Magnesium is in Group 2. It has two electrons in its outer shell. When these electrons are lost, a magnesium ion, Mg 2 + , is formed. A magnesium ion has the same electronic structure as a neon atom (Ne).
What is true about a neutral magnesium atom?
For a neutral atom, they contain the same number of protons and electrons . Therefore, a Mg atom would contain 12 protons since it has an atomic number of 12, and since it is electrically neutral it has the same amount of electrons as well.
Why are atoms of magnesium neutral?
Explanation: ....and they gots 12 negative charges, owing to the 12 electrons that are conceived to orbit the nuclear core. Because there are EQUAL positive and negative electronic charges , the overall charge on the atom is NEUTRAL. Magnesium tends to lose 2 electrons to form a Mg2+ cation.
Is the magnesium atom electrically neutral?
Similarly, we can observe magnesium. When it is an atom, it has 12 protons and 12 electrons. Thus, it is a neutral atom .
Why does an atom have a neutral charge?
Electrons have electric charge of -1 and the number of electrons in an atom is equal to the number of protons . ... Heavier atoms tend to have more neutrons than protons, but the number of electrons in an atom is always equal to the number of protons. So an atom as a whole is electrically neutral.
What element is a neutral atom of magnesium?
Protons are positively charged particles that carry a +1 charge, while electrons are negatively charged particles that carry a -1 charge. So, for instance, you have a neutral magnesium atom ( Mg ).
What is the mass number for neutral magnesium atom?
| Name Magnesium | Atomic Number 12 | Atomic Mass 24.305 atomic mass units | Number of Protons 12 | Number of Neutrons 12 |

Why do ions in magnesium oxide stay together?
Mg loses two electrons to have an octet. Oxygen gains two electrons to have an octet. The ionic bond between ions results from the electrostatic attraction of opposite charges . The final formula of magnesium oxide is MgO.
What happens if an atom is not neutral?
If an atom is not neutral, then it will form an ion . In this case, the number of protons and electrons are not equal. If the atom loses one or more electrons, it will have more protons than electrons, and will form a positively charged ion (cation).
Why does magnesium have no overall charge?
(b) Explain why a magnesium atom has no overall charge. Magnesium has an atomic number of 12 which means it has 12 protons (in its nucleus). ... As an atom it has 12 electrons; electrons have a – charge. With 12 protons (12+) and 12 electrons (-) it has a net charge of zero; the atom has no overall charge.
Which atom is not neutral?
Atoms that are not electrically neutral are called ions and examples of atoms frequently found in their ionic for include sodium, chlorine and magnesium.
Are all atoms in periodic table neutral?
All the atoms presented on the Periodic Table are electrostatically neutral ....
Which two atoms have the same number of neutrons?
Two atoms with the same atomic number, but different mass numbers (same number of protons, different number of neutrons), are called isotopes , or isotopic nuclides. Having different numbers of neutrons changes the mass of these atoms, so isotopes have slight variations in their physical and chemical behavior.
Is electrically neutral?
Why is an atom electrically neutral?. An atom is electrically neutral because the overall charge of an atom is zero . The atoms are made of three subatomic particles called protons, electrons and neutrons. Protons are positively charged particles, electrons are negatively charged and neutrons are neutral.
