The element group which is least likely to form ions is 4A group
<u><em>explanation</em></u>
Element of group 4A has 4 valence electrons. for example Carbon which has [He] 2S2 2P2 electron configuration has 4 valence electrons.
Since 4A elements has 4 valence electrons , it means that their valence shell is half filled which is relatively stable. <em>For this reason 4A element readily form ions.</em>
Answer:
Average acceleration = - 2 m/s^2
Explanation: Have a nice day
Answer:
Change in plate tectonic leads to change in earth surfaces.
Plate tectonics have changed Earth’s surface over time because the earth surface is placed on these plate tectonics. Earth's outer surface is divided into various plates that slowly move over the mantle which changes Earth's surface over time by merging and separating of landmasses that turn into continents.
The movement of tectonic plates is responsible for the creation of landforms such as volcanoes and ridges. Some volcanoes are formed when the tectonic plates pull apart from one another whereas some volcanoes are produced when a tectonic plate slides over one another so we can conclude that change in plate tectonic leads to change in earth land forms.
Explanation:
<span>With any element, there are a range of isotopes . . . a weighted average mass is used because there exist different isotopes of that element, each of varying mass. A weighted average accounts for the fact that the average mass (that may likely be measured from a random sample of the element) will most likely reflect the average mass of the more abundant isotopes. So the weighted average mass will be most comparable to the more abundant isotopes.</span>
