6.1 Ions: Transfer of Electrons
The elements are found in nature combined as compounds.
There is an explanation for the stability of noble gases.
Stable electron arrangements can be formed when electrons are shared between atoms.
Some elements have the stability of helium with two electrons.
The atoms of H2O and C3H8 share electrons.
The metal atoms lose their electrons easily.
They form ion with positive charges.
A metal atom has the same arrangement of electrons as its nearest noble gas.
The covalent bond atom has a stable arrangement of electrons.
sodium has 10 negatively charged electrons instead of 11.
The atom is no longer neutral because of the 11 positively charged protons in its nucleus.
The ionic charge of 1+ is written in the upper right corner of the Lewis A atom.
The 1 is understood in a cesium ion.
The ion has 55 protons and 54 electrons, which is smaller than the atom.
Magnesium, a metal in Group 2A (2), obtains a stable electron arrangement by losing two electrons to form a magnesium ion.
The magnesium atom is larger than the magne sium ion because the electrons in the third energy level were removed.
The magnesium ion has octets of electrons that fill its second energy level.
The energy of a nonmetal atom is high.
A stable electron arrangement is obtained when a nonmetal atom gains one or more electrons.
A negatively charged ion is formed by gaining electrons.
An atom of chlorine with seven electrons gains one electron to form an octet.
The chlorine atom is no longer Writing Positive and Negative Ions neutral because it now has 18 electrons and 17 protons in its nucleus.
The ion has 7 protons and 10 electrons.
The ion has 20 protons and 18 electrons.
Nitrogen has 7 protons.
In an ion of nitrogen with 10 electrons, the ionic charge would be 3-.
The element has 20 protons.
In an ion of calcium with 18 electrons, the ionic charge would be 2+.
In ionic compounds, representative elements usually lose or gain electrons to give eight valence electrons like their nearest noble gas.
The group numbers in the periodic table can be used to determine the charges for the representative elements.
The elements lose two electrons to form an ion.
The elements in Group 3A lose three electrons to form an ion.
The elements in Group 7A gain one electron to form an ion.
The elements in Group 6A gain two electrons to form an ion.
The elements in Group 5A gain three electrons to form an ion.
Nonmetals of Group 4A do not form ion.
Group 4A (14) has metals that lose electrons to form positive ions.
The ionic charges for some elements are listed.
Consider the elements oxygen and aluminum.
The number of valence electrons is stated.
The number of electrons that must be lost or gained is stated.
Write the symbol and name for each ion.
The symbols for the ion are written.
The body fluids have important functions.
Foods such as bananas, milk, cheese, and potatoes help regulate body functions.
Milk, cheese, bananas, cereals, and potatoes are important for the body.
