Question

find the following terms of the elements calcium and chlorine
●Atomic number and Atomic mass
●No. of electron,proton and neutron
●Electronic configuration in s,p,d,f and K,L,M ......... form
●No. of valence electrons and valency

PLEASE ANSWERRR PLEASEEE​

Answer 1

Answer:

• Atomic number of chlorine is 17
• Atomic mass of chlorine is 35.453 u
• Atomic number of calcium is 20
• Atomic mass of calcium is 40.078 u

• calcium
• electron=20
• proton=20
• neutron=20
• chlorine
• electron=17
• proton=17
• neutron=18

• Electronic configuration of calcium in s,p,d,f form is 1s22s22p63s23p64s2
• in klmn form it is (2,8,8,1)
• Electronic configuration of chlorine in s,p,d,f form is 1s22s2p63s23p5
• in klmn form it is (2,8,7)

• no of Valence electrons in calcium is 2
• valency of calcium is 2
• no of Valence electrons in chlorine is 7
• valency of chlorine is 1
