How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs two electrons to have a filled outermost energy level.
What is a Adam when it's outer energy level is filled with electrons?
Stable.
Each row in the periodic table ends when an outer energy level is what?
filled. That would be 2 electrons for helium, and 8 electrons for the rest of the noble gases in group 18 on the periodic table.
How many valence electrons in fluorine are needed to have a filled outer energy level?
Fluorine needs 8 valence electrons to have a filled outer energy level, following the octet rule. Fluorine naturally has 7 valence electrons, so it only requires one more electron to achieve a stable octet configuration.
What element is a noble gas in the first energy level?
There are no noble gases in the first energy level. Noble gases are found in the last (highest) energy level of an atom. The first energy level can only hold a maximum of 2 electrons, while the noble gases have completely filled outermost energy levels.
How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?
Carbon's outermost energy level contains 4 electrons, and it needs 4 more electrons to have this energy level filled (total of 8 electrons).
How Many electrons does bromine have in its outermost energy level?
Bromine has 7 electrons in its outermost energy level.
How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs two electrons to have a filled outermost energy level.
How many electrons does it need to have in the outermost energy level filled?
8 electrons
How many electrons are in the outermost level of carbon how many electron does it need to have fill this energy level?
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
The Halogen family elements have how many valence electrons?
The halogen family elements have 7 valence electrons. This is because they have 7 electrons in their outermost energy level.
What two atoms will have their outer energy level filled with two electrons?
Helium and neon will have their outer energy level filled with two electrons. Helium has 2 electrons in its only energy level, while neon has 8 electrons in its second energy level.
What is a Adam when it's outer energy level is filled with electrons?
Stable.
What is the neutral atom that has its first two energy levels filled has 1 electrons in its third energy level and has no other electrons?
This atom would be lithium (Li). It has 3 electrons, with 2 electrons in the first energy level and 1 electron in the third energy level.
What are the electrons in the outermost energy level of an atom are called?
Completely filled octet.
What is the neutral atom that has its first two energy levels filled has 6 electrons in its third energy level and has no other electrons?
The neutral atom with the specified electron configuration has 10 electrons in total. This atom is neon (symbol: Ne), which has a total of 10 electrons and has its first two energy levels filled with 2 and 8 electrons, respectively, while the third energy level contains 6 electrons.
What percentage of the carbon atom's second energy level is filled?
The carbon atom's second energy level can hold a maximum of 8 electrons. Carbon has 6 electrons, so the percentage of the second energy level that is filled is 6/8 = 75%.
