To answer this question,you must be knowledgeable on periodic trends. When the atomic number increases, that means that the trend of the property must increase both across the period and down a group. The alkali metals are the elements in the leftmost column, while the halogens are the second-to-the-last column. From the periodic trends shown in the picture,
<em> the property must be atomic radius.</em>
Answer:
Explanation:
Given that,
Mass, m = 10 g
Volume, V = 24 cm³
We need to find the density of the substance. We know that, the density of a substance is given by :
Density = mass/volume
So,
So, the density of the substance is .
Explanation:
Given that,
Mass number, A = 302
Atomic number, Z = 119
We know that, atomic number = no of protons
Protons = 119
Mass no. = No. of neutrons + No. of protons
302 = No. of neutrons + 119
No. of neutrons = 302 - 119
= 183
No. of electrons = No. of protons
= 119
