1. Which of the element is found in period 4 and is a member of group 17?

2. The electron configuration of a particular element is $1s^2 2s^2$. Name an element that has similar chemical properties?

3. Name an element that has an electron configuration that ends in $p^5$?

4. An element ending in electron configuration p6 would be classified as an

Answer:

1. Bromine (Br) is found in period 4 and is a member of group 17?

2. Element with electron configuration $1s^2 2s^2$ is Beryllium (Be). Elements of the same group (in this case $2^{\text{nd}}$ group) usually have similar chemical properties. That is why, Magnesium and Calcium have similar chemical properties to Beryllium.

3. An element that has an electron configuration that ends in $p^5$ is Fluorine (F).

4. An element ending in electron configuration $p^6$ would be classified as an inert gas.
