Refer to the table below. Credits to https://terpconnect.umd.edu/~wbreslyn/chemistry/naming/IonicCharge2.jpg
Cations with (+ ) charges lose electrons in order to obtain an octet (8 valence electrons) when they ionically bond with another ion. We're looking for the ions that loses electrons here. So, from the table:
Al 3+ , S 2- , O 2-, Ag + , Ne ( noble gas, no charge)
Since Al and Ag has (+) charges, they are going to lose electrons to form ionic bonds with other atoms.
Answer:
B. Group 17
Explanation:
The element is Bromine. Its electron configuration is:
1s2 2s2p6 3s2p6d10 4s2p5
You can see that its last orbital is 4p^5 for 5 electrons in the 4p orbital.

Explanation:
Liquid because it is changing to that <span />
<u>10.45 kJ</u> heat would be needed to change the temperature of 100g water from<u> 10°C to 50°C</u>.
Temperature is the degree of hotness or coldness expressed in phrases of any of several scales, inclusive of Fahrenheit and Celsius. Temperature shows the direction in which warmness electricity will spontaneously waft i.e., from a hotter body to a colder frame.
calculation:-
Heat = ms× change in temperature.
= 100 × 4.2 × 50-10
= 100 × 4.2 × 40
= 10.45 J
The heat of an item is the whole energy of all of the molecular movement inside that item. Temperature is the degree of the thermal power or common heat of the molecules in a substance.
