Chlorophyll captures the sun's energy and is used as energy to complete the photosynthesis process
The loss of electron from an results in the formation of cation represented by the positive charge on the element whereas gaining of electron results in the formation of anion represented by the negative charge on the element.
The alkali earth metal beryllium (
) belongs to the second group of the periodic table. The ground state electronic configuration of
is:![1s^{2}2s^{2}](https://tex.z-dn.net/?f=1s%5E%7B2%7D2s%5E%7B2%7D)
From the electronic configuration it is clear that it has 2 valence electrons in its valence shell (
).
After losing all valence electrons that is 2 electrons from
orbital. The electronic configuration will be:
![1s^{2}2s^{0}](https://tex.z-dn.net/?f=1s%5E%7B2%7D2s%5E%7B0%7D)
Since, lose of electron is represented by positive charge on the element symbol. So, the beryllium will have +2 charge on its symbol as
.
Hence, beryllium will have 2+ charge on it after losing all its valence electrons in the chemical reaction.
The gases we create are adding to that blanket making sun light harder to escape,so the world heats up due to this addition to the layer
The Earth's structural zones (S-Zones) are the lithosphere, asthenosphere, mesosphere, inner core, and outer core.
C-Zone S-Zone What are they like?
Core Inner Core Found about 2,900 kilometers below
the Earth's surface. It is about 2,300 kilometers thick
Answer:
Infectious diseases are commonly transmitted through direct person-to-person contact.
The main four pathogens are virus, bacteria, protists and fungi.
Bacteria, fungi and protists can reproduce wherever the conditions are warm, with plenty of moisture, nutrients, and space. Viruses can only reproduce by invading living cells.
