Question

PREPARED BY: DATE: PROJECT TITLE Deter niae whether each stardemeaxt is t rue or false.efalsey strect it TE) 771ー-ion contains 53 protons and 54 elecho ica clectons

Answer 1

• Atomic no = No of protons
• No of electrons= No of protons - charge on atom

1)Atomic no of Magnesium =12

No of protons =12

No of electrons = 12 - 2 = 10

Therefore ,no of protons=12 and no of electrons=10

Ans= False

2) Atomic no of Iodine( I) = 53

No of protons= 53

No of electrons= 53 - (-1) = 54

Therefore no of protons= 53 and no of electrons= 54

Ans=true

3) Atomic no of titanium = 22

No of protons= 22

No of electrons = 22 - 2 = 20

Therfore no of protons is 22 and no of electrons is 20

Ans ) False
