What is the correct representationfor an atom x with 28 electrons and 30 neutrons.?
To represent an atom, we typically use a symbol notation called the atomic symbol. The atomic symbol consists of the element's abbreviation or symbol, usually derived from its English or Latin name. Additionally, we include the atomic number and the atomic mass.
Given that the atom X has 28 electrons and 30 neutrons, we need to identify the element first. The number of electrons determines an element's characteristics and position in the periodic table. For atoms with 28 electrons, we can determine that the element is nickel (Ni) since nickel has an atomic number of 28.
To determine the atomic symbol, we use the atomic number and the atomic mass. The atomic mass represents the total number of protons and neutrons in an atom. For nickel, the atomic mass is approximately 58.6934.
Therefore, the correct representation for an atom X with 28 electrons and 30 neutrons is:
Nickel-58.6934
