Answer:
Water droplets form on plants, allowing the plants to soak up the water over time rather than all at once.
Explanation:
Cohesion and Adhesion are the properties of water which affect the living and non-living on earth.
Cohesion means water is attracted to water.
Adhesion means water is attracted to other living beings.
Water is very cohesive in that it "sticks" to itself. Cohesion is what allows a water droplet to form, for example. When water molecules surround one another, they settle toward a low energy state. For water molecules, they are most stable when they form a ball surrounded by other water molecules. As the molecules "pull" together, the surface tension acts like a casing for the group of water molecules. If it weren't for cohesion, water molecules would behave very differently and we would not expect to see water droplets.
Cohesive and adhesive properties of water impact living things in many ways:
Water droplets form on plants, allowing the plants to soak up the water over time rather than all at once.
Water striders (insects) glide across water surfaces owing to the cohesive property of water.
Explanation:
Y has 13 protons and we know that Aluminium (Al) too has 13 protons.
So , element Y = Aluminium
• In an element , no. of protons = no. of electrons. So , Y has 13 electrons.
• Mass no. of Y (Aluminium) = 27.
• Also we know that ,
Mass number = no. of protons + no. of neutrons
So,
No. of neutrons = 27 - 13 = 14
• Valence electrons are the electrons which are present in the outermost shell of an element.
Electronic Configuration of Y = 2,8,3
So, Y has 3 valence electrons.
• We know that Y is Aluminium & Aluminium is a metal. So , Y is a metal.
• Valency of Y = +3
