【 】An atom that has lost an electron is called ||What is it called when an atom loses an electron?

An atom that has lost an electron is called ●Choose one. A)Anion B)Cation C)Neutral D)Nothing Answer: An atom that has lost an electron is called  cation.Every cation must have positive charge.For example: If  a neutral hydrogen atom  lose one electron,we get hyrodrogen ion which is a cation.The charge of cation is positive (1+). H(1)=Neutral Hydrogen atom H + =This is a cation of hydrogen. Continue

【】When an atom loses two electrons it becomes a cation What is the charge?||What is the charge of an atom that loses 2 electrons?

When an atom loses two electrons it becomes a cation What is the charge? ◆Choose the answer. A) two negative charges B) two positive charges C) Neutral D)Nothing Answer: When an atom loses two electrons it becomes a cation and the charge of this cation will be +2. Explanation: When an atom loses an electron,it becomes positive ion which is called cation. You know that the charge of proton is positive (+1) and the charge of electron is negative (+1). Besides,we know that an atom is neutral because the number of proton and electron is in same number. Now if one electron goes from the neutral atom,one proton of that atom will not be satisfied.Thus the neutral atom become positively charged. H(1)=one proton and one electron=Neutral atom H+(1)=one proton and zero electron=Positively charged hydrogen atom=Cation He(2)=two protons+two electrons=Neutral atom He2+=two protons+Zero electron=Cation Continue

when an atom loses an electron it becomes quizlet ◆Choose the answer. A) Negative ion B) Positive ion C) Neutral D)Nothing Answer: When an atom loses an electron,it becomes positive ion which is called cation. You know that the charge of proton  is positive (+1) and the charge of electron is negative (+1). Besides,we know that an atom is neutral because the number of proton and electron is in same number. Now if one electron goes from the neutral atom,one proton of that atom will not be satisfied.Thus the neutral atom become positively charged. H(1)=one proton and one electron=Neutral atom H+(1)=one proton and zero electron=Positively charged hydrogen atom=Cation So the charge of atom will be positive (+1) if it loses an electron and this positively charged ion is called cation.
