How does reactivity change from top to bottom in group1 does the same pattern hold in group2?
Reactivity generally increases from top to bottom in Group 1 elements due to the decrease in ionization energy. In contrast, Group 2 elements do not show the same reactivity trend as Group 1; reactivity generally increases from top to bottom due to the decreasing ionization energy, but other factors such as atomic size and electron shielding can also influence the reactivity patterns in Group 2.
Are the elements in group 18 reactive?
all the elements of group 18 are Nobel gases. They are very very less reactive.
What is the reactivity of group 7?
The reactivity of group 17 elements differ as you move down the periods. Group 17 elements are missing 1 electron from their valance shell making them highly votile and reactive.I'll try not to make this confusing:1. As elements get bigger, they have a higher level of reactivity. (More "pull" needed from protons in the nucleus in order to keep valance shell electrons in orbit).2. As you move from left to right in the groups, you have a higher level of reactivity.3. Groups 1 and 17 have the highest levels of reactivity (except hydrogen in group 1) because they are away by only 1 valence electron.
Describe the Reactivity of group 1 element varies with increasing atomic number?
The reactivity of Group 1 elements increases with increasing atomic number. This is due to the fact that as atomic number increases, the outermost electron is farther away from the nucleus, making it easier to lose and therefore more reactive. Additionally, the size of the atom increases down the group, leading to a weaker attraction between the outermost electron and the nucleus, further enhancing reactivity.
How the trend in the first ionisation energy helps to explain the increase in the reactivity of the elements as group is descended?
As you descend a group in the periodic table, the first ionization energy decreases due to the increasing atomic radius and the shielding effect of inner electrons. This lower ionization energy means that it requires less energy to remove an electron from the outer shell, making it easier for these elements to lose electrons and react. Consequently, the reactivity of the elements increases down the group, as they readily participate in chemical reactions by forming positive ions.
What happens to the reactivity of elements in group a as atomic number increase across a period?
they do becaused they want to do it
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
In a group labeled as A, as atomic numbers increase across a period, the reactivity of elements generally decreases. This is because as you move from left to right across a period, the elements have more protons in the nucleus, which leads to stronger nuclear charge and less tendency to lose electrons and react with other elements.
How does reactivity work with the elements going down the groups for metals and non metals?
For metals, reactivity generally decreases as you move down a group because the outer electrons are further from the nucleus, making it harder for them to be lost. Nonmetals tend to become more reactive as you move down a group because they have more energy levels and an increased ability to gain electrons. Overall, the reactivity of elements going down a group is influenced by changes in atomic size and electron affinity.
What are the most reactive elements in the group of akali metals?
The most reactive elements in the group of alkali metals are cesium and francium. They are highly reactive due to their low ionization energy and tendency to lose their outermost electron to achieve a stable electron configuration. Due to their reactivity, they are stored under oil to prevent reaction with moisture in the air.
What happens to the reactivity as you move down group 1 in the periodic table?
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
What happens to reactivity of elements in groups labeled a as atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
How does valency of elements vary going down a group?
The valency of elements tends to remain constant or increase by one going down a group on the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their valency. As you move down a group, the number of electron shells increases, allowing elements to either maintain their valency or increase it by gaining electrons to achieve a full outer shell.
What 4 alkali metals are the most reactive?
Alkali metals have increasing reactivity going down the group. Francium may not be considered as it is not a stable atom: it is radioactive. The next four are Cesium, Rubidium, Potassium and Sodium in decreasing reactivity order.
As the elements in Group 17 are considered in order of increasing atomic number the chemical reactivity of each successive element decreases increases or remains the same?
As you move down Group 17 (halogens) from top to bottom, the reactivity decreases. This is due to the increasing atomic size and electron shielding, making it more difficult for the outer electron to be gained by the lower elements in the group, thus decreasing their reactivity.
How do elements change going down the periodic table?
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.
