Why does Beryllium have a larger first Ionization energy than boron?
Nata [24]
This is an exception to the general electronegativity trend. It can be explained by looking at the electron configurations of both elements.

<span>Be:[He]2<span>s2
</span></span><span>B:[He]2<span>s2</span>2<span>p1

</span></span>

When you remove an electron from beryllium, you are taking away an electron from the 2s orbital. When you remove an electron from boron, you are taking an electron from the 2p orbital. The 2p electrons have more energy than the 2s, so it is easier to remove them as they can more strongly resist the effective nuclear charge of the nucleus.

Explain what will happen to the organisms that is affected by human activities.
Ira Lisetskai [31]

Answer:

Human activity is by far the biggest cause of habitat loss.

Humans are now responsible for causing changes in the environment that hurt animals and plant species. We take up more space on Earth for our homes and cities. We pollute habitats. ... Human activity often changes or destroys the habitats that plants and animals need to survive.

Explanation:

Human activities are the various actions for recreation, living, or necessity done by people. For instance it includes leisure, entertainment, industry, recreation, war, and exercise.

Over time, destruction of such habitats leads to reduced biodiversity, weakening the Earth's ecosystems, and ultimately posing a major threat to human life. While, significant tracts of habitat have been lost, and along with them many species of plant and animal, steps can be taken to slow and even reverse the process.

One of the most significant ways in which humans have impacted on the lives of other species is by causing climate change. Many animals, including birds and frogs, now breed much earlier in spring in Britain than they did 20 years ago. Whether or not this is having a harmful effect on them has yet to be determined.
