<h3>Further explanation
</h3>
Given
Atomic symbol
Required
Atomic composition
Solution
Atomic number = number of protons = number of electrons
Mass Number (A) is the sum of protons and neutrons
Number of protons and Number of Neutrons in nucleus
Number of electrons in the shell
From the picture:
protons = 3
neutrons = 4
electrons = 3
atomic number = protons = electrons = 3
mass number = protons + neutrons = 3+4 = 7
Ca(OH)2 is a strong base.
It’s name is calcium hydroxide and often it is easy to tell if something is a strong base if it has (OH) in the name.
Answer:
