Which element is in group two period 4?
Ca or Calcium
What element is in period 2 and group 7?
Nitrogen. There are actually two periods classified as "5", more properly "V" (Roman numeral 5). VB, towards the left side of the Table, and VA, towards the right. In Group 2, there is no Period VB, only Period VA, which is nitrogen.
What two families does the element of calcium come from?
Two families ?? Calcium is an alkaline earth metal; located in group 2 and period 4 in the periodic table of Mendeleev.
What is the element in Period 4 that has two electrons in the p sublevel name?
The element in Period 4 that has two electrons in the p sublevel is germanium (Ge). It has the atomic number 32 and is located in group 14 of the periodic table. In its electron configuration, germanium has the outermost electrons in the 4s and 4p sublevels, with the 4p sublevel containing two electrons.
The period on the periodic table tells you what?
The group to which the element belongs and, therefore, its chemical properties.
What is helium's position on the periodic table?
In 18th group (zero group), 1st period. It is the first noble gas.
How many atoms of a Group 17 element would be needed to react with one atom of a Group 2 element Explain.?
Two of them. A group 2 element has two valency electrons whereas those in group 17 have 7. The latter need one electron to make an ionic bond so two of them can react with a single group 2 element.

How does reactivity change from an element in group 1 to an element in the same period in group 2?
Reactivity decreases from group 1 to group 2 within the same period. Group 1 elements, like lithium and sodium, are highly reactive due to their single valence electron, which they readily lose to form positive ions. In contrast, group 2 elements, such as magnesium and calcium, have two valence electrons, making them less reactive since they require more energy to lose both electrons. Consequently, while both groups are reactive, group 1 elements are generally more reactive than their group 2 counterparts in the same period.
How many syllables in eighteen?
The word eighteen has two syllables.
What element has the fewest valence electrons in period two?
In period two of the periodic table, lithium (Li) has the fewest valence electrons, with only one valence electron. This is characteristic of alkali metals, which are found in group one. As you move across the period, elements gain additional valence electrons, with neon (Ne) having eight.
Is argon chlorine?
No, argon is a noble gas with the chemical symbol Ar, while chlorine is a nonmetallic element with the chemical symbol Cl. They are two distinct elements with different properties and characteristics.
