What kind of elements has less than 4 valence electrons?
All metallic substances are a good conductor of electricity. These elements have less than 4 electrons in its outermost shell that means it has less than four valence electrons.
Does oxygen have 4 valence electrons?
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell.
What type of atom has 4 valence electrons?
Carbon
Carbon has four valence electrons and here a valence of four.
Which family below has 4 valence electrons?
The carbon family consists of the elements carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). Atoms of elements in this group have four valence electrons. The carbon family is also known as the carbon group, group 14, or the tetrels.
What is the group number of oxygen?

How many valence electrons are there in O2?
There are 12 valence electrons available for the Lewis structure for O2.
How many valence electrons exist in O2?
According to electronic configuration, Oxygen has 6 valence electrons. In O2−, there are two more electrons. Hence the number of valence electrons in the O2− is 8.
What elements has more than 4 valence electrons?
Comparative chemistry The nonmetals (except boron) are in the groups to the right of Group 14; each has more than four electrons in its outermost shell and tends to acquire electrons to complete its octet, forming negatively charged ions.
What kind of element has more than 4 valence electrons?
What is the valency of oxygen with 4 outermost electrons?
Atoms having four outermost electrons possess both positive and negative valency, and atoms having eight outermost electrons, valency will be zero (i.e. noble gases). Elements like oxygen can reach the stable state (nearest inert gas configuration: Ne) by getting 2 electrons. So that the valency of oxygen is 2.
What is an atom with only one valence electron?
Atoms consisting of less than 5 electrons in their valence shell. Example- Sodium has 11 electrons with an electronic configuration of 2, 8, 1. It has only one valence electron.
Why do atoms have 8 valence electrons?
The valence electrons are indicative of the properties of the atom. The reason for this is that atoms try to attain stability by filling their valence shell with 8 electrons (Octet Rule) Atom either gain an electron (s), lose an electron (s), or share electrons to form a covalent bond to attain an inert gas configuration.
How many electrons does oxygen have in its nucleus?
As its atomic number is 8, it has 8 protons, and for neutral oxygen, the number of protons are always equal to the number of electrons i.e. has 8 electrons in its nucleus. Electron configuration is the arrangement of electrons on the orbitals. The oxygen atom has a total of 8 electrons so, we have to put 8 electrons in orbitals.
