Answer:
An atom that gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion. Picture 1.8 Some atoms lose electrons and become positive ions. Others gain electrons and become negative ions.
Explanation:
...
From each drop-down menu, a solid has (a definite volume and a definite shape), a Liquid has (a definite volume) and gas has ( non of the above)
<h3>The features of different states of Matter:</h3>
Matter is defined as anything that has weight and occupies space.
There are three states of matter that is in existence which include:
- Solid: The particles of solid are closely packed together and vibrate around fixed axes. That is why they have a definite shape and volume.
- Liquid: The particles of liquid, though attracted to each other,move freely over each other. That is why they have definite volume but not a definite shape.
Therefore, a liquid occupies the shape of its container.
- Gas: The particles of gas contain scattered molecules that are dispersed across a given volume.
Therefore, a gas neither has a definite shape nor volume.

Answer:
It is solid
Explanation:
Well a can i hard and solid because it is metal
Answer:
If both fluorine atoms are combine than each atom have 8 valance electrons and total valance electrons in both atoms are 16.
Explanation:
Fluorine is halogen atom. The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements can not be found free in nature. Their chemical properties are resemble greatly with each other. As we move down the group in periodic table size of halogens increases that's way fluorine is smaller in size as compared to other halogens elements.
There seven valance electrons in each halogen atom. They need one electron to complete the octet.
Fluorine atom combine with its another atom through covalent bond and share its one of valance electron with other atom thus both have 8 valance electrons and total valance electrons in both atoms are 16.
Answer:Group 1 elements have 1 valence electron, meaning they have 1 extra electron that can easily be donated to an atom in search of 1 more electron. When they give away that extra electron to form an ionic compound, they become more stable.
For example, Group 7A (Group 17) elements have 7 valence electrons, meaning they need 1 extra electron to be stable. Group 1 and 7A elements make splendid ionic compounds.
