Looking at the Periodic Table we see that magnesium has an atomic number of 12, thus has 12 protons. To keep it neutral, it must also have 2 electrons. Filling in the first 12 electron orbitals gives us an electron configuration of 1s2 2s2 2p6 3s2. Thus, magnesium also has 2 valence electrons and so is your answer.
What else can I help you with?
What is the charge on a magnesium ion that has 10 electrons?
Magnesium has 12 protons, so if there are only 10 electrons, then it will have a +2 charge.
What is the symbol for sodium with 11 protons and 10 electrons?
The symbol for sodium with 11 protons and 10 electrons is Na+. The plus sign indicates that the sodium atom has lost one electron, resulting in a positive charge.
A sodium ion has 11 protons and 10 electrons what is its charge?
A sodium ion with 11 protons and 10 electrons has a net charge of +1 because the number of protons (positive charge) is greater than the number of electrons (negative charge) by 1.
If a calcium atom has 20 protons and 20 neutrons and 18 electrons what is the magnitude of it's charge in coloumbs?
The charge of a calcium atom with 18 electrons will be +2 elementary charges since it has 20 protons and 18 electrons, resulting in a net positive charge. Each elementary charge is approximately 1.602 x 10^-19 Coulombs, so the total charge of the calcium atom would be 2 * 1.602 x 10^-19 Coulombs.
A neutral atom contains 5 neutrons and 4 protons how many electrins does it contain?
Protons: 5 Neutrons: 7 Electrons: 5
What would the charge be with 13 protons 14 neutrons 10 electrons?
The charge of an atom is determined by the difference between its protons and electrons. In this case, the atom would have a +3 charge since it has 13 protons and 10 electrons, leading to an excess of positive charge.
If an atom has 9 protons and 10 neutrons in it's neucleus and has 10 electrons what is the overall charge?
The overall charge of the atom would be positive one, since it has 9 protons (positive charge) and 10 electrons (negative charge), resulting in a net charge of +1.
What is the charge of the three parts of an atom of neon?
An atom of neon consists of protons, neutrons, and electrons. Neon has 10 protons, 10 neutrons, and 10 electrons. Protons are positively charged, electrons are negatively charged, and neutrons have no charge.
Why the electrical charge in an atom is zero or neutral?
There is a neutral charge on an atom when the number of protons is equal to the number of electrons. This is most common in the Noble gases, such as Neon (atomic number 10, the second Noble Gas), where there are 10 protons and 10 electrons, with the negative charge on the electrons balancing out the positive charge of the protons exactly.
How does the balance of protons and electrons determone whether an atom is electrically charged?
If the number of protons is the same as the number of electrons, the atom is Neutral (the +'s and the -'s cancel out, leaving no net charge). If there are more electrons than protons, then the atom is negatively charged. If there are more protons than electrons, then the atom is positively charged. A Helium atom has 2 protons and 2 electrons: ++ --: No net charge: Neutral. A Chloride ion has 17 protons and 18 electrons: 17+ 18 -: Net charge -1: Negative (anion). A Sodium ion has 11 protons and 10 elections: 11+ 10-: Net charge +1: Positive (cation.
What would the charge of an atom be if it has six protons ans six electrons?
An atom has no net charge, and is therefore neutral, as long as the number of protons is the same as the number of electrons. There would be no charge. If there is the same number of protons to electrons, there would be no extra attraction to create a charge.
What if their are 8 protons in an atom how many electrons are their?
If it is neutral, there would be equal protons and electrons. However, if it is a charged ion, then there could be more or less electrons than protons. For example, 8 protons and 7 electrons would give +1 charge. 8 protons and 10 electrons would give -2 charge. Each proton has a +1 charge. Each electron has -1 charge.
When an atom has more protons than electrons what is its electrical charge?
No. An 'atom' can not have more electrons than protons because, by definition, an 'atom' is electrically neutral. If an 'atom' loses or gains an electron, it becomes an 'ion' and is electrically charged. An 'ion' with more electrons than protons will be NEGATIVELY charged because electrons carry negative charge.
What is the difference between an electrically charged atom or a electrically balanced atom?
Most atoms are electrically balanced because they have the same number of protons, which have a charge of +1, and electrons, which have a charge of -1. However electrons can be lost or gained. When they are, the atom has a different number of protons to electrons so it becomes charged. Example. An uncharged atom of oxygen has 8 protons and 8 electrons. Sometimes it gains two electrons. This means that it has 8 protons but 10 electrons. +8 -10 = -2. therefore the charged atom of oxygen has a charge of -2.
What is the electrical charge of a fluorine atom?
A fluorine atom has a negative electrical charge of -1 due to its 9 protons and 10 electrons.
Why does an atom that has lost an electron have a positive charge?
Every atom has a positively charged nucleus containing protons, each with a 1+ charge. Electrons, each with a -1 charge surround the nucleus. In a neutral atom the number of electrons is equal to the number of protons, so there is no net charge. If an atom loses electrons it will have more protons than electrons resulting in an overall positive charge. For example, a neutral magnesium atom has 12 protons and 12 electrons, resulting in an ion with 12 protons and 10 electrons. Since there are two more protons than electrons in this ion, the overall charge is 2+
What kind of charge will an atom have if it gains or loses one or more electrons?
If an atom loses an electron, it will be positively charged. An example may make this clearer. A neutral carbon atom has 6 protons and 6 electrons. If you take away an electron, you will have 6 protons and 5 electrons, for a total charge of +6 -5 = +1.
