How many electrons does an atom need to a outer energy level?
There are different numbers of valence electrons in different elements.
How many electrons does aneutral atom with 2 protons and 3 neutrons have?
2: A neutral atoms must have the same numbers of protons and electrons.
How many protons and electrons does an osmium atom have A niobium atom?
An osmium atom has 76 protons and 76 electrons, as the number of protons equals the number of electrons in a neutral atom. A niobium atom has 41 protons and 41 electrons. These numbers correspond to their respective atomic numbers on the periodic table.
Why do the transition metals have multiple oxidation numbers?
Transition metals have multiple oxidation numbers because of their ability to lose different numbers of electrons from their outermost d orbitals. These d orbitals can accommodate varying numbers of electrons, resulting in different oxidation states for transition metals based on how many electrons they gain or lose during chemical reactions.
How many valence electrons in outermost shell?
Different elements have different numbers of valance electrons, which is the main reason why they also have different chemical characteristics.
what elements have equal numbers of electrons and valence electrons?
hydrogen and helium
