whatdo element in 4th period have in common
they have the same energy levels
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
The energy sublevel (s, p, d ,f) is always the same.
No, period 1 elements are not more electronegative than period 2 elements. Electronegativity generally increases across a period from left to right, so elements in period 2 are generally more electronegative than elements in period 1.
Potassium (K) is a metal in Group I of the Periodic Table of the Elements. K has an atomic number of 19 and a molecular weight of 39.10 grams per mole.
NOTHIN !
they have the same energy levels
The period of bromine is the fourth period on the periodic table. It is in the same period as other elements such as potassium, calcium, and argon.
Elements at the center of a period tend to have the highest electronegativity and smallest atomic radii compared to the other elements in the period. Additionally, these elements often possess a stable electron configuration.
Three electrons in their valency orbit.
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
A period is a row of elements
Elements at the center of a period typically have the highest number of electron shells among the elements in that period. They also tend to have properties that are intermediate between metals and nonmetals. Additionally, elements at the center of a period may exhibit a balance between atomic size and effective nuclear charge.
Their valence electrons are in the same energy level.
Elements in the same group have more in common because they have the same number of valence electrons, leading to similar chemical properties. Elements in the same period have increasing atomic numbers and electron shells, but their properties can vary widely due to different numbers of electron shells and arrangements.
Arsenic, which is in the 15th group 4th period of the periodic table of elements and has an atomic number of 33.
