When tomatoes were planted in steamed soil inoculated with spores of Didymellalycopersici Kleb., a large proportion became infected but very few became infectedin unsteamed soil similarly inoculated. In soil tr
In physics, the term electron can be defined as the type of basic unit that forms an atom. It is the primary source for the flow of electricity within solid materials. The electrons are said to have a negative charge. Answer and Explanation:1 ...
The number of electrons in 3d shell foe element with atomic number 26 is A4 B6 C8 D10Submit The element with an atomic number 26 is AA non-metal BKrypton CIron DManganeseSubmit The number of electrons in the M shell of the element with atomic number 24 is A24 B12 C13 D8Submit ...
An atom is composed of three particles -- protons, neutrons and electrons. The number of protons is the defining characteristic of an element, and this number also tells you how many electrons are present in a neutral atom. Therefore, iron -- with an atomic number of 26 -- has 26 proton...
An element that has the electron configuration (Ne)3s2 is in the group: a. 2. b. 5. Determine the number of (a) electrons, (b) protons, and (c) neutrons in iron (2656 Fe). What is the ratio of the number of electrons for each atom of lead over one atom of aluminum?
