If an atom contains one electron and one proton what charge will it carry

Term Meaning Elementary charge ( e e e e ) Smallest possible unit of charge. Equal to the charge on one proton or the magnitude of charge on one electron, which is 1.6 × 1 0 − 19 C 1.6 \times 10^\,\text C 1 . 6 × 1 0 − 1 9 C 1, point, 6, times, 10, start superscript, minus, 19, end superscript, start text, C, end text . Also called electron charge. Sometimes uses symbol q e q_e q e ​ q, start subscript, e, end subscript . Net charge Sum of the charges on an object. Coulomb (C) SI unit for electric charge. The amount of charge transferred in 1 s 1\,\text s 1 s 1, start text, s, end text by a current of 1 A 1\,\text A 1 A 1, start text, A, end text . When charge is transferred between objects, it’s only the electrons that move. An electron can’t be broken into smaller pieces, so charge always changes in multiples of the elementary charge. This property of electrons means that charge is quantized and the charge on any object must be an integer multiple of the elementary charge. An object’s charge can be 0 e , 1 e , − 1 e , 2 e 0\,e, 1\, e, -1\, e, 2\, e 0 e , 1 e , − 1 e , 2 e 0, e, comma, 1, e, comma, minus, 1, e, comma, 2, e , etc., but not 1 4 e , 1 2 e \dfrac\, e 4 1 ​ e , 2 1 ​ e start fraction, 1, divided by, 4, end fraction, e, comma, start fraction, 1, divided by, 2, end fraction, e , etc. Nope, your question isn't dumb at all! I believe you would call it "charge of negative two" for the first one and "charge of two". You can omit the "protons" portion as one unit of ...

In ordinary chemical reactions, the nucleus of each atom remains unchanged. Electrons, however, can be added to atoms by transfer form other atoms, lost by transfer to other atoms, or shared with other atoms. The transfer and sharing of electrons among atoms govern the chemistry of the elements. During the formation of some compounds, atoms gain or lose electrons, and form electrically charged particles called ions(Figure \(\PageIndex\): Some elements exhibit a regular pattern of ionic charge when they form ions. Example \(\PageIndex\): Composition of Ions An ion found in some compounds used as antiperspirants contains 13 protons and 10 electrons. What is its symbol? Solution Because the number of protons remains unchanged when an atom forms an ion, the atomic number of the element must be 13. Knowing this lets us use the periodic table to identify the element as Al (aluminum). The Al atom has lost three electrons and thus has three more positive charges (13) than it has electrons (10). This is the aluminum cation, Al 3+. Example \(\PageIndex\): Formation of Ions Magnesium and nitrogen react to form an ionic compound. Predict which forms an anion, which forms a cation, and the charges of each ion. Write the symbol for each ion and name them. Solution Magnesium’s position in the periodic table ( 2+, and it is called a magnesium ion. Nitrogen’s position in the periodic table ( 3−, and it is called a nitride ion. Exercise \(\PageIndex\) Aluminum and carbon react to form an io...
