What is the relationship of ionic radius and atomic number?
As you move across a period from left to right, the atomic number increases and the ionic radius decreases. This is because the increase in positive charge in the nucleus attracts the electrons more strongly, pulling them closer to the nucleus, leading to a decrease in ionic radius.
Why do both atomic size and iconic size increase as you move down a group?
As we go down in the period, the energy level increases but the number of electrons on the outermost shell (valence electrons) stays the same. This means the nuclear pull on the electrons gets higher and higher thus the size of the atom decreases.
What is the periodic trend for atomic size from top to bottom in a group?
Atomic size generally increases from top to bottom within a group on the periodic table. This is because each successive element has an additional energy level of electrons, leading to increased electron-electron repulsion and an overall increase in atomic size.
Is AiPO a ionic bond or covalent bond?
AiPO is likely to have both ionic and covalent bonds. The bond between the metal ion "A" and the phosphate ion is likely to be ionic, while the bonds within the phosphate group are covalent.
Do cesium and calcium form ionic bond?
Yes, cesium and calcium can form an ionic bond. Cesium, a group 1 alkali metal, can donate an electron to calcium, a group 2 alkaline earth metal, leading to the formation of Cs+ and Ca2+ ions, which attract each other through electrostatic forces to form an ionic bond.
Why do both and atomic size and ionic size increase as you move down a group?
Both trends hold for both positive and negative ions.
What is the relationship of ionic radius and atomic number?
As you move across a period from left to right, the atomic number increases and the ionic radius decreases. This is because the increase in positive charge in the nucleus attracts the electrons more strongly, pulling them closer to the nucleus, leading to a decrease in ionic radius.
What is the trend in atomic mass going down a group?
The atomic mass will increase. As you go down a group in the periodic table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.
Why do both atomic size and iconic size increase as you move down a group?
As we go down in the period, the energy level increases but the number of electrons on the outermost shell (valence electrons) stays the same. This means the nuclear pull on the electrons gets higher and higher thus the size of the atom decreases.
Why is group 13 described as the swing group in the periodic table?
Because Group 13 elements form both ionic and covalent bonds readily.
What is the periodic trend for atomic size from top to bottom in a group?
Atomic size generally increases from top to bottom within a group on the periodic table. This is because each successive element has an additional energy level of electrons, leading to increased electron-electron repulsion and an overall increase in atomic size.
Why does niobium and tantalum have similar atomic size?
Niobium (Nb) and tantalum (Ta) have similar atomic sizes because they are both members of Group 5 in the periodic table, which means they have the same number of valence electrons and similar electron configurations. Additionally, they are close in atomic number, with tantalum being directly below niobium, leading to a gradual increase in atomic size due to the addition of electron shells. However, the increase is not substantial enough to create a significant difference in their atomic sizes, resulting in their similarity.
Is AiPO a ionic bond or covalent bond?
AiPO is likely to have both ionic and covalent bonds. The bond between the metal ion "A" and the phosphate ion is likely to be ionic, while the bonds within the phosphate group are covalent.
What trends do you notice about the atomic number and atomic mass as you move left to right across the table?
they increase by one going from left to right totally a guess
What are the is the atomic numbers of la and ac on the periodic table?
La has atomic number 57.Ac has atomic number 89.They both are first elements of lanthanoids and actinoids group respectively.
Do cesium and calcium form ionic bond?
Yes, cesium and calcium can form an ionic bond. Cesium, a group 1 alkali metal, can donate an electron to calcium, a group 2 alkaline earth metal, leading to the formation of Cs+ and Ca2+ ions, which attract each other through electrostatic forces to form an ionic bond.
How does bromines atomic radius compared to arsenic?
Bromine has a larger atomic radius than arsenic. This is because as you move down a group on the periodic table, atomic radius generally increases due to the addition of more electron shells. Bromine is in group 17, while arsenic is in group 15 on the periodic table.
