In the case of atoms, it has protons, neutrons, and electrons in it, and each of these sub-atomic particles carries a definite mass, although a neutron is chargeless it has a mass. Answer and Explanation: Atomic mass Th...
A certain element has its outermost electron in a 3p subshell. It has valence +3 because it has three more electrons than a certain noble gas. Identify the number of electrons in the ground-state outer shell of atomic phosphorous. What is the order of the number of free electron...
We know, that number of atoms of an element =number of molesxxN(A)xxatomicity =("mass of the element (g)")/("gram-atomic mass of element")=xxN(A)xxatomicity (becauseGram-atomic mass of Au=197) (2) No. of atoms present in 1 g of Na=(1)/(23)xx6.022
Has a mass about the same as that of a proton 4. Is att The nucleus of an atom consists of which particles? Name three subatomic particles found in the atom of an element. If an atom has 17 electrons, 20 neutrons, and 19 protons, what is its approximate ...
Bismuth is the most naturally diamagnetic element and has one of the lowest values of thermal conductivity among metals. Bismuth was long considered the element with the highest atomic mass that is stable, but in 2003 it was discovered to be extremely weakly radioactive: its only primordial ...
The period of an element with electron configuration 1s2 2s2 2p6 3s2: a. 3. b. 1.How many electrons can be in the n=6 l=2 subshell?A neutral atom of an element has 2K, 8L, 9M, and 2N electrons. Find out the following: (a) Atomic number (b...
lastly, Neueroeffnungen sneakily forms a ue element neither constituent word (neu, Eröffnungen) possesses, but is still processed correctly (despite the mismatched casings as well) On request, replacements may be forced, as is potentially useful for names: $ echo 'Frau Loetter steht ueber der...
- Hint: We have to calculate the number of moles of every element in the given options and the element which has the maximum number of moles will have the largest number of atoms. The number of atoms in 1 mole of an element is determined by Avogadro's number.How...
A perfect cube of aluminum metal was found to have a mass of 20.00 g. The density of the aluminum is 2.70 g/ mL. What are the dimensions of the cube? What determines which type of radioactive decay occurs on a specific element (e.g....
which results in alignment of the IC die to both the bridge device and the package substrate. With this process, the element is incorporated into the melt by, e.g., using a small mass of low melt solder on one side and large amount on the other side, or by using a metallurgy (such...
