What is the process that results in the increase of atomic number?
The process that results in the increase of atomic number is nuclear fusion. This occurs when two atomic nuclei combine to form a heavier nucleus, leading to an increase in atomic number. Nuclear fusion is the process that powers the sun and other stars.
Which group of the main group elements contains the largest elements?
Group 18 (Noble Gases) contains the largest main group elements because they have the highest atomic numbers and largest atomic radii among the main group elements.
Lithium the first element in group 1 has an atomic number of 3 the secound element in this group has an atomicnumber of what?
The second element in group 1 is beryllium, with an atomic number of 4.
What element has the lower atomic number of any group?
Lithium is the element with the lowest atomic number in Group 1 (alkali metals), while hydrogen is the element with the lowest atomic number in Group 17 (halogens) and Group 18 (noble gases).
How does bromine's atomic radius compare to chlorine's?
Bromine has a larger atomic radius than chlorine. This is because as you move down a group on the periodic table, the atomic radius generally increases due to the addition of more electron shells. Bromine is lower in the same group as chlorine (Group 17 or 7A), so it has a larger atomic radius.
Which of these describes atomic radii as one moves from top to bottom within a group?
The atomic radius increases from top to bottom within a group.
How do the sizes of atoms vary within a group (family)and explain why?
The atomic radius increase down in a group; the cause is the lower attraction from the nucleus atoms with increased bigger atomic mass.
What causes the atomic size to increase within the groups of the periodic table?
The atomic size increases within a group in the periodic table due to the addition of energy levels as you move down the group. As you go down a group, each element has one more energy level than the one above it, leading to an increase in atomic size.
What are the two variables that affect size within a group?
Increase in positive charge draws electrons closer to the nucleus. Increase in the number of occupied orbitals shields electrons in the highest occupied energy level from the attraction of proteins in the nucleus.
Which organizational variables is are important to the study of group dynamics?
Organizational variables that are important to the study of group dynamics include communication channels, leadership styles, power structures, decision-making processes, organizational culture, and team composition. These variables can significantly influence how groups form, interact, and achieve their goals within an organization.
What trend can be observed among the atomic radii of main-group elements down a group?
The atomic radii of main-group elements generally increase down a group. This is because as you move down a group, the principal quantum number increases, leading to larger atomic orbitals and a greater distance between the nucleus and the outermost electron, resulting in a larger atomic radius.
How does the physical state of a metal change as the atomic number increases?
sticking to increasing at no within group: more soft
What is the term for a group of subjects that receives all variables except for the independent variables in an experiment?
control group
how does it compares atomic radius francium or cesium?
Francium has a larger atomic radius than cesium as you move down the periodic table within the same group. This is because as you move down a group, the number of energy levels or shells increases, leading to a larger atomic radius. Therefore, Francium, being further down Group 1, has a larger atomic radius compared to cesium.
What is the process that results in the increase of atomic number?
The process that results in the increase of atomic number is nuclear fusion. This occurs when two atomic nuclei combine to form a heavier nucleus, leading to an increase in atomic number. Nuclear fusion is the process that powers the sun and other stars.
Does atomic radius increase from top to bottom in a group?
Yes, atomic radius generally increases from top to bottom within a group in the periodic table. This is due to the addition of more electron shells as you move down a group, causing the outermost electrons to be further from the nucleus.
What are the general trends andpatterns within the periodic table?
Atomic radius increases down the group. It decreases along a period.
