How many electrons will group 13 lose or gain?
Al, Ga, and In each lose 3 electrons. Its easy to remember, because there are three of them and they each lose three electrons. The other elements in group 13 vary
Why the oxidation states vary in a periodic but remains almost constant in a group?
Because within a group, the elements all have the same number of valence electrons, so their "combining power" (oxidation number) is relatively the same. In a period, the number of valence electrons increases going left to right, so the "combining power" changes.
Why the oxidation state vary in periods but remains constant in a group?
The oxidation state varies in periods because elements in the same period have different numbers of electron shells, which affects their ability to gain or lose electrons. In a group, elements have the same number of valence electrons, leading to similar chemical properties and consistent oxidation states.
How many electrons are required in the outer energy level for most elements to be stable?
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
How does the periodic table indicate the numbers of valence electrons an element has?
The group number of an element on the periodic table corresponds to the number of valence electrons it has. For main group elements (groups 1, 2, 13-18), the ones digit of the group number gives the number of valence electrons. For transition metals and inner transition metals, the number of valence electrons can vary.
How many electrons will group 13 lose or gain?
Al, Ga, and In each lose 3 electrons. Its easy to remember, because there are three of them and they each lose three electrons. The other elements in group 13 vary
Which elements can lose electrons from the two outermost shells?
Elements in Groups 1 and 2 (alkali metals and alkaline earth metals) can easily lose electrons from their outermost shells. Group 13 elements like Boron, as well as Group 17 elements like Halogens, can also lose or gain electrons from their two outermost shells, though the valency may vary.
Why the oxidation states vary in a periodic but remains almost constant in a group?
Because within a group, the elements all have the same number of valence electrons, so their "combining power" (oxidation number) is relatively the same. In a period, the number of valence electrons increases going left to right, so the "combining power" changes.
Based upon the location of group IV on the periodic table the ionic charge of the elements in it should be?
Group IV elements, which include carbon, silicon, germanium, tin, and lead, typically have four valence electrons. While they can form ions, they are more commonly found in covalent bonding due to their tendency to share electrons. When they do form ions, they can exhibit a +4 charge by losing all four valence electrons or a -4 charge by gaining four electrons, although the latter is less common. Overall, their ionic charge can vary, but +4 is the most representative for this group.
Why the oxidation state vary in periods but remains constant in a group?
The oxidation state varies in periods because elements in the same period have different numbers of electron shells, which affects their ability to gain or lose electrons. In a group, elements have the same number of valence electrons, leading to similar chemical properties and consistent oxidation states.
How do you determine the number of valence electrons if you know the group no of elements?
valence electrons are electrons at the outermost shell as we all know, group in PE can be determined by looking at the valence electron thus if it is in group 1..then the valence electron is 1
How many electrons are required in the outer energy level for most elements to be stable?

For transition metals and inner transition metals, the number of valence electrons can vary.
The number of electrons in its bonding shell?
number of electrons in the bonding shell vary according to the element. for example group 1 in the periodic table contains elements with ony one electron in their bonding shell, similarly group 2 has elements with two electrons in its bonding shell and so on. the group number in the periodic table denotes the number of electrons in the bonding shell of each element present in that particular group
How many electrons are in the highest occupied energy level of oxygen?
Oxygen atoms have 6 electrons in the highest occupied energy level. They are two 2s electrons and four 2p electrons. All elements in Group 16 have 6 valence electrons. For Groups 13-18, subtract 10 from the group number and that gives you the number of valence electrons (the electrons in the highest energy s and p orbitals). The Group 1 elements have one valence electron and the Group 2 elements have two valence electrons. The transition metals can vary in the number of valence electrons. You can't necessarily go by group number for them.
How does the ionization energy vary with atomic number within the group?
Ionization energy generally decreases as you move down a group in the periodic table. This is because as you move down a group, the outermost electrons are farther from the nucleus, resulting in weaker attraction and easier removal of electrons.
When moving down a group ( family) in the periodic table the number of valence electrons?
When moving down a group, the number of valence electrons do not change. This similarity yields the elements in the same groups to have same chemical properties. For example, elements in group 17 obtain one electron to stabilize as -1 ion.In a group, all the elements have a same number of valence electrons. So their chemical properties are equal. But the physical properties vary.Valence electrons are the electrons in outermost shell.The valence electrons remain same in a group. For example-Group-1 elements have 1 valence electron.
