What else can I help you with?
What atom tends to gain one electron when it combines with another atom?
All elements in the 7th family/group (2nd from the right) on the Periodic Table.
Why atom gain electron?
Yea.
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
Does high value of electron affinity for an atom means that it will gain electron easily?
Yes, that is part of the definition of electron affinity.
Why does a chlorine atom gain an electron when it forms an ion?
Atoms that gain extra electrons become negatively charged. A neutral chlorine atom.
What atom tends to gain one electron when it combines with another atom?
All elements in the 7th family/group (2nd from the right) on the Periodic Table.
Why atom gain electron?
Yea.
How Atoms can accept or lose electron's. If an atom loses an electron what will its resulting charge be?
Gain of an electron transform the atom in an anion.Loss of an electron transform the atom in a cation.
What happens when an atom that has lost an electron in contact with an atom that has gain an electron?
They form an ionic compound.
When Group 7A elements in a periodic table form ions they lose or gain protons?
When Group 7A elements form ions, they gain an electron to achieve a stable electron configuration. This causes the atom to have a net negative charge since it now has one more electron than protons present in its nucleus.
How atoms gain electron?
when an any atoms want to achieved a state of nearest an inert atom, its gain electron
What an atom has to do to become an ion?
Lose or gain an electron
Does a metallic atom and a nonmetallic atom both gain electron?
No. A metallic atom will typically lose electrons.
What is the difference between electron affinity and electron gain enthalpy?
Electron affinity is the energy released when an atom gains an electron to form a negative ion, while electron gain enthalpy is the enthalpy change accompanying the addition of an electron to a gaseous atom. Electron affinity is a specific term used in the context of forming an ion, while electron gain enthalpy is a general term for the enthalpy change associated with gaining an electron.
An atom of chlorine and an atom of bromine have the same?
An atom of chlorine and an atom of bromine both have the same number of valence electrons in their outermost shell, which is 7 electrons. This makes them both part of Group 17 of the periodic table, known as the halogens. Each atom will typically gain one electron to achieve a stable electron configuration.
Why does an atom have charge?
The atom may gain or lose an electron either making it positive or negative.
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
