Answer: Option (d) is the correct answer.

Explanation:

Group 2 elements are also known as alkaline earth metals and they are rich in electrons.

For example, calcium is a group 2 element with atomic number 20 and its electronic configuration is 2, 8, 2. In order to gain stability, calcium loses to electrons and becomes Ca^{2+} ion.

Similarly, all the elements of group 2 donates electrons in order to form ionic bonds.

Hence, we can conclude that all group 2 elements have in common that they tend to form ionic bonds by losing electrons.

The correct answer would be the last option.  The property that is common to all group 2 elements is that they  tend to form ionic bonds by losing electrons making these atoms positive charge. They are called cations. These elements are beryllium, magnesium, calcium, strontium, and radium.

masya89 [10]
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell

How much work is done by a 35-watt light bulb if it is on for 1,320 seconds?
OleMash [197]

Answer:

The 35-watt light bulb does a work of 46200 joules in 1320 seconds.

Explanation:

From Physics we remember the definition of work (W), measured in joules, by the following integral equation:

W = \int\limits_{0}^{t} {\dot W} \, dt (1)

Where \dot W is the power, measured in watts.

If the power is stable in time, then the work can be calculated by the following algebraic equation:

W = \dot{W}\cdot \Delta t (2)

If we know that \dot W = 35\,W and \Delta t = 1320\,s, then the work done by the 35-light bulb is:

W = (35\,W)\cdot (1320\,s)

W = 46200\,J

The 35-watt light bulb does a work of 46200 joules in 1320 seconds.

Answer:

Answers are in parentheses.

In the Bohr model of the atom, the electrons move in fixed, (circular) paths around a dense positively-charged nucleus. On the other hand, the quantum mechanical model shows the probability of finding an electron as a (cloud) of negative charge.
