How many electrons does S2- have if sulfur has an atomic number of 16?
A sulfide ion, S2-, has 18 electrons. A neutral sulfur atom has 16 electrons, the same as the number of protons, which is the atomic number. Since electrons have a negative charge, a sulfur atom must gain two extra electrons in order to form the sulfide ion with a charge of 2-.
How does an atom of sulfur-36 become a sulfide ion with a -2 charge?
An atom of sulfur-36 can gain two electrons to become a sulfide ion with a -2 charge. When it gains these two electrons, it achieves a stable electron configuration, similar to the noble gas configuration of argon, resulting in a charge of -2.
How many valence electrons are in a sulfur atom and a sulfide ion?
A sulfur atom has 6 valence electrons, while a sulfide ion has 8 valence electrons because it gains two electrons to achieve a stable electron configuration.
How many electrons does n need to gain to becom isoelectronic with a noble gas?
An atom with atomic number n needs to gain enough electrons to have the same number of electrons as the nearest noble gas in the periodic table. This would typically involve gaining 8 electrons to achieve the stable electronic configuration of a noble gas.
Why the electrical charge in an atom is zero or neutral?
There is a neutral charge on an atom when the number of protons is equal to the number of electrons. This is most common in the Noble gases, such as Neon (atomic number 10, the second Noble Gas), where there are 10 protons and 10 electrons, with the negative charge on the electrons balancing out the positive charge of the protons exactly.
How many electrons does a sulfur atom gain when it becomes a sulfide ion?
A sulfur atom gains 2 electrons when it becomes a sulfide ion.
How many electrons does S2- have if sulfur has an atomic number of 16?
A sulfide ion, S2-, has 18 electrons. A neutral sulfur atom has 16 electrons, the same as the number of protons, which is the atomic number. Since electrons have a negative charge, a sulfur atom must gain two extra electrons in order to form the sulfide ion with a charge of 2-.
How does a sulfur atom become a sulfide ion why does it have a tendency to do so?
The sulfur atom only has 6 electrons in its outer shell, and following the octet rule, it wants to get to the closest noble gas. The elements want to have a full outer level, so it will gain 2 electrons to get to 8. So the Sulfur atom now becomes a Sulfide ion.
How does an atom of sulfur-36 become a sulfide ion with a -2 charge?
An atom of sulfur-36 can gain two electrons to become a sulfide ion with a -2 charge. When it gains these two electrons, it achieves a stable electron configuration, similar to the noble gas configuration of argon, resulting in a charge of -2.
Which atom has ten protons and ten electrons?
The noble gas neon has ten protons and an equal number of electrons.
What does the statement 'that an atom or an ions is isoelectronic with a noble gas mean?
It means that the atom or ion has the same number of electrons as a noble gas, thus adopting the stable electron configuration of the noble gas. This typically involves attaining a full valence shell of electrons. This concept is used in chemistry to describe similarities in chemical behavior between the atom or ion and the noble gas.
How many valence electrons are in a sulfur atom and a sulfide ion?
A sulfur atom has 6 valence electrons, while a sulfide ion has 8 valence electrons because it gains two electrons to achieve a stable electron configuration.
How does one determine the number of core electrons an atom has?
subtract the group number from the atomic number
The number of electrons in a helium atom?
Helium has only two electrons. It is the first noble gas in the periodic table and has a full outer electron shell.
Select the answer that correctly indicates the number of protons and electrons for this atom or ion Sulfide ion?
The sulfide ion (S²⁻) has 16 protons and 18 electrons. This is because the element sulfur (S) normally has 16 protons and 16 electrons, but by gaining two extra electrons to achieve a stable electron configuration, it becomes the sulfide ion with 18 electrons.
Which atom has two more electrons than an atom of a noble gas?
The Alkaline Earth metal which comes just after the noble gas
How many electrons does n need to gain to becom isoelectronic with a noble gas?
An atom with atomic number n needs to gain enough electrons to have the same number of electrons as the nearest noble gas in the periodic table. This would typically involve gaining 8 electrons to achieve the stable electronic configuration of a noble gas.
