A. Atoms B and D are isotopes.
b. Isotopes are elements with the same amount of protons (thus being the same element) and have different amounts of neutrons. Since atoms B and D have the same amount of protons but different amounts of neutrons, they are isotopes.
Answer:
The correct answer is option D, Sb
Explanation:
Atomic radius of As = 185 pm
Atomic radius of N = 155 pm
Atomic radius of P = 195 pm
Atomic radius of Sb = 206 pm
If we arrange the following element on the basis of their atomic radius in the increasing order , we will get the following
N (155 pm) < As (185 pm) < P (195 pm) < Sb (206 pm)
Thus among all the given element Sb has the largest atomic radius
Answer:
\A.
Explanation: Bromine and arsenic have the same atomic radius, which is 115 and Potassium has an atomic radius of 220.
Answer:
boundary interactions: areas where plates move away from each other forming mid-ocean ridges or rift valleys.
divergent boundaries: this happens when 2 tectonic plates move away from each other. along these boundaries earthquakes and magma are common as they are rise from the mantle to the sruface making new oceanic crust.
convergent boundaries: this is an area on earth where 2 or more lithospheric plates collide. they will slide under one another creating a subduction.
transform boundaries: transform boundary is a fault along a plate boundary where the motion is predominantly horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction zone.
Explanation:
lithosperic means the solid outer part of the earth.
hope this helps and good luck! :) <3
