In addition to hydrogen, all elements in Group I of the periodic table have one valence electron. They are lithium, sodium, potassium, rubidium, cesium, and francium.
The farther you move right on the Periodic Table the more valence electrons. For example, elements in Group VII have 8 valence electrons except helium.
What else can I help you with?
What is the number of valence electrons for the elements in group 1?
Elements in group 1 (alkali metals) have 1 valence electron. This single electron is in the outermost energy level of the atom, making these elements very reactive and likely to lose this electron to achieve a stable electron configuration.
How many valence electrons are in the sodium family?
Elements in the sodium family (Group 1A or Group 1) have 1 valence electron. This is because they have one electron in their outermost energy level.
Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
The most reactive elements have how many valence electrons?
The most reactive elements require to lose or gain the least number electron(s) to attain a noble gas structure. These are elements in group one as they need to lose one electron, and elements in group seven as they need to gain one electron.
Which element had only one valence electron?
The elements with only one valence electron are a part of the Alkali Metals: * Lithium * Sodium * Potassium * Rubidium * Cesium * Francium Hydrogen also only has one valence electron, but it is not considered part of the Alkali Metals family, nor any other family.
What is the number of valence electrons for the elements in group 1?
Elements in group 1 (alkali metals) have 1 valence electron. This single electron is in the outermost energy level of the atom, making these elements very reactive and likely to lose this electron to achieve a stable electron configuration.
The elements in group 7A have one valence electron true or false?
A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.
Are all elements with one valence electron highly combustible?
Not all elements with one valence electron are highly combustible, but some are. Elements like lithium (Li) and potassium (K) with one valence electron can be highly reactive and flammable. However, elements like helium (He) and neon (Ne) with one valence electron are inert and not combustible.
What has one valence electron and reacts with other elements?
Any element in column 1 of a wide form periodic table has exactly one valence electron and reacts with other elements.
What is the number of valence electron for all the elements in periodic table group 1A 1?
Group 1A (1) elements in the periodic table all have 1 valence electron. This includes elements like hydrogen, lithium, sodium, and potassium.
How many valence electrons are in the sodium family?
Elements in the sodium family (Group 1A or Group 1) have 1 valence electron. This is because they have one electron in their outermost energy level.
What is the number of valence electrons in group one?
Valence electrons are the electrons in the furthest electron shell from the nucleus.For the first three rows, essentially, the number of valence electrons is the number of squares the element is away from the beginning of the row at the left.For example. Sodium is the first (group 1) it has 1 valence electron. Magnesium is the second, it has 2 valence electrons.
Group 1a elements have how many electrons in their valence shells?
All these have one electron in their valence shell.
Are all elements with one valence electron conductive?
No. For example, Hydrogen is an element with one valence electron, but it is a non-conductive gas under standard conditions.
Why does a d-block elements a variable valency?
because they have one valence electron
The most reactive elements have how many valence electrons?
The most reactive elements require to lose or gain the least number electron(s) to attain a noble gas structure. These are elements in group one as they need to lose one electron, and elements in group seven as they need to gain one electron.
Elements that have one valence electron?
Elements in Group 1. (eg. Hydrogen, Lithium, Sodium etc.)
