What element has 12 electrons 12 protons and 14 neutrons?
This would be magnesium, based on the number of protons. Since the protons is equal to the number of electrons it is a neutral atom. Given the number of protons in the atom, the isotope would be magnesium-26.
How many protons neutrons and electrons are in Bi?
Five proton and electrons, 6 neutrons. This because this is the atomic number of boron, which states how many protons and electron in the element. For neutrons you must subtract the atomic number (5 in this case) from the rounded. average atomic mass.
How many electrons does Magnesium need to complete the last shell?
A magnesium atom would need 6 electrons to complete its highest occupied electron shell. In practice, a magnesium atom almost never does this, because the energy required would be too great. Instead, the magnesium atom transfers 2 electrons to one or more atom that are more electronegative than magnesium and thereby forms a magnesium ion with an electrical charge of +2. In this ion, the highest occupied shell of a magnesium atom is completely empty of electrons.
How do protons neutrons and electrons determine the properties of an atom?
the number of electron can determin if the element is very reactive or not eg sodium has 11 electrons. sodium is very reactive because of its eletron arangement.
Why is calcium more reactive than magnesium?
Calcium is more reactive than magnesium because it is larger than a magnesium atom because it has one more energy level. Valence electrons are on the outermost occupied energy level in the atom and they cause the atom to react, and thus the further the Valence electrons are from the nucleus, the more reactive they are. Therefore, calcium is more reactive than magnesium because the valence electrons on the calcium atom is farther from the nucleus.
How many electron configurations does magnesium have?
2 Because Magnesium only has 2 electrons in it's outer shell
What is the number of charged protons neutron and electron in magnesium?
Each magnesium atom has 12 electrons and 12 protons (which are always charged), because magnesium has an atomic number of 12. In order to find the number of neutrons, the atomic mass number must be known. The number of neutrons can be determined by subtracting the number of protons from the atomic mass number.
Why is mass number calculated with only the protons and neutrons and not electrons?
Because the mass of electron is negligible when compared to the mass of protons or neutrons.
How many electrons and neutrons does the element of ununoctium have?
Ununoctium has 118 protons, 118 electrons and 176 neutrons.
What element has 12 electrons 12 protons and 14 neutrons?
This would be magnesium, based on the number of protons. Since the protons is equal to the number of electrons it is a neutral atom. Given the number of protons in the atom, the isotope would be magnesium-26.
Why is the ionization energy needed to remove the first two electrons from Magnesium atoms relatively low?
magnesium has a 2 valence electrons. because the third electron is not a valence electron, or in the outer shell, much more energy would be needed to remove it
Why electron is lightest subatomic particle?
Out of electrons, protons, and neutrons, neutrons are the heaviest subatomic particle, with a mass of about 1838 times that of the electron. (If you are asking about electrons, up quarks, and down quarks, then electrons still aren't the heaviest Down quarks are the heaviest, with almost 10 times the mass of an electron.)
What is the smallest of the 3 particles of an atom?
Out of protons, neutrons, and electrons, electrons are the smallest.
How many protons neutrons and electrons are in Bi?
Five proton and electrons, 6 neutrons. This because this is the atomic number of boron, which states how many protons and electron in the element. For neutrons you must subtract the atomic number (5 in this case) from the rounded. average atomic mass.
An atom is neutral and an electron had a charge of -1.6X10 -19 c?
An atom?æconsist of protons,electrons and neutrons. Protons are positively charged, electrons are negatively charged,?æ while neutrons are not charged.?æIts neutral because the number of protons and electrons are equal.
How do protons neutrons and electrons differ in terms of mass electrical charges and locations in the atom?
a neutron's location in an atom is in the core, or nucleus, of that atom, this nucleus is made of both neutrons and protons. the electrons of an atom are located in the electron cloud that surrounds the nucleus. to picture this, imagine a baseball field. the pitchers mat is the nucleus, and all the remaining area of the field, including the bleachers, is the electron cloud. everyone in that field, when spread out evenly among the field, are the electrons.
Why is an atom electron neutral?
Because the Protons (+1) Cancel out the electrons (-1) and leaves the Neutrons which has a neutral charge.
