What are Group 4 elements known as?
Group IV consists of two subgroups: group IVb, main group, and group IVa. Group IVa consists of titanium, zirconium, and hafnium which are generally classified as transition metals. The main group consists of carbonium, silicium, germanium, tin, and lead.
What is the electron configuration for Group 4 elements?
Group 4 Elemental Properties
| Element | Z | Valence Electron Configuration |
|---|---|---|
| Ti | 22 | 4s23d2 |
| Zr | 40 | 5s24d2 |
| Hf | 72 | 6s25d24f14 |
What are the group numbers of elements?
Groups are numbered 1–18 from left to right. The elements in group 1 are known as the alkali metals; those in group 2 are the alkaline earth metals; those in 15 are the pnictogens; those in 16 are the chalcogens; those in 17 are the halogens; and those in 18 are the noble gases.
What is the element in group 4 Period 4?
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member….Group 4 element.

Does group 4 Gain lose electrons?
If the elements in Group 4 form 2+ ions, they lose their p electrons, leaving the s2 pair unused. For example, to form a lead(II) ion, lead loses its two 6p electrons, but the 6s electrons are left unchanged, an “inert pair”. Ionization energies usually decrease down a group as electrons get further from the nucleus.
What is the element in Group 4 Period 4?
What are Group 5 elements called?
pnictogens
Group 5A (or VA) of the periodic table are the pnictogens: the nonmetals nitrogen (N), and phosphorus (P), the metalloids arsenic (As) and antimony (Sb), and the metal bismuth (Bi).
What does group number tell you?
valence electrons
The group number in the periodic table represents number of valence electrons of the elements in a certain group. For example, all the elements in Group−1 have 1 electron in their outer most shell.
What is group 2 called?
Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). In most cases, the alkaline earth metals are ionized to form a 2+ charge.
Is Group 4 metal or nonmetal?
Like silicon, germanium is used as a semiconductor, and is widely used in the computer industry. Silicon and germanium are both metalloids, having some characteristics of both metals and nonmetals….Group 4A.

How many electrons does group 4 have?
The number of valence electrons
| Periodic table group | Valence Electrons |
|---|---|
| Group 2 (II) (alkaline earth metals) | 2 |
| Groups 3-12 (transition metals) | 2* (The 4s shell is complete and cannot hold any more electrons) |
| Group 13 (III) (boron group) | 3 |
| Group 14 (IV) (carbon group) | 4 |
What are the elements in Group 4 of the periodic table?
Group 4 is a group of elements in the periodic table. It contains the elements titanium (Ti), zirconium (Zr), hafnium (Hf) and rutherfordium (Rf). This group lies in the d-block of the periodic table.
Which is the lightest element in Group 4?
Group 4 is the second group of transition metals in the periodic table. It contains the four elements titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The group is also called the titanium group or titanium family after its lightest member.
Which element has an atomic number of 4?
Element Facts for Atomic Number 4. The element with atomic number 4 is beryllium, which means each atom of beryllium has 4 protons. A stable atom would have 4 neutrons and 4 electrons.
How many chemical families does the periodic table have?
In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table, and the f-block columns (between groups 3 and 4) are not numbered.
