What else can I help you with?
How many electrons must be gained or lost for each of the following to achieve a noble gas electron configuration Lithium atom Bromine atom Barium ion Helium atom?
sodium must lose 1 electron, helium is a noble gas it is in group 8 check your periodic table, sufide ion must gain 2 electrons
If the element sulfur S was to lose two electrons per atom what would the net ionic charge be?
The charge will be +2.
What of atom tends to lose one electron?
An atom that tends to lose one electron typically has fewer electrons than protons in its nucleus. These atoms are usually found in Group 1 or Group 2 of the periodic table, such as elements like sodium or magnesium. When they lose one electron, they form positively charged ions called cations.
What must have happened to a calcium atom for it to achieve a noble gas structure?
A calcium atom must lose 2 electrons to achieve a noble gas structure, as it will then have the same electron configuration as argon, a noble gas. This loss of electrons allows the calcium atom to have a full outermost electron shell, giving it greater stability.
What would make an atom of 12 protons and electrons a positive two cation?
A cation is a positive ion. To get 2 positive charges the atom would need to lose 2 electrons. As its configuration is 2,8,2, this is what it is likely to do when it reacts as the resulting ion has an inert gas structure.
An atom releses an bata particle. what two things does an atom lose. the element becomes?
It loses 2 proton and 2 nutron
How many electrons does a magnesium atom need to lose to become stable?
2
How many electrons must be gained or lost for each of the following to achieve a noble gas electron configuration Lithium atom Bromine atom Barium ion Helium atom?
sodium must lose 1 electron, helium is a noble gas it is in group 8 check your periodic table, sufide ion must gain 2 electrons
How does an ion with a charge of 2 form?
For a neutral atom to become an ion with a 2 plus charge it must LOSE TWO ELECTRONS.
What is the smallest possible piece of water?
the smallest possible piece of water would be one water molecule. (one molecule of H2O), consisting of 2 Hydrogen atoms and 1 oxygen atom. Anything smaller, and it would lose the characteristics of water.
Does beryllium's gains or losses ion?
You question is a bit incorrect. Beryllium is a metallic element in Group (II) of the Periodic Table. Being in Group (II) it will have a strong tendency to loose electrons(ionisation). In its neutral state beryllium has the electron structure of 1s2, 2s2, This means that its inner most electron shell (1s) contains two electrons. Its outer most electron shell (2s) also contains two electrons. When beryllium ionises two electrons , they are 'lost' from the outer most (2s) electron shell. They are further from the nucleus of the atom and are not so strongly held.!!!!! When these two electrons have 'gone' , the Beryllium atom is now the Beryllium ION. (It is no longer an atom). Formulaically it is written as Be(g) = Be^(2+) + 2 e^(-) So for beryllium atom to become a Beryllium ION it LOSES TWO electrons.
How do human beings lose water?
1) In the breath (you can see it in the cold). 2) By sweating 3) Urinating. 4) In the stool (if you loose a lot this way it is diarrhea).
In order to become a chemically stable ion a neutral atom of calcium will?
It would have to lose two electrons.
How can you lose 2 stone or more in 1 week?
It is not possible to lose 2 stone or more in 1 week by any natural means.
What is the atomic number of an atom or electron?
Sodium (Na) lose 1 Beryllium (Be) lose 2 Boron (B) lose 3 Nitrogen (N) gain 3 Sulfur (S) gain 2 Fluorine (F) gain 1
How many electrons would an atom of magnesium have to lose to have a stable octe?
It'll have to lose two to have a stable octet.
When a reaction occurs between atoms with the electron configuration 2-8-1 and 2-7 what is the predominant type of bonds formed?
The reaction would likely form an ionic bond where the atom with 2-8-1 would lose its outer electron to the atom with 2-7 configuration, resulting in the formation of ions with opposite charges that are attracted to each other.
