Learn about the alkali metals group and explore the group 1A elements. Understand their charge, valence electrons, ions, and find out whether they are soft or hard. Related to this Question How many protons does cesium have? What is the atomic number of rubidium?
In a neutral atom, the number of electrons is equal to the number of protons in the nucleus. This number is also known as the atomic number. Electrons inside the atoms revolved around it in orbits of various radii. The position of an electron can be determined from its electronic ...
Valence electrons a) occupy the inner, or least, energy level of electron orbits around the nucleus b) determine the chemical reactivity of an element c) are always the same number as the number of protons plus neutrons in the nucleus d) are those elect ...
The atomic number uniquely defines an element. Each element has its atomic number. The atomic number is also equivalent to the number of protons present in the nucleus of the atom. For neutral atoms, the number of protons and the number of electrons a...
Fluorine has a total of 9 electrons. a. Write out the electronic configuration and filling order for the 9 electrons. b. Write a set of quantum numbers for the third and the eighth electrons of the F atom. Determine the total...
No matter how many neutrons or electrons it has, an atom with one proton is alwaysatomic number 1and always hydrogen. An atom the contains 6 protons is by definition an atom of carbon. An atom with 55 protons is always cesium. How to Find the Atomic Number How you find the atomic numb...
