Why do nonmetals tend to gain electrons to form negative ion?
There are two reasons for that. Non metals do not have octet of electrons on their valence shell. Addition of electrons help them satisfy octet tule. Non metals have high electron affinity and hence high tendency to gain electrons.
Covalent compounds form between?
Covalent compounds form between nonmetals by sharing electron pairs to achieve a stable electron configuration. This sharing of electrons allows both atoms to fill their outer electron shells and form a stable molecule.
What kind of bond would two nonmetals make?
Two nonmetals would typically form a covalent bond, where they share electrons to achieve a stable electron configuration. This type of bond occurs when atoms are both trying to gain electrons to fill their outer electron shells.
How many electrons does bromine need to fill its valence shell?
Based on the octet rule, bromine requires exactly one electron to fill its valence shell.
How many electrons are needed to fill valence shell in hydrogen?
The atomic number for hydrogen (H) is 1 in the Periodic Table of Elements and it has that number of electrons (Valence & otherwise). Hence H2O for water since Oxygen O needs 2 electrons added to its valence electrons to make the stable compound WATER.
How many electrons are needed in hydrogen helium carbon and oxygen to fill their respective valence shells?
Hydrogen has one electron and needs one more. Helium has two electrons and has filled shell. Carbon needs four more electrons to fill the valence shell Oxygen needs two more electrons to fill the valence shell

Why do group one elements have similar properties?
;need the same number of electrons to fill their valece shells ;have the same number of valence electrons
Covalent compounds form between?
Covalent compounds form between nonmetals by sharing electron pairs to achieve a stable electron configuration. This sharing of electrons allows both atoms to fill their outer electron shells and form a stable molecule.
How are valence electrons differ from other electrons in an atom?
The closer the number of valence electrons is to the number required to completely fill or deplete its outer shell the more likely the atom is to react. With other electrons in an atom the shells are full and they have little if any affect on the reactivity of an atom. Valence electrons are the only electrons that are available to be shared/transferred in a bond.
Why do elements as a family or group share similar properties?
Elements in the same group have the same number of valence electrons, which determines their chemical properties. This leads to similarities in reactivity and chemical behavior among elements in the same group.
Why nonmetals do not have free electrons which conduct electrical energy?
Because the outer shells are very close to the nucleus and the number of electrons in the outer shells are between 4-8. Therefore, they are not freed from the nucleus easily rather they look for some more electrons to fill its outer shell which is technically called as covalent bond.
How do nonmetals fill their outer shells when forming bonds with metal?
The positive and negative are attracted
Does helium have the same amount of valence electrons as the others in its group?
No it does not, there are shells and orbitals that determines how reactive an atom is. Helium has 2 valence electrons, which fill up its entire shell, so it is like a noble gas. the other noble gasses have 8 valence electrons, which fill up their entire shell.
How many electrons does bromine need to fill its valence shell?
Based on the octet rule, bromine requires exactly one electron to fill its valence shell.
What is the number of electrons to fill fluorine?
it has 7 valence electrons, which is the number of electrons on the outer energy level, so it needs 7.
What kind of bond would two nonmetals make?
Two nonmetals would typically form a covalent bond, where they share electrons to achieve a stable electron configuration. This type of bond occurs when atoms are both trying to gain electrons to fill their outer electron shells.
