What is the atomic mass of ammonia?Atomic MassFor each element, atomic mass is given on the period table of elements. Atomic mass, represented by a number at the bottom of the symbol for the element that the symbol represents, indicates the number of neutrons and protons combined in said ...
What is the percent composition of (NH_4)_2S? How many elements and stable isotopes are there in nature? What is mass percent composition? How many different elements are in our bodies? How many elements have an atomic number of 42?

The chemical name is composed of the name of the metal,which is written first,foll...
Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chloramine Maintains better residual disinfectant qualities in extensive ...
through the intentional synthesis in nuclear reactors or particle accelerators are calledRadio Active Elements. All elements can have radioactive isotopes. If enough neutrons are added to an atom, it becomes unstable and decays. The increasing atomic number does not necessarily make an atom more ...
In general, an atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it. ...
In this paper we revisit an open problem posed by Aldous on the max-entropy win-probability martingale: given two players of equal strength, such that the win-probability is a martingale diffusion, which of these processes has maximum entropy and hence gives the most excitement for the spectator...
Each element has a uniqueatomic number, which is the number of protons it has. This is how we identify one element from another. Theperiodic table of the elementslists all of the discovered elements and their atomic numbers. Examples of elements include oxygen (O), carbon (C), and gold ...
What is the electron configuration of \left[N(CH2CH3)4\right]2CoCl4? and \left[Co(NH3)6\right]Cl3? An atomic cation with a charge of +1 has the following electron configuration: (Ar) 4s^2 3d^{10} 4p^1. What is the chemical symbol for the ion?
