Carbon and it's compound
Group 4A (or IVA) of the periodic table includes the nonmetal carbon (C), the metalloids silicon (Si) and germanium (Ge), the metals tin (Sn) and lead (Pb), and the yet-unnamed artificially-produced element ununquadium (Uuq).
The Group 4A elements have four valence electrons in their highest-energy orbitals (ns2np2). Carbon and silicon can form ionic compounds by gaining four electrons, forming the carbide anion (C4-) and silicide anion (Si4-), but they more frequently form compounds through covalent bonding
as a group 14 element, has four electrons in its outer shell. Carbon typically shares electrons to achieve a complete valence shell, forming bonds with multiple other atoms.
Carbon (C), as a group 14 element, has four electrons in its outer shell.
The chemical formula of perbromate is (BrO4)-
The chemical formula for tin that loses four electrons is Sn4+
Select all of the statements that are true.
Each orbit holds a fixed number of electrons.
The n = 1 orbit can only hold two electrons.
Each orbit can hold an unlimited number of electrons.
Each orbit is limited to a maximum of four electrons.
We have the following sub levels (s,p,d,f) and orbitals (each orbital receives at most two electrons).
sub-level s = 0 (has 1 orbital)
sub-level p = 1 (has 3 orbitals)
sub-level d = 2 (has 5 orbitals)
sub-level f = 3 (has 7 orbitals)
Each sub-level accommodates 2 to 14 electrons, but it is known that each sub-level has a number of orbits and that each orbital can accommodate a maximum of 2 electrons
Now, If for n = 1, we only can have:
1- (TRUE) Each orbit holds a fixed number of electrons.
2- (TRUE) The n = 1 orbit can only hold two electrons.
3- (FALSE) Each orbit can hold an "unlimited" number of electrons.
limited (one or two electrons)
4- (FALSE) Each orbit is limited to a maximum of "four" electrons.
maximum (two electrons)
The statements 1 and 2 are true
