained by multiplying every element of A by k is called the scalar multiple of A by k and is denoted by kA. Thus, kA = [k a i j ] m x n..

Assume the validity of the result for n equal to some arbitrary but fixed natural number, say, k..
Suggested answer:
= (14 - 12) - (7 - 3) + (4 - 2) = 2 - 4 + 2 = 0 The system may have infinite number of solutions or no solution. Put x = k in (1) and (2) and solve y + z = 6 - k 2y + 3z = 14 - k. Solving the above two equations, we have z = k + 2 and y = 4 -..

How I can Demonstrate the atomic mass is approximately equal the number of protons + the number of neutrons ?I also presume for the sake of my presentation that matter in general will increase in mass by the same factor that Mr Haramein increased the mass of the proton. 3) The Necessity of Changing the value for the Gravitational Constant, when the Value for the mass of the proton, implying the mass of matter in general, is changed. The gravitation constant was calculated using the standard unit of mass. According to the laws of Algebra, if you change the standard unit of mass, then you need to ...
Question : A plot of the number of neutrons versus the number of protons in nuclei shows a narrow band of stable isotopes. Elements below this narrow line may attain stability by
a.beta emission.
b.alpha particle capture.
c.neutron emission.
d.electron capture.
e.gamma ray emission.
Answer : Below the band of stability, the ratio of the number of protons of the element to the number of neutrons of the element is greater than 1. In other words, the number of protons of the element is greater than the number of neutrons of the element. Therefore, it should decrease its number of protons and increase its number of neutrons to gain stability by entering the stability zone (band of stability). This is achieved by two types of radiation (decay). One of them is giving in your question: Electron Capture. Because in electron capture; one of the electrons in K-shell is attracted by the nucleus where it is combine with a proton and creates a neutron. (1 and 1) p + (-1 and 0) e -------> (0 and 1) n The first figure in parenthesis represents the charge and the second figure represents the mass in nuclear symbols) This process decreases the number of protons and increases the number of neutrons. Mass number of the element does not change, but its atomic number decreases by ..

Question : My Daughter had her tongue pierced yesterday. Is doing o.k. but compkains of a strange sensation on the tip of her tongue. Says it feels like it tingles...has feeling but not so much. She is of course swollen.
The piercers aren't open again till Tuesday.
Is this a possible reaction? Doesnnormal sensation return after the swelling subsides? 1st off, thanks so far for the reassurance on the tingling...
2nd....do any of you with the smart ass remarks even have a clue how old she is? A decent par..
Answer : personally that sounds normal I had 2 tongue piercings in my early 20's and that happened to me as well it took about 4 days before I had feeling in my tongue so shes fine. tell her to keep eating Popsicles and shell be good.
