Answer: Option (d) is the correct answer.
Explanation:
An atom or element which has the ability to readily gain an electron will have high electronegativity.
Both Beryllium and Calcium are alkaline earth metals and hence they are electropositive in nature.
Whereas both iodine and nitrogen are electronegative in nature. But across the period there is an increase in electronegativity and down the group there is a decrease in electronegativity.
Nitrogen belongs to period 2 and iodine belongs to the bottom of group 17. Thus, we can conclude that nitrogen is more electronegative than iodine.
I think it’s copper bc it’s a type of metal
2) carbon and hydrogen only.
A gas does not have a specific shape or volume (so we reject option A), instead it adjusts itself to the container (which is further influenced by other forces such as gravity and temperature) and it with time, willl fill the whole container evenly, so the correct answer is:
(2) It takes the shape and the volume of any container in which it is confined
Answer: The mass of the sample is 1264.800 kg.
Explanation:
Mass of the piece of copper = m
Volume of the copper price = 
m = 1,264,800 g = 1,264.800 kg (1 kg = 1000 g)
The mass of the sample is 1264.800 kg.
