How many electrons would hydrogen need to have a full outer she?
Hydrogen has one electron in its outer shell and typically needs one more electron to achieve a full outer shell, which would complete its valence shell with two electrons (like helium). Therefore, hydrogen would need one additional electron to have a full outer shell.
How many electrons fill the outer shell in hydrogen?
An energy level is the fixed amount of energy that a system described by quantum mechanics, such as a molecule, atom, electron, or nucleus, can have. There are no full energy levels in an atom of hydrogen. The first energy level of any atom can hold 2 electrons. Hydrogen only has one electron and it is in the first energy level.
What element that has 1 electron?
Hydrogen has 1 electron in its outer shell. other elemnts also have just one electron in their outer shell, the alkali metals, group1; lithium, sodium potassium, rubidium, caesium, frankium the coinage metals, group 11; copper, silver, gold
What element has only one electron in the outer energy level?
All atoms in the first group (column) of the periodic table have only one electron in the outer shell. Those heavier than hydrogen (H) are called the alkali metals. The alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). All have an outer s electron shell. The question asks for a single element in an "outer energy level" and all seven of these atoms fit the question. There are other atoms which may be characterized as having a single outer electron, but the chemistry and physics of those atoms make things a bit more complicated and a longer discussion would be necessary instead of a simple answer to a simple question.
Would hydrogen and fluorine form an ionic bond?
Hydrogen and fluorine would not form an ionic bond. Instead, they would form a covalent bond due to their similar electronegativities. In a covalent bond, they share electrons to achieve a full outer electron shell.
How many atoms does hydrogen need for its energy level to be full?
One atom is needed to full the outer shell of a hydrogen atom, this is bacuse in GCSE terms electrom structure goes 2,8,8,2 and hydrogen only has one shell, so it would need 2 to complete this shell. This is the same for A-level however we refer to electron structure in spd, the electron structure of hydrogen then would be 1s1.
Which element has 1 valence electron and is in period 1.?
The element with 1 electron in period 1 would be hydrogen.
Why only 12 elements form ions easier than the rest of the elements in periodic table?
I would imagine that these elements are hydrogen, the alkali metals and the halogens. Hydrogen and the alkali metals only have one outer electron, which is easier to displace than the two outer electrons of the alkaline earth metals, for example. In contrast, the halogens only need one more electron to have a complete outer shell; it is easier to accept one electron than the two electrons needed by the chalcogens - oxygen, sulphur, selenium etc.
Chlorine will tend to lose all of its seven outer electron or gain one electron?
Chlorine will tend to gain one electron to achieve a stable electron configuration with a full outer shell. This results in the formation of the chloride ion, which has a full outer shell of electrons.
Is it true that all noble gases have at least three shielding layers?
No. Not sure what you mean by a shielding layer- I would take this as the filled electron shells below the "outer", highest energy layer-- He has none, Neon has one , Argon has two.
Is hydrogen positive or negative?
A hydrogen atom is neutral as it has the same number of protons and electrons. But as an ion, it can be either positive or negative.We usually talk about it in the positive sense; eg. It would donate it's outer electron and gain a positive charge; H+. However, in some compounds it can have a negative charge, H-.In a standard question though, always assume that it loses it's outer electron and is positively charged unless told otherwise in the question.
What color would be given off by an electron shifting from level 6 to level 2 in hydrogen?
Hydrogen has only one electron on one shell.
