Question

plz ans all the true false

Answer 1

1. F, electrons are almost weightless when compared to protons.

2. T, to make it electrically neutral.

3. T, because the nucleus is concentrated at the centre. The electrons move about the nucleus.

4. F, it has protons which make it positively charged.

5. F, they are different for each level.

6. T, they are isotopes of carbon.

7. T, because it loses it's only electron.

8. T

9. F, both are same because Na loses one electron to attain it's nearest atomic configuration which is Ne.

10. F, it has only one shell and two electrons.

11. F, it's a metal and loses two instead.

12. T

13. T, ionic like NaCl and covalent like Cl(2).

14. F, it's formed through sharing of electrons among electronegative elements.

Hope this helps.
